How To Wire Turn Signals, Brake Lights, Parking Lamps, and Hazard Circuit Switch |

In this video we wire a turn signal, brake light, parking light and hazard light switch (4-way flasher) circuit. I use the American Autowire 500148 turn signal switch, along with two single throw double pole switches to control the whole circuit. I also use four 1157 two-filament light bulbs, two novita 2-pin flashers, and four fused wires. This style electrical circuit could be used for a hotrod, car, truck, motorcycle, ATV, side by side, or maybe even an electric bike. It’s up to you!

Great video. I recently bought a flatbed truck. It was bare bones so I'm in the middle of fabricating a reciever/bumper for it and tomorrow I'm gonna start wireing it up. Wireing has always been like witchcraft to me so this video has been really helpful

500148 is the key to this whole thing. I was very puzzled up until i realized all that one switch does. Thank you.

[@WiringRescue]

You are absolutely correct. I looked high and low for other switches that work the same way, and I did not find one. This switch is special and worth the $40 if it fits your dashboard decor!

[@terrylane7038]

@WiringRescue I'm finding them for 50 and it'll fit my dash as there's not really a decor. When did built this trike I think he was over pretty when it came to wiring. Wiring is scary.

Thanks for keeping it as simple as possible & explaining how it works ! I will be wiring my project as simple as I can .. & using LED , turn ,running lights & stop ... Nothing fancy nor extra .. just like the 1930's & forties .. thinking of using the old truck style steering column mounted controls with built in flasher .. it comes with pig tail wires .. keyed on & off power switch with separate starter button .. leaning towards fused individual power wire system rather than fuse box with relay system .. nothing complex extremely simple ! for my use only .. old school with new technology low heat & low amp draw , along with over kill wire size & properly fused .. my build vehicle has no long run wire over 8 ft .. it's a super tiny truck .. one wire GM alternator .. head light switch has built in dash dimmer switch it's all so a very old style GM truck push & pull style .. I might go with a floor mount High beam switch or toggle switch .. not sure yet just in the planning stage & gathering all the parts first ...

[@AztecWarrior69]

Using a DPDT switch for the hazards and 4 diodes you don't need a second Flasher and it is very easy to wire. Use regular Schottky diodes used for Solar panels. They have THICK leads and are easy to solder, crimp connectors to or just twist together. Solder or crimp the Cathode, with each of the turn signal wires that go to the American Autowire (25Amp @12V) 500148 Switch. The Anodes all go together and to the DPDT switch. Sounds Complicated but it's not. If you want to make it look more sleek, look up MBRF20200CTR 20 Amperes Insulated Dual Common Anode Schottky Half Bridge Rectifiers TO220F.

thanks for the helping me understanding this, i didnt copy you exactly i used 1 flasher and spliced off that so it powers both the turn signal and hazards. the i used 1 6 pin double pole switch instead of 2 switches so one way i get running lights and i flip the switch the other way and i get flashing power to my hazzards. now i have black out features to :)

as a 75yr old guy from the UK i always find your video's easy to understand ! - i wonder what part no. would be available over here equivalent to the 500148 ??- many thanks

[@WiringRescue]

Thanks! This switch is very unique and I haven’t been able to find another with similar functionality anywhere. So - you may have to grab one of these and have it shipped, or use some relays instead. 😢

[@creativewoodworkingbeyondt6878]

Great solution. Love the no-relays option. One quick thing - when you say the 4 ways flash the parking lights, don't you mean the higher wattage turn signal filaments?

[@Jimmyisabeast69]

I wish I watched this 10 years ago

[@TheJustinCase101]

So I watched your 6 relay video and now I've seen this one. I like this as it is more simple but I will need to add headlights onto the running light circuit. I am guessing i can come off the single throw dual pole with a relay and have that power the switch on the relay so that the headlight load is not on the same switch.

[@MiguelRodriguez-pz8wi]

Thank for the video. Would you recommend doing this way or with relays. I need to decide. Thank you

[@WiringRescue]

This way is a great option as long as you don’t go crazy adding more incandescent bulbs. If you start adding more bulbs, then you run the risk of reaching the amperage limits of the switches. The American auto wire 500148 switch is rated at 25amps @12v. I believe the others are 15amps @12v (that one is a guess). Each 1157 bulb can pull about 2.1 amps with both filaments lit. If you swap to LED’s throughout, then the amperage draw is super low, so adding bulbs is less of a risk. I have another method of wiring this circuit that I want to try, so stay tuned for future videos!

[@joncampbell5321]

Which gauge wire do you recommend for this setup? Great video!

[@lloydtucker]

hazards ,brake and parking lights are in my opinion safety circuits and should bypass the ignition switch. my understanding is that in practice the turn signals always pass through the hazard light light switch wiring, so when hazards are turned in it just bridges both turn signal wires to a battery live. but good basic circuit

[@brettbennett1740]

I like this!! Could you do this but with a cheap hot rod wiring harness to help us simplify our hot rod builds? Thanks for you knowledge and help.

[@kylescott4888]

Looking for a wiring diagram not using a dpst switch but I think I thought of an idea using relays to add on to this method

[@devontae4499]

I’m wiring something similar to this 11:19 on my custom motorcycle, however I am trying to figure out how to cancel the running/parking light whenever the turn signal is in use (for more visibility)

[@shaggyivey5698]

Great video! I’m trying to re do my whole turn signal/lighting system on my Jeep Cherokee. Can you add headlight/ dimmer switch to this circuit as well? Would you recommend this system using relays as well?

[@WiringRescue]

You should be able to use this diagram for the high and low beam headlights. kzbin.info/www/bejne/ZpnCi5V_d62AY68. As for relays - it’s necessary for the headlight circuit, but not for the rest unless you are added more bulbs to the circuit. The switches used can handle the four 1157 bulbs perfectly. Thanks a bunch for watching the video! I appreciate it!

[@Samsquatch69]

Great video!! I’m still a little confused lol

[@WiringRescue]

It’s normal to be confused with new topics - and everyone learns in different ways. You just need to find the best way for you!

[@jimmcerlean1891]

If you add in left & right cornering lights that are separately triggered by the respective turn signal, how would that wire in? Thank you.

[@mathewmagdaleno2264]

Would you be able to show a close up or diagram of the american autowire 500148 switch its hard to tell what wires go where ?

[@chuckrosensohn4806]

Nice and simple, thanks. Wanna maybe consider doing one for cornering lamps? I'm working on adding cornering lamps to my trailer (7'x16' Enclosed), to flood out from under it's wheel wells, activated by the turn signals as they become engaged. However, the cornering lamps do NOT flash. My set up is about 47' combined length, and at night it's almost impossible to see where my wheels of the trailer are as I turn/back into and out of streets and customers driveways. Main vehicle is not equipped with cornering lamps either, or I would just tie into them.

[@WiringRescue]

That is an absolutely terrific idea. I’ll add it to my to-do list. I *think it should be an easy-ish one to make. Thanks again for the idea and taking to time to watch the video!

[@beautyangel8023]

on this circuit where would i put relays and used of the factory switch? also with the high beam and low beam switch ! I would like to use the factory switch with the used of relays and make everything work ? could help me out ?

[@alexwilhelmi7428]

Can you make a video more explaining the brake lights and flashers working together because I don't understand how the brake lights works on both rear lights. Like where does the blue wire connect to?

[@TheRoadhammer379]

Alex, he literally explains everything you asked in this video

[@camt]

@Mark Tse I’m trying to wire rear led lights for a old jeep rn. They have 2 wires one for brake one for taillights. I also want to use a steering column turn signal stalk instead of this switch, is there a way to accomplish what he did with the American switch in the vid but without that. I want one wire from the light to do turn signals and brake, and other one to do taillights but I don’t get how the turn signal will override the 12v from the brake switch if both are used at the same time.

[@MrDumass2]

I think - When you have your breaks on - Then turn a turn-signal on - The break filament "Stays On"... ???? Your way works and I understand the reasoning, "To use one 1157 bulb"... I think, most lights have an 1157 & 1156 bulb... (Running lights - Break lights - Signals - Flashers are front & rear signals) - I'm not criticizing you, I'm just trying to clearing it up in my head...

[@valdaspecetauskas2859]

Thank for this video ! I have a questinion, how can I sepparate brake and turn signals, because I need to make a addional rear amber turn lamp on my Shevy G20 ? (EU style) Maybe you have a video like this ?

[@dustinminer2911]

If possible can you post what spots the wires hook to on the 500148 switch

[@MechanicForGMCCars]

What diode can I use for each circuet? I desire reverse current and voltage protection .

[@invent-tc9nm]

How is this done without the auto wire switch question? Mark. I have breaklights in blinkers that are going on together. Obviously I'm not going to rip apart the whole - to put in the auto wire switch so there must be some other way to do it.?

[@tryduck5571]

Had question about 500148. Is this just a standard dpdt 8 pin toggle switch with just two outside pins jumped to reverse pins on opposite side?i see on back they just add in jumpers and removed those outside pins and charge 4x as much for a 8 pin dpdt you can just jump across yourself. Cant see 50 for a 13 toggle just because they removed pins and added a jumper in back.

[@robertsamspon4232]

can you do the exact same setup, but with 2 rear lights on each side, lower bulb park and brake, and upper bulb with park and turn? Like a AC Cobra with 4 tails lights that are separate.

[@patrickutter3165]

Was wondering why you should wire the hazzard switch to the low filament parking light instead like every vehicle pretty much uses the high filament brake/turn single which would be more visible than the parking light?

[@VintageVaughnVehiclces]

In the factory wire harness for the 1976 Ford LTD what wires in the circuit and where are they can I import some 1156 turn indicators to the back of the car and stop interrupting my brake lights. Breaking up the 1157 and to 11:56 for breaking and parking lights is pretty straightforward and simple but it's that brake light interruption and sending power to the same filament when you release your foot off the brake is where I'm confused how to convert my car to 1156 bulbs in the back end pairs of each parking brake reverse turn indicators.

[@tonymartinez305]

How would I used this setup with an old light switch! (64 impala) and can I used relays also

[@steamy1225]

OK, Love your explanations on these circuits, but. The brake lights are wired to a hot all the time fuse and the hazards are not on the parking light side . They are on the brake /turn signal side the brighter filament , and on some older cars the parking and headlights are wired to hot circuits and cannot be turned off by the ignition key . My 83 Ford F100 is that way. My 88 Stang is that way too. I can turn on them lights without even putting the key in the ignition. And by using the 500148 switch you don't need any relays anymore?

[@WiringRescue]

You are totally right on all of that. This is just one method of many that could be done to accomplish lighting these lights. In this scenario, you don’t need relays as long as you don’t overload the switch or turn signal flasher with high amperage bulbs.

[@Nealhh]

Would you be able to do a video on this with led lights and the relays as well? I can’t figure out how to do it, not the best with wiring

[@jerrybutler1336]

so i need the switches attached to the dash and manipulate them individually when needed ???

Do you have diagram for the american autowire switch? Cant really tell what goes where

[@alphathefirstone1222]

okay question?? is running lights the same as parking lights? i ask this because it wire up my square body entire lights on your video with the relays.. all lights work except running lights (lights on all the time especially at night). so if this is get the "running lights " to work then I am going to this set up asap. at the current moment i have not running lights ..so are running lights the same as parking lights...??? also what happen to a relay???? can this setup work effectivly for a long term without a relay...??? thx

[@dalesanderson4764]

Thanks will done. Would be very helpful however, to show us a schematics of this 500148 switch. How it makes both brake lights work is a little mysterious.

[@WiringRescue]

The magic is inside the switch itself. I have not found any other aftermarket switches that work this same way. It’s what makes this switch special and more expensive.

[@garybernstine8318]

Do you have a schematic drawing also to go with it

[@72FrostyOne]

Quick question on the pressure switch and where you have the blue wire connected to. It looks like it connects to the yellow flasher wire. I am wiring through an ididit column and I am limited with wires to splice into. Can you assist with this question?

[@WiringRescue]

This design will only work if you are using the switch in the video from American Autowire. The flasher and pressure switch are each on their own terminal on the back of the switch. If you aren’t using this switch, check out my other turn signal and brake wiring videos. They may be a better option for your scenario.

[@1Dukecronic]

hi there can you help me please i just cant get my head around doing this but with the relay method as like your other video i need this setup fully functional but with relays, turn signal, brake light, parking light and hazard brake and parkers and turning in the one bulb. cheers

Great video. One question, if I may. Can you tell how each switch post on the American Autowire switch is actually wired? From this view it is impossible to tell how the brake signal is kept from interfering with the front turn signals/hazard lights. Thanks for sharing.

[@WiringRescue]

The magic is not in the wiring, it’s the switch itself. The inner working of the switch are what allow that functionality. I’ve researched the heck out of this and cannot find any other switches that do this, other than factory turn signal switches ofcourse.

[@bulldogstrut1]

No need to respond. Right after I asked this question I found the wiring diagram for the American Autowire 500148 which labels each post and its use. I should have checked for this sooner. Sorry, but thanks.

Great question! Many cheap 12v switches are rated for very low amperages, like 3-5amps for example. To allow a low amperage rated switch to control a larger amperage circuit, you need to use a relay. The relay (typically rated for 25-30amps) then tells the lights to turn on and off, and the low amperage switch tells the relay to turn on and off. If you were to run a 10 amp light circuit through a 5 amp switch without any relay, you would burn out the switch. However - the switch used in this video is rated for 25 amps (I contacted American autowire to ask), and that means you can use a wide variety of bulbs without worrying too much. Most 1157/2057 incandescent bulbs are about 2.5amps each, so even with 4 running at once, you’d only reach 10 amps, which is well within the safe zone of this switch. Hopefully that makes sense. If not, let me know and I will try again! Thanks for the great question!
