If your car has negative switched headlights, (Most Japanese cars from early 2000's) follow this guide guys! He does a really good job of explaining everything clearly and explains every part of the way. This is cheaper and better than any of the adapter harness's, which are really hard to find/determine which specific one you need for your car. I did this for a 2010 honda fit and most other Hondas from early 2000's would be the same. There's a comment in here about reducing the output slightly because of the diodes, I can say that I did notice it too but because the lights are so much better and brighter than the stock halogens it didn't matter to me. (Edit) Honda fits are positive switched headlights and this process will work fine you will just have to switch the orientation of the diodes.

[@bulgarianicedtea7897]

Another tip guys, keep your soldering iron hot and be as quick as you can with the diodes, these seem to bee extremely sturdy/ heavy duty but I have heard from other enthusiasts that they have ruined a couple of diodes by overheating them when soldering.

[@kesipi4465]

what led you use? i have h1 sized projector, and i wanna do my fit to

[@josh1859]

ive been messing around with my 2nd gen crv for 2 weeks now. this was the fix i needed. thanks so much 🖤🖤

[@ivanbarton4475]

Thanks, this is thw video that I needed. I thought about using diodes but didn't know which ones to use.

[@ed4647]

Great info, ordered from your Amazon link. For HIDs you could probably run those diodes if you're powering ballasts with a relay harness, just wire them to the relay coil circuit

[@NextLevelNeo]

Theoretically yes. HIDs are usually only 35watt, maybe 50. The biggest concern i would have with HID is that initial surge of power to ignite the bulbs. You can try, worst case youll fry some components, maybe the diodes, but they are beefy diodes so they should be able to take it.

[@ed4647]

@@NextLevelNeo oh I wouldn't wire the diodes to ballast power. I'm talking about connecting diodes to the OEM low and high + leads like what's done with the LED projectors, but they'll be connected to the "trigger" circuit of the relay. Very low current is needed to power those circuits.

[@NextLevelNeo]

@ed4647 oh, so still using a relay, yea that would be totally fine

[@headlightdesigngradacac]

I tryed that on a car that has projector low beam and a reflector high beam. When i installed bi led projector high beam works only if low beam is on so i used 10A10 diode so the high beam can work when low beam is off but diode is getting VERY hot.

[@NextLevelNeo]

On most cars like that the low beam stays on when the high beam is on and you won't need to use this style harness. What car is it?

[@mkmkain8488]

hii good day man. what lamps did you uesd? thank you for the video

[@sanwichg0dyt649]

i got a 09 ford focus and when i turned on the low beam they work but as u said in the vid the highbeam just turns the whole thing off will this fix it? just cant find anywhere for anything about the time of highbeam whether its negative or positive switched thanks

[@quadrunnerjake]

I like to instead add a relay kit to change from switched ground to switched positive. Use the wires from your original plugs high and low to activate the relay and give you full power straight from your battery. Plus it takes all the load off your factory switch

[@angerdark]

Hola soy de mexico no entiendo mucho ingles pero esta muy bien el video crees que esto funcione para instalar unos faros de un suzuki swift sport 2015 a un suzuki swift glx 2014 ya que el glsx trae H4 y los faros del sport traen xenon hid muchas gracias apreciaria mucho tu ayuda

[@edwardsjohnson5387]

Ill hire you to help walk me through wiring my led projectors.

[@francobuitrago5657]

Hi there, very good video. I have a situation. I bought Sanvi biled laser projectors 3". The projector has 5 wires, 2+ and 2-, for the low and high beams. I guess the fifth wire (yellow) is for the laser, but, when I join that one with the high beams, the projector turns off and restart. I am testing the projectors with a 14v laptop adapter, could it be the reason of not getting the laser beam? Or does the wire need diode? The projectors uses canbus because of my car (Hyundai Elantra i35 2013). But, another situation is, when a I connect the canbus, nothing work even the projector, and when I connect laptop adapter directly I can see the low beam and the hight beam, less the laser because of the fifth wire. Any guidance or information will be welcome, thank in advance.

[@belalsays]

can i use 10A10 diode, I can't find here in india

[@JuggernautCorps]

Has anyone tried this on a early 1st gen sequoia or tundra? I cant seem to get it to work for my 01 Sequoia

[@madoasful]

Using diodes is a simple and economical solution to power the low beam when the high beam is turned on, but I don't recommend it since it decays the power of the projector slightly, or in my case of using a biled low beam 70w the decay of intensity is too noticeable, I had to repeat all the wiring again and add a relay that positively feeds the low light with 70w. Generally positive battery

[@luisangelmancilla4601]

where did you add the relay?

[@madoasful]

@@luisangelmancilla4601 If your vehicle or motorcycle uses normal polarity (two positives and one negative), 85 and 86 would be negative and signal high light, 30 is low light projector and 87a is signal low beam, thus the relay comes (NC) permanently bonded 30 with 87A without the relay being active and thus gives you low beam, to pin 87 you connect high beam signal (85 or 86) making a bridge, high beam of the projector and that's it, when the relay is activated, it will activate high beam and through pin 30 it will power the low light of the projector, so you will not have to use diodes that cause voltage drop.

[@uptoolate65]

How different of a hookup is it if the system has power switches?

[@NextLevelNeo]

You just flip the diodes 180 degrees

[@stephenimsong3462]

so are the diodes so you don't ground both hi and low? could you omit the diodes if you want to run both hi/low at the same time all the time? i mean wouldn't the shutter do its job as far as not blinding people when in low beam? also i hear a 3d printer in the back

[@NextLevelNeo]

The diodes are a one way circuit. they prevent the signal from back feeding. If you want both hi and low all the time then you could just connect both high and low ground together. Without the diodes its just a basic power ground circuit, but this would open the shutter anytime the low beam is on, so you would be blinding people with the high beam anytime the projectors are on. You also need to consider each car varies. Some use ground switches some power. You will have to adjust the diode orientation and wire layout accordingly.

[@ESTroll]

Diodes are 30 amp 12v alright?

[@NextLevelNeo]

@ESTroll diodes come in many sizes. We used the ones at that link, results may vary with other sizes.

[@thehornstore]

Does this circuit harm the projector or any kind of an other issue?

[@NextLevelNeo]

If done properly, no, it will not harm the projector or the car.

[@thehornstore]

Do we need to put a relay or something for safety or this works fine without relay too ?

[@NextLevelNeo]

Generally no relay is necessary. But it would depend on the factory wiring gauge and wattage load of the projectors.

[@thehornstore]

@@NextLevelNeo okkk thanks

[@Albertautolight]

This one is 2.5 inch?

[@NextLevelNeo]

@@Albertautolight correct

[@patron1839]

No load resistors needed? I have an 03 ram and was told load resistors are needed to power the high beam.

[@NextLevelNeo]

On some cars you may need a canbus resistor. That will stimulate the load of a halogen bulb, if the car looks for that load and doesn't see it it may trigger a dash light or in some cases the lights won't work without it. I don't belive the 03 ram has that though, but i could be wrong. Either way that is separate from this harness.

[@patron1839]

Thank you. Yes my Ram requires it

[@jasonhughes9720]

Make a video like this for the 9007. I have an Srt-4 so that would be very useful for me. Thanks

[@NextLevelNeo]

The process is the same you just need to find a pinout for the 9007 to determine which pins do what. Even with a 9007 not all cars are the same.

[@thevinylwrapper]

I tried for hours with my Hyundai Getz harness and only managed to burn the headlight fuse a few times. Can't figure out how it works. I tried from one positive to another (when you power the high beams you would also power the low beams, doing a jumper with the diode between both but didn't work) tried the way in this video and also didn't work. I ran out of ideas :(

[@NextLevelNeo]

@@thevinylwrapper what year Getz? Is that

[@thevinylwrapper]

@@NextLevelNeo 2007 buddy

[@NextLevelNeo]

@@thevinylwrapper does the headlight have 1 bulb for high and low beam with 3 wires on the plug inside the light?

[@thevinylwrapper]

@@NextLevelNeo yep

[@thevinylwrapper]

@@NextLevelNeo it's a normal H4 with the square type plug. With a multimeter I checked the pins and I got constant 12v on the side parallel ones and negative on the top centre pin. When you turn the switch on to low beam only one side has 12v and the top is still negative but if you flick the high beams the negative top dies, the left positive dies and the right pin now is the one with 12v but the other two pins are dead (in another words, unless I earth it directly to the car I can't get the high beams to close the circuit...) Weird :(

[@danmccarthy5247]

do you happen to make a harness for an 04 Honda Element using Gzminjie 3" ? It has a red, Black along with smaller white and yellow wires.... HELP!

[@NextLevelNeo]

We don't make harnesses but you can follow this guide to make your own.

[@danmccarthy5247]

great video although still unclear which wires go where on the 3 prong plug?? TY Dan@@NextLevelNeo

[@NextLevelNeo]

@@danmccarthy5247 that's because there are many different variations. You have to figure out what layout your car has. This is why we don't just make a harness and sell it. There are too many variations.
