[@CajunGreenMan]

Revival Cycles released a video today on wiring in bar-end LED turn signals, but I don't think those Moto-gadget units need a separate diode. Helpful to watch both videos, I think.

[@ClassicOctane]

I had to use one on my Triumph with LEDs to get the turn indicator to work.

[@CajunGreenMan]

@@ClassicOctane I guess I'm struggling to understand when this kind of diode is needed and when it isn't. Don't really know a lot about motorcycle Electric Systems yet.

[@almostoemgarage8143]

Sweet, $5 and free shipping, sold! Great video, just ordered one!

[@tomvband]

just ordered one. I do not have an indicator light but i'm guessing this will still work.

[@Timeistheissue]

Have anymore your site shows sold out.. It's the fix I need

[@bbgdaddy5198]

Just an FYI - these are commonly referred to as a fix for metric bikes but this should also work on any bike with the 2 wire indicator light. Basically what is happening is that the indicator bulb is relying on the light opposite the selected indicator to provide grounding for it so that when one side is indicating, the other side is the ground. LED lights don't work this way so this kit is the fix and you are correct. I recently bought some cheap LED 3 wire bullets for my 1990 Harley Davidson and have the same problem. I originally just had solid lighting with no flash. I bought the LED flasher relay and through troubleshooting I found that it was flashing but all the lights would do was to dim. If I hooked the white wire (running lights) to the ground, I could get a bright flash via the red wire but all 4 would flash again. I narrowed it down to the turn indicator and realized I needed zener diodes on my indicator feeds to block the backfeed. I could make my own but was curious if anyone else already discovered this and made a kit so I began looking and ended up here. I am sure this will work on my older Harley with incandescent bulbs and 2 wire indicator but I can't speak to newer bikes with the canbus system. Thanks for doing the video and you did a good job of showing the issue and install. I will be buying my kit from you.

[@swordfish1120]

Do the diodes have to have a specific value? Did you also use a single LED relay for the LED brake, front and back turn signals conversion?

[@TheSmokie55]

TY for this video. Good info for future builds.

[@dummgelauft]

Where do you buy the Honda style bullet connectors?

[@adjbob56]

If the 4 flash at once problem is caused by single dash indicator light - and does not happen with the 2 dash indicator light models - can I just convert the vintage single dash indicator to a pair of them rather than the diodes to stock dash indicator bulb?

[@vernonlevy1447]

My 93 cb750 nighthawk has 3 wire. One ground one drl and one turn signal

[@poco6997]

Can some help with a Honda magna 1998 same situation, the wires are slightly different

[@newburyg]

Hi there does this fix work for a Honda 1978 CB400T Thanks?

[@albertluna1118]

Just ordered mine💪💪

[@vernonlevy1447]

What about the turn signal light, do they get connected normally?

[@poco6997]

Also will this fix the back light as well or dose the back also needs a diode ?

[@irajmh]

All you had to do was connecting right turn to one of indicator cennections and left to other indicator connection and when you turn right or left the other wire works as ground.

[@drjoelg9765]

My bike indicator is not at all glowing, can u tell wt is the prblm

[@garryburns5185]

Hey man when are you putting more videos of the kawasaki 750 build back on?🙄🤔great vids by the way,any chance of an old z900 or z1000 build?

[@ClassicOctane]

Uploaded one last week. Just waiting for parts at the moment. I should have some in by this weekend hopefully.

[@theressaottley6439]

The led lights were working fine but flashing fast. Took it apart to rewire neater and now when i turn front signal on both flash at the same time, but rear works properly. Any idea what the issue would be or does it require the diode?

[@lu52]

I just ordered one , I hope it will work on my 05 gs500

[@majo_kvc_]

Man , how did it work ? whered connect diods , I am going trough same with my gs500

[@mickaelhidalgo2239]

Im triyng it on my 96 sg500 and it wont work either, any tips here pls?

[@mattrick3720]

Hi .can u please help me ?? I have a lexmoto echo 50. The engine light flashes 4 times the stops then flashes 4 time again can u please let me no why .thank you .matt

[@billbill9897]

Wouldnt just changing the stock flasher relay to a electronic (led) flasher relay fix that issue ?

[@ClassicOctane]

No, the flasher relay needs to be updated for the light to flash at all. LEDs don't draw enough current to trip the stock one. This is to prevent power from traveling to the other signals.

[@-Sleep-Tube-]

What flasher relay did you use for this led set up?

[@Dongunawardena]

Question here, If I install turn signals with LED bulbs, flashers and the diode kit, but leave the indicator light non LED, would it be an issue? I have trouble finding no twist type LED cluster bulb.

[@marceloramirez2926]

What about if I have an aftermarket speedo with left AND right indicators telling me not just that a signal light is on but one for left and one for you right? The do I need 2 diods?

[@BrandonWarner-vm2hl]

Hello. I picked up a 86 Suzuki intruder project. LED headlight already installed. Flashers don’t work at all. Running lights only. Rears are currently missing. Wondering how to remedy this. Sincerely Noob to all this

[@KLRmurdercycle]

Have a klr with a trail tech vapour dash and did led signals and flash fast but work. Got another klr, mint, low km, and stock. Just did the same led setup and all 4 signals come on. This vid helped to track the bug. Getting a diode. Turns out the Vapour on the other bike is set up for led and the power stops at the dash. The stock klr does not. Many thanks🤘👌

[@bldeagle10]

Sweet video! Just ordered a diode pack for my 73 CB350F. Thanks man!

[@bigal7561]

You sir are Batman. You just fixed a problem I've been trying to fix for over a month. Tried to buy one of the diodes from you but I think you stopped making them so I bought elsewhere. There diode had to come with other parts but that's ok. Their instructions were not so good. I went to your place today after church (because I just got the diode in) and had a month long problem fixed in 10 minutes. Thank you my friend.

[@ajasher7786]

Will it work on my 1993 Honda cb 750 nighthawk

[@vernonlevy1447]

I also have a 93 honda cb750 nighthawk. Could you share what you have learned? Thanks

[@juandunas2381]

My Suzuki ls650 just to have a bad front bulb I replaced it and then the mess began, on the left side is working just good but when I turn the right one , blinker is too fast and also the left side is on too as well,any ideas what could be? Thanks god bless you!!

[@vernonlevy1447]

Whats up Classic Octain? I have a 93 cb750 I swap out the rear 2 wire turn signal with led one's. I change the relay to a led relay. Work beautifully. My front turn signal uses a 3 wire set up. I change them to led all the light comes on at once. I use a resister for each one, but not one side work as it should. When I switch to the other side all the light comes on (turn signal) will the wire set you are selling fix this problem? And how much do I need? Thanks

[@marknulle8169]

I bought a flasher relay for my 2004 Kawasaki Vulcan 800 when I installed my led turn signal and all of the flash when signals are turned on left and right. Indicator below speedometer doesn't flash. If I change the bulb will that solve my problem?

[@fernandos6330]

hi, first of all thanks for the video. very helpful information and well explained, wondering if you or someone here could help me, i got these led turn signals with 3 wires one for the running daylight and before installing the diode kit i tried by unplugging the light bulb of the indicator everything worked, day lights and turn signals, but when i installed the diode kit turn signals work but if i try the 3rd wire for running daylight it goes back to same issue,

[@samurai4real]

My Issue is when I turn the switch to the side they turn on but won't blink. But if I switch one of the bulbs to the Stanley bulb, it'll blink. I have Led bulbs, I have a led relay, but if I put both LEDs on front and back it won't blink. I am open to what ever advise the community has.

[@jermildimayacyac825]

Hi bro, my bike is honda cy50 1981 model,and the problem is the indicator not working properly, I already change the relay twice but its end up burning the flasher relay, can you please help me with this, thanks

[@mikegiblin7500]

I have an 82 cb900c with dual indicator turn signal bulbs. I upgraded all bulbs to LED, brake, turn, front and rear and turn indicator leds. Now all I get is; select rt turn rt.front just illuminates,no flash. Select left turn same result. In rear no turn signal or illumination, only brake lights work with front and rear brakes. On front left and rt. running lights shine when ign key is switched on & slightly brightens when turn selected either side. Do I need two of these diode harnesses,one harness for each ind led, and where to I connect them?

[@shannonsnow6350]

I have a 2004 honda vtx 1300....i just installed LED turn signals and i have a simular issue, will this work for me?

[@scovie1047]

I have a 2007 cbr1000rr the bike is set up with two indictor lights one for the left and right inside the cluster. So would I need two separate diodes or would one still work?

[@woodwilling291]

Just bought diode kit, it did fix the dash light but all 4 still blinking at once at regular speed. Any advice? Thanks!

[@robertfrank5481]

I have a 74 CL360 with no indicator on the instrument cluster, and can't seem to get the diode to work. Any thoughts?

[@Eana-of-Sussex]

Will you be making any more of these diodes... they're all sold out on your website...

[@TruththeRealist]

This worked for my 2010 Honda Shadow Phantom!!! Thank you for this vid!!!

Dude what wires did you cut? I have the diode and the ground wire too, how'd you do it? I'm lost! Thanks!

[@st-qd8wg]

My signals are oem 1157 bulbs and I put new flashers all I'm getting is solid light not blinking

[@STARCROSSEDMOTO]

Great video. Would these diodes be useful for me? I just installed LED turn signals that double as running lights, but my bike has only two wires for the indicators and the LEDs have three wires.

[@jimmywebb4533]

Would that work on a suzuki vz800 if so where would they connect to?

[@jamiestanley8774]

Nice work . I think ill have a crack at that . Is there a led bulb that fits inside original blinker ?

does this work if you flashers stay solid ?

[@jojoseg]

I can’t figure this out. I have a 1992 Honda nighthawk. Has 3 wire lights on it now but my new LED’s are two wire. No running lights just turn signal. The lights on it are grounded to green then one to running lights and the other to signal on both sides. How would I hook up my diode kit? For something so simple I am confused and I’ve emailed twice but no response

[@jojoseg]

Anybody have an idea?

[@upstatestorytellers6835]

Thanks for your videos. I’m new to all of this and your videos are extremely helpful. Just ordered this wire.

[@kmacdizzle]

I’m so confused lol. The orange and blue wires are you talking the ones that come from the bike or the turn signal. I wish I could find a shop near me that would work on a 97

[@kmacdizzle]

When you unplug the sb from the turn signal and ground it do you just leave whichever ground you unplug just out and not plugged into anything

[@gedconnor3373]

What value are the diode s bud

Can you tell me why it is happening?

[@telcobilly]

I had the same problem on '22 Honda XR150. I first added 2 rear LED signals which worked but would hyperflash. I replaced the flasher unit with an adjustable LED unit which fixed that issue. I got the 4 way problem when I added my front LED signals. The quick fix is to remove the dash indicator bulb. I did that and it all worked. I then installed a LED T10 bulb so now I get the indicator on R signalling only. My left signal wiring is orange and right side is lilac purple. Green for ground of course. I'd buy your adapter in a hot second if I wasn't in the Philippines. I'm sure the postage would be high. Can you tell me what diodes you used? Good video by the way!

[@EbolaSquirrel]

thank you! had the same symptoms with my honda ruckus (indicator super dim,and 4 way flash). were installing them today!

[@johnburden9109]

Bit different on mine. 2004 Honda vtx 1800 with 9 pin relay (quick fix would be to switch out 2 pin in other models but no). With LEDs wired up, when I turn the bike on, both sides flash like hazard lights. When I activate the switch, the correct side turns on and blinks fast. Obviously don't want to run around with both sides flashing all the time :D

Do you have to do this for the bottom two?

[@garciagarivo1007]

Did this for my 85 shadow, worked fine. As he says, plug the DIODE single side up to one of the cluster signals wires and the other wire from the cluster to a ground. Then connet the 2 DIODE ends to the signal wires. The running lights can go directly on to the signals.

[@Beerserker703]

I have aftermarket led rear blinkers that work fine. The front are still stock but I tried putting in led bulbs in the front. They are bright but hazard flash just the front two blinkers. The back flashes normal. Will this trick work for me or do I need a flasher relay? 2005 Honda Shadow Spirit 1100

[@michaelmcgrory774]

Is there instructions to install

[@NebFan06]

I installed LEDs on my 2003 Yamaha xvs1100 and got the hyper flash. Would these work for me? Also do I need two pairs since I am doing front and back?

[@f5snopro11]

03 z1000. integrated LED tail and aftermarket led arrows up front. my front blinkers are hit or miss. sometimes they're fine. sometimes they are constantly on at like 15% brightness constant, 30% brightness blinking. none of the issues like you're having, i just find it interesting that yours were super dim when you had all 4 blinking. do you think your wires would help my bike? i've been troubleshooting this issue for over a year now. i can't figure it out. they have no ground on the front led amazon blinkers, just 2 wires.

[@leonhorner1643]

Great video, i just ordered a diode kit from you, and i wonder if i have understood this right? i have four wires in front, two for each side, so 2 green, one blue and one orange. So the orange one i can just put directly to ground, the blue wire to the single connector on the diode kit, and then use the two remaining wires on the kit to each turn signal??

Hi. Thank you for this video. I just found myself having this same issue (LEDs all around, causes all LED signals to flash like hazards when any signal is turned on). If I leave 2 incandescent bulbs on either end, LEDs on the other. All is well, no hyperflash either. So, I have a 2007 Honda Shadow Sabre 1100, will your wiring fix work for me as well.

[@davidseabury3941]

Got my diode splitter kit a couple of days ago and did an installation. On a 2014 Kawasaki 900 classic. All worked perfectly after installing the LED flasher module, your kit and the LED bulbs. FYI, the grey and green wires can be accessed where they go in the dash connector by just undoing a little electrical tape. The black and yellow striped wire right next to them can be tapped for ground. Unless you choose to remove the gas tank, the hardest part is working in the little space afforded where the harness wires go down just behind the speedo assembly.
