LED Turn Signal Wiring

[rscottlow]

Does anyone have a diagram of the proper wiring for aftermarket LED turn signals? The guy I bought my bike from had installed them, and they were definitely not hooked up correctly...plus he did a shoddy job leaving wires exposed, etc. Left side turn signals were working correctly, but when you turned on the right side signals, it would activate both sides. Any help is much appreciated! I'd like to get them fixed since I'll be doing much more riding as the weather continues to improve.

Aftermarket signals use the same wiring diagram as OEM, but obviously the colors would be different.

Try removing the turn signal indicator bulb from the dash panel. If that fixes the problem, then you'll need to wire in a diode.

I just bought LED signals at cyclegear store.

same thing, left worked ok. Right side only 2 bulbs light up and the left side flashes also. 


Put old ones back on.

anyone have an idea if resistors are needed or something?

And if (when) they blink too fast, you'll need a turn signal relay made for the low load of led signals. I get mine from superbrightleds, but they have thenat auto part stores too.

DDon't even think about wiring in resistors - they overheat and defeat the purpose of led signals.

I found out that the factory set up won't work with LEDs. You have to install resistors or something like that on each of the turn signals. I just went back with regular turn signals, not factory, those things are hideous but some carbon fiber directional from Cycle Gear. As for the wiring, it's 2 wires to each light, simple and will work either way. The issue is that LEDS cause a low voltage signal to the relay and will cause them to malfunction at least that's what the guy at the local Suzuki shop told me.

DO NOT use resistors!

The reason resistors work with led signals is because they bump the voltage back up to normal, and the turn signal relay will function properly. But the voltage sent to the resistors has to go somewhere..... which it does in the form of heat. Not just a warm circuit board kind of heat, the kind of heat that can melt plastic and burn your hand.

My bike had resistors installed when I bought it, but it still wasn't done correctly. I pulled the resistors out, and right now I don't have functioning signals at all. I'll get around to fixing it sooner or later, but I don't have the stock signals so I'll have to make the LED signals work.

Nobody making a plug and play LED light setup?

Sorry to revive this old thread, but I'm finally going to try to find time this weekend to fix this thing. I'm planning a pretty long ride for Sunday, so my goal is to get it done tonight/tomorrow morning. I'm pretty ignorant when it comes to electrical stuff, so forgive me for the (probably stupid) questions. I found the below instructions in another thread...does this pretty much sum up what we need to know in order to get these wired up and working correctly? I've looked through thread after thread, and have had trouble finding what a thorough explanation for getting this done (again, probably a result of me not knowing much about electrical components). I've been riding for a few months without signals, and I don't particularly like doing that, especially when commuting to work on moderately busy roads.

Sorry to resurrect an old thread.

Here's another "elegant" solution according to the guys at customled.com:

1. Install their (or other) electronic flasher relay
2. Cut wires to stock indicator lamp in gauge cluster
3. Wire left turn signal wire coming from cluster as a permanent ground (-)
4. Remaining right wire from cluster becomes permanent positive (+)
5. Install diodes (part # 1N4001) on both left and right wires coming from blinkers (+ wire into diode gray stripe side)
6. Wire both left and right blinker wires with newly installed diodes to positive wire coming from gauge cluster

It isn't complicated if you buy a "no load" flasher relay

https://www.superbrightleds.com/moreinfo/flashers-load-resistors/cf12anl-01-led-bulb-electronic-flasher/781/835/

Just replace your stock flasher with something like the above and replace your turn signals with led signals and you're done.  Should take no more than 20 minutes including the time necessary to crimp on new connectors to your led lights.

Thanks! This helps a lot. What about the diode?

[lucas]

what diode?

[lucas]

If you get a true "no load" flasher you won't need any other components or modifications.  There are some products marketed as no load but are just knock off junk.  Buyer beware.

I both signal pairs to LEDs and added a couple of load resistors in the tail to make the OEM flasher happy, no heating problems if you use properly rated components and heatshrink connections.  Dash signal indicator also works correctly.
