Turn Signals

Hey guys,

I pulled my bike out of the garage last night and got it running after the winter. I took it for a shakedown ride and noticed that the turn signal indicator on the cluster flashes really fast. The front left turn signal doesn't work and the rear left flashes quickly.

I would assume that the bulbs are bad in the front, but is that causing the issue for the whole system?

With that in mind, would you guys recommend replacing with OE turn signals/bulbs if necessary or have you guys used aftermarket LED or non-LED options that you would recommend? (I've been thinking about doing an LED swap for some time but don't have a whole lot of electrical background). Where would I find replacements?

Go online and take a gander at CustomDynamics.com These folks have a slew of LED sets and options for you. On mine, with the exception of the added-on front white LED running lights, the rest came from CustomDynamics (I think its spelled as one word.) You'll be very happy with how much brighter (and therefore more visible) your machine will be.

I haven't yet done my headlight.

Question for you, did you have to do any major mods to make their turn signals fit? Or was it essentially plug-n-play?

The actual LED lights are embedded in some sort of brownish material, I wish that I knew what that stuff was called. I can't speak for any other type bike's installation but on the 750 I needed to trim down the circumference with a roto-tool before it would fit inside my turn signal housings.

A bit dusty to do but easy and once done, its done. Zero other issues.

For my rear turn signals, I had to drill a small hole in the bottom of the housing because the factory wiring only feeds power to the turn signal portion of the setup. My particular LED package also allowed the turn signal housings to additionally function as always-on running lights and on top of that brake lights, too. So they needed separate wires for their power.

Sure, you can get just LEDs that literally plug in to the factory socket exactly like factory bulbs but you wouldn't have the added functions as my kit has. So if you want to add those functions there will be a little bit of soldering and such.

Still, it was fun to do and can be done in one day for sure.

Yes. The flasher relay is designed to flash faster when a bulb is burned out. Replace the front bulb and the flash rate will return to normal.

If you change to LEDs, this feature will bite you again, unless you replace your flasher with an LED compatible one. I think its a EP34? But I am not 100% confident in that number.
