That sounds like the winner.

Full throttle did you do that yourself with your rear pegs?

The flasher relay supplies/interrupts power to the switch and the switch completes the circuit to R or L blinkers, so I don't think an issue w/ the relay could be causing the problem you described, since it is located before the circuit branches @ the switch. It sounds to me like there must be a corrosion/rubbing 'bridge' (not a 'short', since that would be to ground) allowing a little current to pass from one side of the circuit to the other - I think that could only be between the switch & lights.

First place I would start is at the switch, as others said - but I'd suspect the wiring more.

Interesting mod on the led placement, kinda cool - clean off your sharpie marks though! :lol:

My concern is how visible it would be to other people behind you...Bc my bike with the undertail...has shitty placements for blinkers and they dont sell nice looking undertails...So if i could do something like this for my blinkers...I saw a brake light setup that i could do that goes under my rear seat.

nobody has mentioned the psychological answer: your turn signals are reflecting your thoughts on life and not knowing which way to turn :lol:

Are you saying Full Throttle is Bi-curious?

Since those aren't stock signals, I would first look at the "new" wiring going to those signals and if you put new signals on the front too. My guess is someone did a crappy job of installing them and the wires aren't isolated properly.

Ill try and get a diagram of the wiring.
Nah not me. came that way

Well i have no idea who put those lights in since the bike is 10years old and has probably 3-4 owners or more. Its very possible that anything suggested above is the answer. I'm going to mess with it more tonight. I haven't had a chance till today. My garage has been in a shambles due to spring cleaning.

The visibility is actually pretty good. Its pointing straight back so anything behind me can see them. The only thing that gets in the way is the muffler on the right side it causes a small blind spot to the blinker. If a car is in my back right pocket they wouldn't see it but i wouldn't be needing to merge that way if they were there lol. Other than that small blind spot for the blinker its fine. Ive never had any problems with them yet. And at night its pretty crazy bright.

I didn't see it mentioned in the thread but do the front indicators do the same thing? If not that really makes me think it is a wiring issue like others have mentioned. Either way, if this works I have hopefully attached enough of the relevant portion of the wiring diagram. I can't go too much bigger or it becomes unreadable. It is for Euro models but I suspect it will be the same.

46 is the relay, 44 is the switch, and 51-54 are the actual indicators. 43 is the clutch switch and irrelevant. It just ended up in my crop.

Ahh - It just dawned on me, I bet what may be causing it is a 'backfeed' through the dash indicator circuit which is producing a small voltage on the opposite-hand signal circuit.
Especially if your dash has a single flasher bulb vs. both right & left.

A bit out of my element with the electrical theory, so I'm speculating here - but:
With normal incandescent bulbs (low resistance, high amperage draw) maybe it wouldn't be enough to make the filaments glow, but LED's draw so little current that it could be enough to light them up?
