So, I got some cheap bar end mirrors and the black block off plates from al at asb and was wondering what to do with the blinkers. Ended up buying some little amber led bulbs that fit perfectly in the spotter light housing and then just cut the wires and connected them to the blinker wires. They work good, not too bright, but work well enough, it's just now the blinkers are on crack and blinking fast as hell. I love the new look and am not going to be putting the stock mirrors back on. So I need a resistor to slow down the blinking, but don't know what kind to buy. I've seen someone on here that has done the same thing and wonder what you did, or if you just let them be.

I personally dont like the fast blinking, but I could live with it if I have too.

I'm in the field right now so I cant get any good pictures of the bike, but when I get back Friday I'll put up some pics.

Get the LED flasher relay from American Sport Bike..

Tom, I have the LED flasher from American Sport Bike, I can't seem to figure out where to put it to make it work as the turn signals are controlled by the gauge cluster.

stock front turn signals are leds, which have no resistance(when forward bias). they have an resistor built in to provide a resistance to the ic, if the ic detects current to high or too low, it increase the rate of flash of the turn signals.
just put an ohm meter across a stock mirror/ turn signal and make the resistance of the new turn signals match the resistance of the stock mirror/turn signal.
If you need to decrease, you put a resistor in parallel, if you need to increase the resistance you put it in series.
resistors add in series, so if you need to get to 200 ohms, and you have 50 ohms, you splice in a 150 ohm resistor.
if you have 400 ohms and need to get 19 ohms, you put a 20 ohm in parallel with the 400 ohm, Req= R1*R2/(R1+R2).

And make sure you get the right power rating for the resistor. Watts are Volts*Volts / R. So 13.2*13.2 / ohms.

good point reepicheep, but i would get a resistor that can with stand 15v volts, so it would be 15*15/ohms=power rating.

Easy way - replace flasher -

Being a flasher, it will have at most a 50% duty cycle, so you can probably get away with either. : )

As previously mentioned there is no relay/flasher unit on the 1125, the IC takes care of all that.

Motrax (amongst others ) sell resistors to put in parallel if needed.

That sux - nothing like a ten dollar resistor for 50 - lol

Since I specialize in raising dead threads I'll attempt to do so here, too!

Any chance someone who's done the mod (adding resistors) could post up a "how to" with a parts list and pics?? I am far too dumb with electrics to even attempt this on my own. Do you need a resistor for each blinker? What if you have the integrated tail light/blinker?

TIA!
