i just finished my turn signal stop light conversion. first let me start by saying that i've been run over twice from behind by daydreaming motorists so i wanted a really noticeable difference between stop and runnig lights. i still plan on getting one of roberts xb lights, but i wanted to add the stop feature to my turn signals. first i located an inoperable pair on ebay for $20. i built a 20 led circuit with 50,000 mcd bright 5mm minis for each turn signal. hard part done. by the way, your amber signals will work fine. i just wanted red ones. then i stopped by walmart and picked up the hopkins tail light converter for trailer applications and a 4 prong pin connector for a whopping $19. i've enclosed pics so you guys can get the product numbers if you like. now i hooked them up so the turn signals work as brake lights but not the running feature so drivers can really tell something happened when i apply the brakes.
it's really simple and only took me about an hour. i did the job while installing my fender eliminator.
here's what you need.
*a soldering iron or butt connectors and crimp tool. i prefer to solder
*heat shrink tubing and cigarette lighter
* cutting pliers and wire strippers
* electrical tape

(1) start by splicing the red wire on the input side of the module to the brake wire. i just pulled the tail light and spliced close to where the wire terminates then heat shrink it.
(2) run the white wire to a ground on your bike somewhere. i did the same thing and just spliced it to the tail light wire close to the termination point.
(3) the right turn signal on your bike is brown and black. unplug the light. cut the brown wire about one inch before it meets the connector. be sure to leave a little wire at the connector you'll need it in a few minutes. connect the green wire from the
module to the brown wire.
(4) the left is purple. follow step three and connect the yellow wire from the module to the purple one.
(5) there will be a leftover brown wire. cut it about an inch long and heat shrink over the end. you wont need it.
done with that part.

(6) plug in the 4 prong connector and securely wrap the area where the prongs connect with electrical tape. just to make sure that it doesn't come into contact with some other electrical or grounded part later.
(7) connect the turn signal connectors that you cut from the bike earlier to the corresponding output leads. the purple piece you cut earlier to the yellow on the 4 prong connector. then the brown from the bike to the green on the 4 prong connector. there are now two left over wires on the 4 prong connector. white and brown. cut them about one inch and shrink wrap them.
(8) now pluc you turn signals in. rember we didn't cut the ground wires to the turn signals so plug your black ends back to the original mates. plug the yellow wire from the 4 prong connector to the left purple(+) wire on the signal. now plug the green wire on the 4 prong connector to the right brown(+) on the signal.
(9) you are now finished. all that's left is to secure the module and tidy up the wire. i just drilled a small hole in the plastic fin right behind the battery box and ran a small zip tie through the around the module and cinched it in right where my tool kit was.

this job should be within the skill level of just about anyone. don't be afraid to try it. if anyone has a question just send me a message and i'll be happy to assist.

easy job and i saved about $70 over what i'd have paid for a specialty module from the bike shop.


tail light conversion
















i've included these pics. the one withe the lights on is what it looks like when i apply brakes. otherwise they're off or function as turn signals. when the brakes are applied the opposite side functions as brake light wile you turn signal works normally.

Thats pretty sharp.... I also have a fear of getting run over from behind and lately in Vegas that seems to be a trend... 2 incidents in the last month alone... that i know of.

I was thinking of just adding a license plate Brake lite (LED type) and have one of the brake blinkers wired in... the type that blink the brake light for 10 seconds then go SOLID. i also added those super black reflective strips to the swing arm and the back of the riders pegs so other might see me..

I like this idea. i wonder if maybe you could solder in 3 bigger amber LEDs in the middle to have turn signals in yellow and BRake lights in red to the signal lamps them selves. it would be 1 more wire. I find the bright amber really catches peoples attention when using them.
