Hi. I hope someone out there can help me on this one. I have a aftermarket black box that converts my rear turn signals on my 1990 R100RT to running lights and stop lights. It makes the turn signals running lights all the time and then they become stop lights when the brakes are applied, all the time allowing the turn signals to operate normally. I have had this for so long I can't remember what brand they are. My wife loves them and wants them on her RT. The device is a "black box" with about eight wires coming out that splice into the turn signal and brake light wiring harness. The "box" is about 3" x 3" x 1/2" and is a completely encapsulated unit that zip locks to whatever is convienient. I sure hope someone can identify this device because she has taken to trying to steal mine Thanks for your help, Bruce.
