I'm flat-bedding the truck, and at the current moment, have a set of trailer lights in the back.

Since the truck ('86) has a seperate turn signal and brake light, I can't get the trailer lights to function as both. Right now I just got a couple of clearance lights to funtion at signals.

Anyways, how can I convert the wiring over so I only need one light that functions as both brake light AND turn signal (like most cars do).

Thanks for the help!

 

One option is to get a trailer wiring light conversion box.

 

PERFECT! Don't know why I didn't think of that.

Thanks much!

 

or you can change the sockets in the tails and use 1157 bulbs instead of 1156's. or change the tails to a STT type. (STOP TAIL TURN). I don't know what kind of trailer light you have now though. You need ones that have 3 wires not 2. 1 will be a common the other 2 will be switched.
