How to Have Trailer Clearance Lights That Also Flash with Turn Signals

Question:

Hi, I was wondering, is it possible to make certain clearance lights ie: center lights on my trailer blink with the turn signal? My trailer has the rv 7 plug on it, if that makes any difference.

The only way to have clearance lights on your trailer that also flash with the turn signals is to have multi-function light assemblies that feature a separate wire for each the running lights and turn signal circuits. If your existing clearance lights only have 1 power wire then you won't be able to wire them so that they accept both the turn and running lights circuit and function properly.

Something like the Optronics LED Clearance and Side Marker Light # MCL32ATB would work well for your application. This LED light is designed to serve as both a clearance/side marker light and turn signal with its 3-wire pigtail. One wire will go to the running lights circuit, one will go to the turn signal circuit, and the other will be for ground.

I have attached a short video review that you can check out as well.
