Hey guys I was wanting to make my marker light dim when turn signal is bright, is there a switch that I can splice in to cause that?

 

So the corner light is too bright? Or you just want to make it dimmer to make the turn signal more visible?

Back in the 70's? I think the Chevy used to blink them off while the turn signal was on. That would be easy to do, just tie a relay into each marker light. Have it fired by the turn signal wire. Using the NC contacts, they would open when the relay turns on, thus turning the marker light off when the turn signal is on.

 

You can use a relay to cut the power to the marker light when the turn signal is on but making it just dim a little will require some electronics to control the voltage.

 

Why......?
