Daytime Running Lights + Switchback LED’s

The DRL will not work in "Auto" unless the headlights are on also which would defeat the purpose.

If you want true DRL you would need to run power sourced by a relay powered by ignition-on that kicks off when it gets power from the headlight circuit. Very do-able but not what I was going for. I actually like running my parking lamps during the day in the rear for added visibility and saw no reason to go through the trouble of wiring DRL only!

Did that answer your question or did I miss the point? I'm not the brightest werewolf in the horror industry...
