I just ordered some EBAY cubes for my rear reverse. I can't decide if I want them to run off the backup lights or switched. Anyone want to set me straight?
Do both. I have mine wired up to a DPST switch. So normally they operate with the reverse lights every time I back up, but I can flip a switch to override them and turn them on whenever I want (usually when hooking up my trailer in the dark). You could use an upfitter and a relay to do this, but I put the switch in the bed since I figured 99.99% of the time I'm using them for reverse lights, and the 1% of the time I need the aux light when I'm not in reverse, I'm standing at the back of the truck anyway and want to be able to power them without the key on.
