Can the parking light wire be hooked up to another source?

Question

I have a 2010 Ram 2500 with gas engine. I have a set of Rock lights underneath my truck for an awesome look when it is parked.  Can I hook up the Signal wire from the 20 pin harness of a EVO-CHRT4 to these lights instead of to the parking lights?  these Rock lights draw 4.5 amps. Could I connect the signal wire to the ground of these rock lights?

Answer 1

I don't see why you couldn't. Those would flash as supposed to your parking lights.
