Need help with a Dodge Charger question.

I'll say it again: no need for relay with LED headlights. A 60w LED draws about 1/2 amp. That is a mere 3 amps for a 4 headlight car & 2 amp for a 2 h'light car.
The saving in voltage drop by using a relay, & all the extra trouble of wiring it up, would be sooooooooooo minimal that you would not see the difference in light [ lumens ] output.
Incandescent headlights, different story: typical 35w low beam/55 w hi beam. Four headlights would draw 24 amps, so well worth the trouble of fitting relays.
