What kind of lights would i have to get to match the headlights for the back plate lights? Meaning the same temp or whatever they're rated by?

Anyone know?

 

really no correct answer for that question. all different brands for ie. PIAA, V-LEDS, Superbright all have a different "tint" or shade of temperatures as well as colors. You really just need to try and get most of your bulbs from the same manufacturers to match them up the closest.
