Running wiring for a roof top warning light.

Chances are if you want the roof marker lamps you re going to be running wires. This forum helped me find the wiring but is there an existing hole through the roof say under the marker light to get the wire from the light to the switch connection. This is the best method because it is the shortest distance for the wire to travel and it has the least chance of getting smashed in your. Just got a silverado 2500hd duramax and am trying to wire a cab top magnetic red light for fire and rescue.

When you get the light bar properly mounted to your roof and all the holes are sealed to become waterproof it s time to run your wiring. These atomic leds are designed to replace your factory lights using the same factory plug and mounting holes and to draw less power from your electrical system while creating a brighter more visible light. The roof light wiring switch that is part of the plow package is not for marker lights. It s supposed to be used for a strobe flashing safety light.

The best way to do this is to drill a new hole in your roof near your roof mount brackets and run the wiring down directly into the cab of the truck.
