head light help

[smoke118]

Hey does any one know if the 2001 GMC truck head lights work off of a ground side switch or power side? I would like to put some wig wag police lights on my truck.

the headlamp switch on a 01 switches power to the headlamp relay. its a power switch.

The switch just supplies control voltage to trip the relays located in the underhood fuse box.
maybe you can access what you need there.
