Do I need to drill into my roof to mount these?

Mounting method depends on your roof style and existing bars or rails. Test-fit the assembly first — many vehicles with roof racks or factory crossbars use existing mounting points. Have fasteners and any reinforcement plates ready before committing.

The supplied switch routes power independently — run the wiring to your battery or fused auxiliary power source. This keeps fog light operation separate from your headlight circuit and protects both systems.
