Do these lights connect to my existing wiring or require custom harness work?

The integrated switch comes pre-wired with a harness designed for direct connection. You'll plug it into your factory fog light circuit if one exists, or route it through the fuse panel — either way, no splicing required.

Will the switch work with my headlights on, or does it operate independently?

The switch can run on its own circuit or sync with your high beams depending on how you wire it. Both configurations work — it's your choice based on how you want to use them.

What if I need to replace a bulb down the road?

Bulbs are standard 881s — grab replacements from any auto parts store. The assembly is designed for easy access without disassembly.
