Do I need to run new wiring or splice into my headlight circuit?

The switch is included and designed to integrate cleanly—no splicing into your factory headlight harness required. Run the harness from the switch to your battery with a standard inline fuse for safety.

Will these mount without drilling or modification to the bumper?

Yes. These mount at factory rocker points on the 4-door Civic—no drilling, no cutting, no permanent changes to your bumper or bodywork.

What if one of the H11 bulbs burns out after I install it?

H11 bulbs are a standard automotive size sold everywhere—any auto parts store or gas station carries replacements. No special ordering needed.
