Will these mount to the factory bumper without drilling?

Yes. These use factory mounting points on the bumper — no drilling, no brackets, just bolt-on installation.

Do these require wiring, or do they tie into existing harnesses?

Mounting method and electrical integration are not specified — test-fit first to confirm harness access and mounting clearance before committing to any permanent installation.

Can I paint the black housing to match my bumper color?

The housings arrive in black finish. Test on a hidden section first if painting — confirm adhesion on the plastic before coating the visible assembly.
