Do these lights require any wiring modifications?

These mount at factory side marker locations, so they tie into your existing marker light harness — no custom wiring needed if your vehicle came equipped with markers originally.

Will the clear finish yellow or cloud over time?

Clear polycarbonate can cloud with UV exposure and road chemicals over years of use. Regular cleaning helps, but some fading is normal wear on exterior lights.

Do I need to remove the bumper to install these?

Bumper removal depends on your vehicle's design — access from underneath or wheel well is often possible without full removal, but your service manual will confirm the fastest route for your specific model.
