Do these lights require any wiring modifications?

No. These use factory wiring connectors, so they plug directly into your existing bumper harness. No splicing or adapters needed.

Will the smoked lens still pass inspection?

Side marker lights are amber lights, and smoked housings typically pass DOT visibility standards. Check your local inspection rules before install to be safe.

Do I need to remove the entire bumper to install these?

Not necessarily. You may be able to access and swap them from under the bumper or remove just the corner trim pieces. Test-fit the housings first to confirm your access point.
