Do these lights tap into my truck's factory wiring?

These are designed to integrate with your existing towing mirror circuit. You'll need to verify connector compatibility with your truck's electrical system before installation — connector type is not specified in the product data.

Will these lights interfere with mirror folding?

These mount flush to the towing mirror assembly and are designed for that application, but test-fit them before finalizing installation to confirm clearance with your specific mirror design and any accessories you run.

Are bulbs included in this kit?

Bulbs are not included — you'll need to source the appropriate replacement bulb for your mirror light assembly separately.
