Do these mount using the factory bolt points, or do I need to drill the frame?

These use your Charger's factory mounting points — no drilling or new holes. Bolt them in place and wire the connectors to your existing harness.

Will the clear corner sections yellow or cloud over time?

Hard panel construction resists UV damage and road salt better than older sealed units, but clear plastic does age with sun exposure. Covers or garaged storage will extend clarity over years of daily driving.

Are bulbs included, or do I transfer mine from the factory headlights?

Transfer your existing bulbs and connectors from the original housings — bulbs ship separately or are assumed to be in your current setup.
