Do these lights use the existing bulbs from my factory corners?

The assembly is designed as a direct replacement at factory mounting points. Confirm your existing bulb type before install — you may reuse them or swap to new units depending on your preference and compatibility.

Will I need to drill into the truck bed or fender to mount these?

No drilling required. These bolt directly into the factory corner light locations using existing holes and fasteners.

Can I install these myself with basic hand tools?

Yes. Removal of the old corners and bolt-in installation is straightforward — you'll need a socket set and possibly a panel removal tool to access the fasteners without damaging trim.
