Do I need any special fasteners to mount this?

Mounting hardware is not specified in the product data — test-fit before committing to fasteners or adhesive. Your factory brake light mounting points should guide installation, but confirm compatibility with your truck's bed design first.

Will I need to prep or seal around the lens?

The smoked finish is applied to the lens; no additional painting is required. Once installed, a quality silicone sealant around the mounting edges will protect against water intrusion in the truck bed area.

Does this unit include bulbs or is it all LED?

This is a fully integrated LED assembly — no separate bulbs to purchase or install. The LED is built into the unit.
