Does this require any wiring modifications?

No—it plugs directly into your factory center brake light connector. If your vehicle still has the original harness, installation is purely mechanical: remove the old light, bolt this one in place, and connect it.

Will this work if my factory brake light housing is damaged?

This assembly is the light itself, not the housing. If your center brake light housing is cracked or missing, you'll need that repaired or replaced separately before installing this unit.

How much brighter is the LED compared to the original?

LEDs respond and illuminate instantly with noticeably higher intensity than incandescent bulbs, making your brake activation more visible to drivers behind you. They also maintain consistent brightness throughout their lifespan without dimming over time.
