Ford F150 (15-19): Recon 3rd Brake Light Kit is factory unsealed. This allows you to easily colour match the inside bezel paint and then seal the lens using a permeatex silicone.
The reason these are offered unsealed in the chrome model is because the lens on the chrome units are clear. Using a smoked unit with a smoked lens would make painting the inner bezel pointless.
ALL FACTORY UNSEALED 3RD BRAKE LIGHTS ARE SOLD WITH NO WARRANTY AND CANNOT BE RETURNED TO US. PLEASE MAKE SURE YOUR ARE ORDERING THE CORRECT PART BEFORE PURCHASING.
