X3B Brake Light | Colorado

Want a brighter third brake light that can also help you see into the bed?

The Morimoto X3B replaces the factory third brake light on listed 2015-and-newer Chevrolet Colorado applications. It reuses the original mounting points and connects through the included plug-and-play adapter harness, so the install is designed to need no modifications. The red/white LED module also adds bed-light utility after dark.

Who this is for

• Owners of a compatible US-spec 2015+ Chevrolet Colorado
• Drivers looking for a third brake light with an added bed-light function
• Customers who want to choose whether to include the optional rapid-flash module

Who this is not for

• Vehicles outside the listed Colorado fitment or non-US-spec vehicles where compatibility is unconfirmed
• Customers expecting the rapid-flash module in every option, select the Rapid-Flash Mod option if wanted
• Anyone looking for a separate cargo-bed lamp instead of a third brake light with bed-light functionality

Choose your option

• Rapid-Flash Mod: includes the plug-and-play flasher (X3B01)
