The B6 LED brake light was purpose built to create the most amount of light from the smallest, most low-profile, housing possible. Six 1.0 watt LEDs generate all the added visibility in a sleek, easy-to-mount device. With a simple two-wire brake circuit, the B6 is the optimum brake light to add to the CANsmart™ Controller for a true plug-n-play installation. If a CANsmart™ Controller is not available for your vehicle the B6 can still be installed to add a super bright auxiliary brake light. Note that running light, flash patterns, and deceleration activated "auto brake light" functionality is only available when used in conjunction with the DENALI CANsmart™ Controller.
