The B6 LED brake light was purpose built to create the most amount of light from the most compact, low-profile housing possible. Six 1-watt Light Emitting Diodes generate improved visibility with minimal bulk. Newly updated to operate as both a brake light and running light, the B6 provides enhanced functionality on conventional motorcycles as well as those that can use the advanced features of the CANsmart Controller (sold separately). Note that flash patterns and deceleration activated “auto brake light” functionality is only available when used in conjunction with the DENALI CANsmart Controller.
