Every bike has a license plate. Every license plate has bolts. The Denali LED Auxiliary Brake Light cleverly connects to these fasteners to offer an additional brake light for increased visibility. A Denali B6 Light is dual intensity meaning it'll function as a running light and brake light, mirroring the existing brake light functionality of your bike. With the average taillight only being a few inches tall, an additional brake light mounted below your license plate dramatically increases the total footprint of rearward illumination.
