Deceleration Sensing LED Tail Light Bulb

Integrated deceleration-sensing technology illuminates this tail light bulb even when you downshift or slow without applying any braking force. Automatically brightens alerting traffic behind you of reduced speed while decreasing the chance of a rear-end collision. Apply brakes and it functions just like your standard brake light system. Patented design integrates auto-recharging, self-powered capacitors with self-activating technology and long-life LED lamps. Fits most motorcycles, replacing any standard 1154 (6 Volt) or 1157 (12 Volt) type bulb (with the exception of rear-loading lamps). CAN Bus compatible. Rated to last up to 5 years.
