It’s a bright taillight…until you hit the brakes. Then, it flashes four times fast—pauses—three flashes a little slower—pauses—two more real slow, and it’s on full time as a stop light. The entire flash/pause sequence takes 4 seconds and repeats each time you re-apply the brakes. This complex pattern is commonly and intuitively recognized as a deceleration warning. The bulb’s reliable digital electronics are all contained inside the bulbs base. Choose from widely available, easily replaceable “G-4” halogen bulb version (easy to carry spare bulb is also included), upgrade to long life LED option, or select the dual ballast CAN-bus compatible model for most modern BMW's. Fits standard 1157 dual filament brake/taillight bulb sockets. Legal disclaimer: May not be approved for use in all states.
