The 4D Lite Plus is the biggest, brightest, and toughest generator taillight we carry. Four ultra-bright red LEDs, a big reflector, and a powerful standlight make you stand out in a dark street...or a crowd. When you're parked or crowded, the steel rail running across the center of the lens stops any unlucky nudges with a hearty "clang."
-Designed to work with 6 volt dynamo systems (Shimano, B&M, Schmidt) -The "standlight" holds a charge to keep the light going for a few minutes after stopping -Overvoltage protection saves the circuitry and LEDs from frying if the headlight fails -Built-in passive reflectors also satisfy legal reflector requirements, so you can leave the cheap plastic clip-ons at the bike shop
