Key Feature

Product Details

The RN 100 TL is movement-sensitive light with a built-in accelerometer that goes into an attention-grabbing burst mode when you brake or slow down. Whether you're riding in broad daylight or complete darkness, the RN 100 TL offers constant, flashing, and smart light modes to keep you safe and visible. A single press of the button selects the brightness level and the flashing modes, double press cycles through the pattern options and a long press turns the light on or off. The light remembers the last mode used.

The status LED on the light turns red when the battery gets low, and when about 20 minutes are remaining it will automatically switch to a low-powered flashing mode to help ensure you have light until you get home.
