No other led light offers the same level of all-round visibility as the tl1100. Cateye’s Opticube technology is combined with 10, yes 10, ultra bright red LED' for unparalleled brightness. 6 leds face backwards and 2 are positioned on each end - each row can be independently controlled through 4 different modes for a total of 16 different combinations. If ever a light was worth the expense, this is it.
