Exposure Lights

The Diablo scores on every level, high power, light weight and packed with technology. New TAP capability means that a simple tap to the light will change the mode. This new functionality enables the Diablo to be best used as it is intended, on rapid descents at Gatcombe Park. The Diablo has again been upgraded, now pushing out 1300 lumens it’s perfect for fast descents and small enough for a discrete powerful addition to a road bike. OMS allows burntime adaption to ensure that you’re using the light to its max while ITM keeps it running at full efficiency.
