High Intensity Discharge lamps (HID) are amazingly bright. HIDs push out 2-3 times more light than halogen lamps, with a visual area that is longer, wider and bathed in intense white light - perfect for all high speed riding.
For the rider who wants the versatility and safety of using two separate headlight systems together for a more intense, flexible light positioning - the Halogen/Photon 19 has it all covered.
