Looking for a lightweight, helmet mounted, HID light? The Enduro Lith is for you! New for 2008 the Enduro Lith uses the same high-powered HID headlamp previously found on the Firestorm, combined with a new ultra light, compact Li-Ion battery weighing 221grams. This helmet mounted system gives you the power of an HID without the weight of traditional NiMH batteries. Charge time is a quick 1.5 hours and run time is 2:15.
