Gemini DUO LED Light System (4 Cell)
1500 Lumen Headlamp

peter Good light for helmet, easy set up and nice beam pattern for road rides day and night.
Mr Antill A fantastic light set up, unbelievably bright on full as much as a car, too much in fact, but not too much to blind on coming traffic when used on the road. It comes in a neat zippered box with all accessories. Very impressive.
