Simply the best value in high output bike lights we have ever seen. This is the big brother of the True 150, and is essentially the same light, besides the OVER DRIVE mode that puts out a blinding 250 lumens. It has 5 modes, OVER DRIVE, high, med, low, and blinking. The battery is in the light, no cords. Weighs in at only 150 grams. It has a light up battery life indicator that switches from blue to red when the light is running low. USB and wall charger, Included! Helmet mount, Included! Handle bar mount, Included! Life time warranty on the light. Year warranty on the Li-Ion battery. After you use your light a ton and the battery starts to loose its charge, the replacement battery is only $25. Dang, that's value!
