You're a mile from home, unsure of how much juice your bike light has left. It's an uncomfortable situation, and one that the Serfas ULSA-8 Orion Blast Front Bike Light aims to solve. On top of a crazy amount of candlepower blasting from its small size, this light has a tiny speaker to send you a warning that you have ten minutes left at your current level. The choice is now yours: switch to a lower lighting setting for some more time, or put the hammer down and race home. We'd suggest the latter.
