COST SAVING CHEM LIGHT ALTERNATIVE. Made in the USA, this waterproof modular lighting system is unlike any other light on the market. Each LazerBrite consists of 2 independent LED heads & 1 translucent tube. With our reversible head technology, this LB can emulate a red or white chem light, function as a flashlight & marker light simultaneously, separate into 2 lights, or produce a focused spot. Multiple units can be connected to form a longer signal baton. The LB system is a versatile, more effective cost saving alternative to chem lights and the perfect lightweight flashlight for your personal lighting needs. 7 colors, including IR, run continuously for days. Bulbs are visible over 1 mile away. GSA package includes, LazerBrite light pre-loaded with batteries (2 in each head), 1 Mini Glow Dome (turns either LED head into a small area light or lantern) and 1 extra set of batteries (strip of 4 sealed). Patented.
