Since 1992 SolarOasis has designed many OEM applications that use LEDs. A more recent safety application is the RainRacer accident avoidance light for race cars.
High brightness LED (HBLED) technology provides race cars the visibility they need in rain conditions.
The RainRacer features extremely low energy consumption, wide input voltage range, and visibility of hundreds of yards in dense rain.

If your favorite racing supply store does not carry the RainRacer, ask them why not.
