LEDs are waterproof, sealed in a durable silicon strip, flexible, and very dependable. Unlike halogen rock lights that draw high amps, LEDs only use milliamps, so the draw on your battery and alternator is minimal. You will be amazed at how much light the LEDs actually put out. They look small, but perform big. This is the perfect light for your crawler or buggy on those night wheeling trips or just when you need some light under your rig for a trail repair.
