LUX LED Backups have been uniquely designed to replace dimmer stock bulbs and fixtures with a brighter LED based bulb replacement system.  In addition to being brighter than stocks, LUX LED Backups offer a nice daylight color, and make it easier to see when backing up your car. Our focused-beam pattern also offers tighter light dispersion than  than wide light output stock products. And, our lights even do a self-check during start-up, emitting a 1-2 second pulse.
