Designers at MotoTrix Inc., Deephaven, Minn. (, felt they had a winning idea on their hands with their Light Buster utility and backup light for SUVs. Unfortunately, they were having difficulty making it rugged enough to survive the often-demanding environment. After teaming with Minnesota Rubber QMR Plastics, Minneapolis (, however, the light had no trouble working in all weather conditions.

The light uses a sturdy injection-molded nylon housing with a rotating base. An EPDM O-ring makes it easy to turn the base, which switches between operating modes. The O-ring also seals out moisture and dirt. When the light is plugged into standard seven-pin electrical receptacles found under the rear bumpers of most SUVs, the unit works as a backup light or a utility light. Another EPDM gasket makes the screw-on connection between lens and base watertight.
