• How do I clean my STL light bar?

  Use only water (H2O) with a soft cloth to clean the outer body and lens of your equipment. Never use a pressure washer or take the lights through an automatic car wash, as high pressure and chemicals can damage the seals and lenses.

• Where should I mount my light bar to avoid interference?

  Light bars should be mounted a minimum of 12" - 34" away from radio antennas to prevent electromagnetic interference. Do not power the equipment from the same circuit or share a grounding circuit with radio communication equipment.
