SpeedTech Lights support FAQ

Common questions about manuals, registration, and support for this brand.

  • 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.

  • What should I do if my product malfunctions?

    If you experience a malfunction, contact STL Customer Service immediately at 800-757-2581 for troubleshooting options or to initiate a warranty or service claim.

  • Can I replace the lenses if they yellow over time?

    Yes, replacement lenses can be purchased by contacting SpeedTech Lights Customer Service.

  • How do I sync my STL ELD device?

    Plug the ELD device into the vehicle's diagnostic port. The device will automatically start syncing with the Engine Control Module (ECM) and the STL ELD application on your tablet once the app is launched and logged in.
