The Work Behind the Lights
Professional Vehicle Lighting and Upfitting Services.
At Guardian Lighting & Sound, we build and install lighting, audio, and safety systems that work as hard as your vehicles do. From one truck to an entire fleet, every install is clean, labeled, and built to perform on the job.
At Guardian Lighting and Sound LLC, we specialize in professional strobe light installs, safety systems, and custom audio solutions for work trucks, commercial fleets, boats, and ATVs across Upstate South Carolina. Whether it’s emergency lighting, sound upgrades, or full vehicle upfitting, we deliver clean, reliable work using top-tier brands like SoundOff Signal and Feniex Industries. We’re trusted by local companies like Fort Hill Natural Gas Authority and Greenworks Recycling, and we’re proud to help crews stay seen, heard, and fully equipped on and off the road. From a single truck to an entire fleet — or even your weekend ride — we’ve got you covered.
Every vehicle we touch gets the same level of care, precision, and pride — because your safety, style, and performance matter.
