Grommets, Plugs & Harnesses

UnitedBuilt’s Grommets, Plugs & Harnesses collection includes lighting installation components used to mount, connect, and service vehicle lights on water trucks, service trucks, commercial vehicles, trailers, and equipment. This collection includes rubber grommets, light plugs, pigtails, connectors, wiring harnesses, and related lighting repair components.

These parts are commonly used with DOT lights, marker lights, clearance lights, stop/turn/tail lights, backup lights, work lights, and other vehicle lighting assemblies. Proper grommets, plugs, and harnesses help protect lighting connections, support clean installation, and make future service or replacement easier.

UnitedBuilt stocks and distributes Peterson Manufacturing grommets, plugs, pigtails, and harness components used in water truck lighting systems, fleet maintenance, commercial vehicle repairs, and equipment upfits.
