Provide a rugged, discreet structural foundation for your vehicle's safety lighting with the Truck-Lite 21721 Super 21 Rectangular Bracket Mount. Explicitly engineered to house industry-standard rectangular 21 Series clearance and side marker lamps, this heavy-duty black base mount is a preferred choice for commercial freight trailers, dry vans, reefers, box trucks, and heavy-duty utility fleets.

Molded from premium-grade, impact-resistant black polycarbonate, the Truck-Lite 21721 delivers a professional, clean look that blends seamlessly with dark trailer frames, vocational bodies, or aluminum skin panels. Its low-profile, high-strength design accelerates vehicle assembly and cuts down on fleet maintenance downtime by allowing compatible Super 21 lamps to quickly snap directly into place, creating a reliable and secure housing channel.

Note: This item consists of the raw mounting bracket component only (non-kit) and does not include an integrated wire harness or lamp assembly.
