3.1875 Inch Red Round DOT Bolt-On Reflectors

Boost your safety profile and stay road-compliant with our 3.1875-Inch Red Round DOT Bolt-On Reflectors—a rugged, reliable visibility solution for trailers, trucks, agricultural equipment, and commercial rigs. Designed to meet Department of Transportation (DOT) safety standards, these red reflectors are an essential component of any vehicle or trailer setup that operates in low-light or night conditions.

Whether you’re outfitting a new trailer, upgrading an existing fleet, or performing a safety check before your next haul, these bolt-on reflectors provide long-lasting visibility and peace of mind.

Built for DOT Compliance and Enhanced Safety

Designed with Federal Motor Vehicle Safety Standards (FMVSS) in mind, this red reflector delivers strong, bright reflection that’s visible even at wide angles. The 3.1875-inch diameter face provides ample surface area to alert approaching drivers of your presence on the road or at a work site—day or night, rain or shine.

DOT regulations typically require red reflectors at the rear and rear-sides of trailers or large vehicles to enhance visibility and outline the vehicle’s footprint. These reflectors help prevent accidents by making your rig easier to see from multiple directions, especially in poor lighting conditions or during roadside stops.

High-Visibility Red Reflective Lens

The red lens is precision-molded from optically enhanced polycarbonate, engineered to maximize reflectivity from a wide range of angles. Even when headlights hit at a glancing angle, these reflectors catch the beam and send it right back—alerting other drivers to your vehicle’s position before they get too close.

Unlike stick-on reflectors that lose adhesion or fade, these bolt-on models remain securely fastened and bright for the long haul. They are ideal for marking the back end of enclosed trailers, flatbeds, cargo haulers, or agricultural equipment operating near roads.

Rugged Bolt-On Installation

This reflector is designed for permanent installation using the two pre-drilled mounting holes. Its bolt-on construction ensures a secure fit on virtually any metal or composite surface—trailer frames, rear bumpers, toolboxes, fenders, and more. Installation is quick, easy, and doesn’t require wiring or specialized tools.

Use standard screws or bolts (hardware not included) to mount these reflectors wherever visibility is critical. Because they are mechanical rather than adhesive, they stay in place through vibration, weather, and heavy-duty use.

Built to Withstand Harsh Conditions

Whether you’re hauling through rain, snow, heat, or mud, these reflectors are built to go the distance. The UV-stabilized polycarbonate lens resists fading and cracking from prolonged sun exposure, while the sealed body keeps out moisture and road grime.

These reflectors perform reliably in:

• Commercial trucking environments

• Agricultural and farm operations

• Construction sites and utility trailers

• Long-haul transport and delivery routes

• Off-road or seasonal equipment storage

Once installed, they require virtually zero maintenance—just solid visibility when you need it most.
