Truck-Lite 97820 6-Inch Round Black Steel Universal Convex Blind Spot Mirror Head Assembly (Includes L-Bracket Mounting Hardware, Replaces Signal-Stat 7070/7071/7072)

Eliminate dangerous roadside blind spots and secure an expanded wide-angle panoramic view with the commercial-grade engineering of the Truck-Lite 97820 6-Inch Round Convex Mirror Head. Specifically designed as a highly reliable universal safety helper mirror for commercial tractor-trailers, inner-city delivery box vans, vocational dump trucks, and municipal utility vehicles, this premium spot mirror delivers clear coverage of your vehicle's lower flanks and immediate wheel wells. By keeping your drivers continuously aware of neighboring traffic and low-clearance lane hazards, this assembly directly supports your fleet’s compliance with strict FMVSS 111 commercial rearview safety visibility mandates.

Avoid the structural failure common to cheap plastic imitation backings that fracture under extreme weather or warp under high-speed highway wind resistance. The 97820 features a heavy-duty, stamped carbon structural steel backing shell treated with a premium matte black finish. This all-metal casing provides maximum physical protection against flying road gravel, stone chips, and severe industrial debris. For sustained, distortion-free optical clarity over millions of miles, the high-fidelity curved convex glass lens is cushioned within a shock-absorbing vinyl perimeter gasket, creating an airtight barrier against moisture tracking while dampening continuous chassis tremors to prevent mirror clouding or edge peeling.

Integrating this blind spot mirror into your current frame layout is exceptionally fast and simple. The mirror head connects via an internal, 5/16"-24 female adjustable threaded ball stud (0.313 in. mounting connector diameter). This specialized joint allows drivers to pivot, swivel, and lock in the exact perspective tracking angle required while actively protecting the fastener against thread slippage under intense vibration loads. For total field convenience, each mirror module comes equipped with a black-coated steel right-angle L-bracket mounting accessory out of the box. This makes it a highly versatile replacement head that can be mounted universally on either the driver or passenger side cab door loop frames, tripod bars, or fender pillars.

This universal side-view mirror acts as an immediate, exact-fit direct field replacement for legacy Signal-Stat 7070, 7071, and 7072 series black profiles, providing private fleets and maintenance teams with an affordable drop-in solution to restore total frontend visibility.
