The Optronics Combo Lamp, No. STL68, offers two lamps for the price of one. The 9" oval combination LED stop, tail, turn and backup lamp easily mounts to the surface of a vehicle. Mounting the STL68 requires only a 1/2" egress hole for wiring and four small mounting holes for rivet or screw fasteners. The low-profile lamp fits snugly to the surface of the vehicle for a clean, finished look. Lenses and housings are made of tough polycarbonate material that is sonically welded. The lamps employ a solid-state, surface-mount device design that protects electronics against moisture, shock and vibration, and each comes with one-diode lifetime warranty protection that will replace the lamp if even one diode fails. The new STL68 nine-inch oval Combo Lamp meets all FMVSS 108 photometric requirements for visibility and safety.
