WORK TRUCK SHOW -- Optronics International is unveiling its new STL68 Combo Lamp at the 2014 NTEA Work Truck Show in Indianapolis. The 9-inch oval combination LED stop, tail, turn and backup lamp easily mounts to the surface of a vehicle, and at only half an inch thick, has the low profile of a through-hole-mounted lamp.

Traditionally, vehicles have been fitted with separate 6-inch stop, tail, turn lamps and 6-inch backup lamps. Every individual lamp required a mounting hole in the vehicle body panels, frame posts, docking plates or gussets. Each resulting lamp cavity can reduce structural integrity and provide a path for the intrusion of moisture and other contaminants.

Today, stop, tail, turn functions are often performed by LED lamps, while backup lighting has remained largely the realm of incandescent lamps, due to cost and other factors. Optronics’ new STL68 nine-inch oval Combo Lamp is designed to give users the functionality of two lamps for the price of just one. Additionally, because the lamps are all LED, they are more dependable and thus safer than incandescent lamps.

Mounting the new STL68 9-inch oval Combo Lamp requires only a small half-inch 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. Because the mounting process is less invasive, a vehicle’s structural envelope can now remain largely intact.

The new STL68 9-inch oval Combo Lamp meets all FMVSS 108 photometric requirements for visibility and safety. 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 their 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 Combo Lamp is expected to begin shipping in the second quarter of 2014.
