The Optronics ONE Series LED Lamps are the first low-cost, single-diode alternatives to incandescent lamps, according to the company. The LED lamps meet all FMVSS 108 photometric requirements for visibility and safety. Each lamp comes with a lifetime warranty, and lenses and housings are made of tough polycarbonate material that is sonically welded. The lamps employ a solid-state, surface-mount device (SMD) design that protects electronics against moisture, shock and vibration. Grommet-mount versions of the single-diode 4" round lamps in red and amber, Nos. STL003RB and STL003AB, and 6" oval lamps in red and amber, Nos. STL002RB and STL002AB, are available.
