The Optronics Fusion line of LED lamps offers 4" round and 6" oval formats of the original 9" combination stop, tail, turn and backup lamps. The two-in-one LED lamps fit in standard 4" round and 6" oval lamp holes and come with grommet- and flange-mount models. Fusion 4" round lamps are also available with the company's GloLight technology. The original 9" surface-mount lamps come with hardwire connectors, while all recessed versions are available with either PL-3 or weathertight connectors. All Fusion lamp lenses and housings are made of polycarbonate material. The lamps employ a solid-state, surface-mount device design that protects the electronics against moisture, shock and vibration, and each lamp comes with a lifetime warranty.
