The Optronics HD 500 Series of LED stop, tail, turn lamps offer a three-dimensional lens feature with a raised linear focal point in the center. Both the 4" round and 6" oval lamps are engineered with an 18-diode configuration, creating a bright perimeter of LEDs surrounding a convex central feature with a contrasting illumination pattern. All HD 500 Series LED lamps meet FMVSS 108 and SAE photometric requirements for visibility and safety and come with a lifetime warranty. The lamps use solid-state, surface-mount device (SMD) technology to resist moisture, shock and vibration. The lamps will be available with standard PL-3 and Weather Tight termination and will interface with existing harness systems to assist retrofitting.
