Advanced optics disperse light so efficiently the lens illuminates fully, with no hot spots or dead zones, regardless of viewing angle.
Optics are molded on the underside of the lens, leaving the exterior surface smooth for cleaner, brighter lights in dirty environments.
Flush mount lamps with protective recessed lens design are less likely to be damaged.


Pin connections are insert molded into the housing eliminating a source of moisture.
The 30-degree angle of our space-saving plug housing allows for easy installation and reduces stress on the wire.


No potting material behind the PCB to reduce risk of heat build-up in the light assembly, which can shorten the life of LEDs.
Over-molded locking tab for secure wire attachment.
