The Optronics LED SuperLamps are designed to resist damage to internal electrical components and offer a coating and bonding system that protects the exterior and housing. According to the company, the lamps are immune to transient voltage, electromagnetic interference and electrostatic discharge. The lamps feature solid-state, surface-mount device technology to allow the LEDs to function even if the unprotected circuit board is submerged in water. The protective coating resists several automotive fluids. The lamps meet all FMVSS 108 photometric requirements for visibility and safety, and each lamp will come with a lifetime warranty. The company offers 4" LED stop/tail/turn lamp as well as red and amber lamps in 4" round grommet-mount and 6" oval varieties.
