  • Patent number: 7758220
    Abstract: An in-ground inspection lighting system, particularly an in-ground inspection lighting system for underside of vehicles including an elongated, embedded light transmitting optical fiber in a polymeric mass, remotely energized, and placed into a pre-determined channel formed in a medium such as concrete or asphalt, whereby the embedded embodiment does not protrude from the channel and is essentially flush mounted in the medium. Alternatively, an in-ground inspection lighting system including, an elongated embodiment of linear light emitting diode assemblies embedded in a polymer mass and placed into a pre-determined channel formed in a medium such as concrete or asphalt, whereby the embedded embodiment does not protrude from the channel and is essentially flush mounted in the medium. The linear embodiments to provide a steady, uniform flood of light up to the underside of a vehicle to be inspected.
