Title: Signaling lamp having led light array with removable plastic lens

Abstract: A signaling lamp allows improved serviceability and dependability. The lamp includes a light source, housing, backing and removable sealing mechanism. The housing includes a casing for coupling the housing to the backing, and a lens with a plurality of convex nodes along the interior surface for more efficiency collecting light from the light source. The modular structure and a pigtail socket achieve improved serviceability by allowing components to be individually replaceable and by increasing connectivity. Gaskets and an o-ring in conjunction with an o-ring slot formed in the backing of the lamp enhance sealing of the components. A heat sink on the backing operates to remove heat from the interior of the lamp. A current draw circuit and LED-based light source reduce the current draw to allow the lamp to use the standard battery from the primary vehicle as a power source.
