Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
119 words
A signaling lamp comprising: a light source; a housing; a backing having a plurality of risers suspending the light source between the housing and the backing such that air surrounds the light source, the backing including a longitudinal surface defining an o-ring slot; and a removable sealing mechanism for coupling the housing to the backing such that the light source is enclosed by the housing and the backing, the sealing mechanism including a plurality of sealing screws for coupling the housing to the backing, a sealing gasket disposed between the housing and a lateral surface of the backing such that the sealing screws pass through the sealing gasket, and an o-ring disposed between the housing and the o-ring slot.
Claim 2
Dependent Claim
