Patent ID: 7905640

Claim:
An emergency light for a vehicle comprising: a housing having lenses for transmitting light from an interior of the housing; one or more circuit boards within the housing, each circuit board having a planar surface extending toward two or more of the lenses for supporting two or more light beam assemblies such that each assembly is aligned with one of the lenses; each of the circuit boards having; one or more connectors mounted for electrically communicating with the two or more light beam assemblies by way of electrical connections fabricated on the circuit board; and a first set of patterns of alignment keys for registering the two or more light beam assemblies to the circuit board so that the light beam assemblies are fastened to the circuit board at positions predetermined by the patterns; and a second set of patterns of alignment keys in the housing for positioning each of the circuit boards within the housing at a predetermined location that automatically aligns the two or more light beam assemblies fastened to each of the circuit boards with the lenses of the housing when the circuit boards are fastened to the housing, thereby enabling each of the lenses to cooperate with a corresponding aligned light beam assembly to broadcast a light beam alerting observers of the vehicle to an emergency condition.
