LIGHT BAR AND METHOD FOR MAKING
First Claim
1. A light bar comprising:
- at least one circuit board with keys in its surface that assist attaching the circuit board to two or more light beam assemblies such that the keys pilot the attachment of the one or more light beam assemblies to the circuit board to register each of the one or more assemblies on the circuit board at a predetermined position;
each of the one or more light beam assemblies including keys complementing at least some of the keys in the at least one circuit board such that engagement of the complementing keys registers the assembly at the predetermined position on the board; and
a housing including keys complementing at least some of the keys in the circuit board such that engagement of the complementing keys registers the circuit board to the housing so that each of the one or more light beam assemblies attached to the circuit board is automatically aligned with lens in the housing.

Abstract
A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.
