Light bar
First Claim
1. A light bar for mounting on an emergency vehicle comprising:
- a housing having at least one set of upper and lower shells joined at a seam;
at least one tray in a recess of the lower shell of the housing;
a plurality of cells formed in the tray, each for receiving and fastening components of a light fixture such that the cell provides a functioning light source when it is equipped with the components;
the light fixtures received in the cells of the tray defining a lower tier of lights substantially disposed along a first horizontal plane;
an upper tier of lights positioned above the lower tier and substantially disposed along a second horizontal plane;
a top of the tray being at a height that substantially matches a height of the seam formed where the upper and lower shells join, such that the lower tier of lights is below the seam and the upper tier of lights is above the seam.

Abstract
A light bar for mounting on an emergency vehicle has a modular construction using trays for mounting lights. The trays are integral members having cells formed therein for receiving components of light fixtures. The light bar has two lighting tiers. The lights on the lower tier are received in the cells of the trays. The tops of the trays provide a platform for mounting lights on the upper tier. Alternatively, the upper-tier lights may be mounted on the upper shell of the housing of the light bar. Snap-fit fasteners are formed on the trays for mounting components of the lights. In one configuration, the light bar includes a speaker which has a driver mounted inside the light bar housing and a horn which fits in an opening in the housing and is coupled to the driver for transmitting audio signals.
