    • 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.
