US Patent 7854531 Bridge seal for a warning light assembly

The disclosed bridge seal includes a substantially rigid bridge component and flexible gutter seal arranged to span the openings between adjacent housing modules of a modular warning light assembly such as a lightbar. The bridge seal physically connects the adjacent ends of base and dome components to each other and defines a fluid flow channel to guide water away from the area between housing modules. The disclosed bridge seal integrates discrete housing modules into a connected weather resistant enclosure having a longitudinal path for control and power distribution conductors extending the length of the lightbar.
