Abstract: A signaling system for mounting to an exterior surface of an emergency vehicle is provided. The signaling system includes a light bar and a pair of mounting feet. The light bar can include a plurality of signaling devices supported on and distributed along a base member and enclosed by a cover. The light bar can be secured to the mounting feet via a plurality of fasteners. The mounting feet can be connected to the emergency vehicle via roof straps. Each mounting foot can include a base, which can have a support portion, a contoured portion, and a pair of compartments; a pair of seals associated with each compartment; a pair of covers, which can be translucent, removably mounted to the base to enclose the compartments; and a roof strap secured to the base. Each compartment can house a signaling device, such as a lamp assembly.
