ABSTRACT:
An emergency signal device adapted for concealed mounting in the roof of a vehicle thereby providing a secret light is disclosed. The device comprises a housing of a generally open-top, box construction adapted to be mounted in an opening in a roof of a vehicle and receiving an emergency signal enclosure that has a top plate having a contour conforming to the roof line of the vehicle and a span sufficient to overlie the peripheral edges of the box housing whereby the assembly is secured in a weather tight configuration in its retracted position. The assembly also includes an extensible mechanism in the form of a pair of arms interconnected at their midportions and mechanically linking the emergency signaling enclosure and the housing with at least one free end of each of the pairs of arm assemblies being in sliding connection to its respective enclosure or housing whereby the enclosure can be raised to an elevated position entirely without the housing and at a substantial spaced position above the roof of the vehicle. Optional variations of the invention include folding skirt means extending between the enclosure and the housing whereby the extensible mechanism is enclosed. Preferably, the emergency signaling enclosure carries a plurality of emergency lights such as flashing beacons and the like each of which is mounted in a separate chamber of a multichambered enclosure.
