Abstract: The inventive signal light structure includes a fore-and-aft track mounted atop the dash of a vehicle and extending back from the windshield to a rear part of the dash, plus a lamp housing mounted on the track for fore-and-aft sliding between front and rear positions. A hinge on a transverse axis is included in the track follower so that the housing may be tilted rearwardly and downwardly when it attains its rear position, thus disposing the housing in an out-of-the-way mode.
