Abstract
A tilt switch activated light apparatus suitable for use in connection with an egress of a vehicle, the apparatus including a magnet disposed within a cavity of a housing, where the cavity is shaped so that in the event of excessive roll or pitch of the vehicle, the magnet moves to a location adjacent a switch connecting a power source to a light source, causing the switch to close and so activating the light source. An external body, either ferromagnetic or magnetic, and external to the housing and removable therefrom, may be used to hold the magnet inside the cavity in a neutral position, away from the switch, during shipping.
