. An orientation sensitive light for mounting on a vehicle such as a motorcycle and the like, comprising:
a housing member, having means for attachment to a vehicle;
a light emitter coupled to the housing member, wherein when activated the light emitter shines light in the downward direction with respect to a normal operational orientation of the vehicle;
a switch compartment, stored inside of the housing member, having a longitudinal axis, wherein the switch compartment is conductive, has a cavity, an anterior and posterior ends, at least one first electrical contact extending within the cavity and secured to the posterior end of the switch compartment and communicating with the exterior of and insulated from the switch compartment;
a quantity of electrically conductive liquid stored within the cavity of the switch compartment such that upon deviation of orientation of the switch compartment from a horizontal plane, where the anterior end assumes an elevation that is higher than that of the posterior end, the conductive liquid moves within the cavity and electrically connects the switch compartment and the first electrical contact;
means for forming an electric circuit between an electric power source, the light emitter, the switch compartment, and the first electrical contact.
