Claim:
A lighting apparatus useable with a bicycle or other manually operated vehicle comprising: a first housing within which a central processing unit and at least one power source are receivable, a second housing, including a light emitting element, that is adjustable to multiple angular positions relative to the first housing to provide illumination at different emission angles, and a pivot mechanism, by which the first and second housings are attachable to and detachable from each other, that allows relative pivotal movement between the first and second housings and permits electrical communication between the light emitting element and the power source when the first and second housings are attached to each other, the pivot mechanism including a main part with a plurality of contacts permitting said electrical communication, an actuator axially reciprocable relative to the main part to alternately permit detachment of the housings from each other and locking of the housings together with the second housing in one of said angular positions, and a spring biasing the actuator away from the main part.
