Patent ID: 8104914

Claim:
A light device comprising: a lens being at least partially light transmissive; at least one light emitting element which receives electrical power from at least one electrical power storage device disposed during use in said light device, said at least one light emitting element being arranged so as to generate light which passes outwardly of said light device through said lens; a solar power converting device arranged to convert solar power to electrical power for recharging said at least one electrical power storage device disposed during use in said light device; a control circuitry arranged to control supply of electrical power to said at least one light emitting element during use; a light activation sub-control circuitry to activate said control circuitry at low light levels; and a test device including: an insulator; a first conductor electrically connected to said electrical power storage device disposed during use in said light device; a second conductor separated from said first conductor and electrically connected to said control circuitry; and a test switch connected across said first and second conductors, wherein at least one of said first and second conductors is disposed on a first side of said insulator; and wherein said test device is disposed between said control circuitry and said at least one electrical power storage device, said test device being disposed in a first configuration wherein electrical power is able to pass through said test device between said electrical storage device and said control circuitry, and disposed in a second configuration wherein electrical power is not able to pass through said test device between said electrical storage device and said control circuitry.
