Abstract: A warning light assembly includes a source of electrical power, an LED light source, electrical circuitry operably coupling the source of electrical power to the light source and a lens assembly. The lens assembly encloses the LED light source such that light from the source is directed outwardly from the lens assembly. The lens assembly is triangular in shape. In certain embodiments, the electrical power source includes a rechargeable battery and the assembly further comprises a solar panel operably connected to the rechargeable battery. A triangular lens assembly may be connected at a vertex to a housing which holds the electrical power source. The solar panel may be mounted on a peripheral surface of the lens assembly opposite the vertex.

Abstract: A rechargeable solar lantern with an improved power control circuit. The power control circuit includes a first switch, actuated by the connection of the solar panel to the battery, to prevent power from being supplied to the light bulb when the battery is charging. The power control circuit also includes a second switch to prevent power from being supplied to the light bulb when the voltage falls below a predetermined unacceptable level. Preferably, the second switch remains tripped until reset by the actuation of the first switch, indicating that the battery is being recharged.

Abstract: A surgical needle with a stylet selectively received within the lumen of a cannula is shown where establishing and maintaining a desired angular orientation between the stylet and cannula is achieved. The orientation may be determined in one of several ways. Preferably, a projection is mounted to the cannula hub which is selectively received in a recess of the stylet cap when the stylet and cannula are in the desired orientation. Alternatively, a pair of flexible arms may be mounted to the stylet cap wherein detents on the distal ends of the flexible arms are selectively received within complementary depressions on the cannula hub when the stylet and cannula are in the desired orientation. Also, a longitudinal rib on the stylet cap and a projection on the cannula hub can be visually inspected or can be felt by the user to determine the orientation. Finally, a projection from the cannula hub may be selectively received within a slot on the stylet cap to ensure proper alignment of the stylet and cannula.
