US Patent 7401508 Illuminated rain gauge

An illuminated rain gauge comprising an elongated, transparent collection vessel or tube having upper and lower ends with the lower end thereof being closed by a plug and which has a funnel-shaped collector at the upper end thereof. The plug has a battery compartment formed therein for receiving a DC battery power source. A pair of LEDs are operatively connected to the battery power source and are positioned on the plug so as to direct light upwardly therefrom to illuminate the rain gauge. The electronic circuitry of the gauge is positioned within the plug and is controlled by a remote IF control device which signals an IF receiver positioned on the plug. The LEDs direct light onto the collection vessel so that the rainfall amounts may be determined during periods of darkness.
