The electronic lantern control circuit adds high-efficiency dimming and flashing to an existing battery powered lantern or flashlight or to a custom design. For the car it makes a great lamp for changing a flat tire, back seat reading or emergency engine work.
The flasher mode is useful for warning other drivers of your troubles and it may be adjusted to have a very short flash duration for long-term use as when the car must be left on the shoulder over night. When camping it is great as a low-power night light for the tent or the portable 'potty'--you may select only as much light as you need!
The flasher mode is useful for finding a boat dock in the dark or even attracting fish. At home, the flasher is a great way to tell guests when they have found the right house or to "jazz up" battery powered holiday decorations. The circuit is intended for 6 or 12 volt lantern batteries but it should work well with supplies from 4.5 to 15 volts without any modifications to the circuit as shown above.
