High efficiency lantern with flasher and dimmer by LM358
The electronic lantern control circuit (fig. 1) 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 overnight.
