Flashing Light with Dimmer
Most cheap emergency flashing lights at fixed locations employ glass-based bulbs to generate light. The typical filament bulb is fragile, has a short lifetime and requires a (relatively) high voltage. To overcome these disadvantages, the author designed the above circuit, using a solid-state light source, a dimmer function and readily available ICs, all aiming at maximum compactness.
