0 Lamp Flasher Circuit using FET

It can be used as lighting indicator and flasher in vehicles. Unlike the BJT based flasher, this one has higher current capacity thus can power not only LED but also bulbs or lamp.

Circuit Schematic

Part List:
Bulb - 1W to 30W bulb  rated 12V
R -  see table below
C -  see table below
Q - IRF530, IRFZ44N, or similar N-channel Power MosFet

IRF530, IRFZ44N pins

Rate of the flash:
Both bulbs flashes at the same rate or duration T but not at the same time. The duration T is approximately 0.7RC.
