To use light emitting diode or LED in your motorcycle, ordinary thermal flasher wont work due to the high resistance of led, and that it needs to have a load resistor or dummy load in order to flash leds, which means a power waster.  Many light enthusiast of course didnt understand this that after replacing their signal bulbs to all leds, it didnt blink or blink too fast. Solution, A Universal electronic led flasher.

Figure 1. is a solid state two wire led flasher that will flash even a single led without the use of load resistor. It is so versatile and will prove useful in any number of circumstances. The circuits scales from micro amps to amps and from microseconds to minutes.

The on time may be increased by selecting other values of the 10k ohm resistor of the 2n4401 npn transistor as long as the resulting base current is sufficient to saturate that resistor.
