This is a good and simple circuit to flash one or more LED lights. The circuit uses a NE 555 small IC. This IC is very common and easy to obtain from any electronic components shop. As you can see in the circuit diagram we have used 10uF capacitor to control the flash speed of the LEDs. If you want to increase the speed simply put a higher value of a capacitor in place of 10uF.
Also you can increase the number of LED lights in parallel way. The maximum we recommend is 18 lights. Use PCB board to build this and supply six volts. Do not supply more than six as it can damage the your components as well as LED bulbs.
