Use the pulse width of NE555 to module circuit. Use pulse width to module PWM which is a flashing emergency light composed by You are not allowed to view links. Register or Login. As long as the wiring is correct, it can turn normally without any debugging. The mediation of VR1 can alter the frequency of blinking. If you want to delay the flashing moment, you can improve the capacity of C1. What you need to pay attention to is the heat turnning of triode T1.

Wouldn't something like this have issues with heat? I'm no expert though, so it's entirely possible I'm reading this wrong.
