Light Signal circuit

A simple but useful and stable circuit. In this state, it easily operates a 50W lamp without needing cooling. Of course, it got a little hot in my 100W experiments by connecting another one in parallel, but we can solve this problem by extending the length of the PCB a little and expanding the cooling area for the MOSFET, or a small cooler can be added by choosing a MOSFET with a TO220 sheath.

Bicycles, motorcycles and your desire to signal can come in handy almost anywhere. Think of a bulb connected to the battery, cut the positive line and connect this circuit in series, that’s all, just make sure you don’t connect it in reverse.
