This is a bike light I have made because of the fact that the commercially made versions are way too expensive for my needs and I thought it would be fun to make! I’m using a 20W 12 volt bulb and two R/C car batteries rated at 2000ma/h and are 7.2 volts each. I linked them in parallel to double the voltage so effectively I’m ‘overvolting’ the bulb which does in turn reduce the life span of it!
