I had a problem with my front bulb light at my bicycle. So, I bought a new one (LED) for the front, but somehow, the back bulb does not work anymore. I have checked the wires for loose connection, so I want to rule that out. Also it (the back bulb) was working in the past, so I want to rule that out as well. I am thinking now about the following to things:
- I think, the front and the back lights are connected in a parallel connection. So, both the GND and the + from both the front and the back light should be directly connected. Is that true? I could only measure GND here.
- Parallel connection also implies, the mix up of dynamo and back light at the connection ports of the front light should not matter. Right?
- Could the difference of a bulb light at the back and a LED front light be an issue?
Thanks for your help here, guys.
