Hi there everybody
Probably a dead simple question, but anyhow, here it is.
What I would like to do is to add a circuit to my motorbike headlight, so that if the power is cut, say from the fuse burning out, the new circuit will cut in and keep the light lit. Had a bit of a fright last night, you see :shock:
I know how to hook up a relay to do this, but I don't know how to get the relay to kick in when the power from the other circuit drops out. My initial thoughts are that I need a transistor that is set up to block power going to the relay switch, but I am not sure if that will work, nor am I sure if that is the best option. Ideas would be welcome!
Thanks.
