Hi guys, I like your site very much, but I need your help. I'm working on a diagram of electrical system for trailer hitch on my car and don't know how to draw a bulb or fuse. Can you tell me how to do this? Thanks. John

For a bulb just use a resistor and draw a box round it (from lower down the left hand the panel) to remind you it's a bulb.

Lower still down the left hand panel, under the Unsorted Elements heading, there's a fuse symbol.

You could use the fuse with a box round it to represent a bulb but you must set it to have a non-zero resistance if for any reason you wanted to run a simulation of the circuit.
