Hello, I'm currently doing an electrical refit on a 29' Bristol. I have an anchor/steaming light for the top of the mast. I'm connecting them to two separate single pole single throw breakers. My problem is that I need the steaming light (fwd light) to be able to come on indipendantly from the anchor light (both light) and vice versa. I know I can just put a diode in-between the breakers to solve this problem. But I'm not sure what sort of diode I need. It's a 12v system, each breaker is 5 amps. The lights themselves don't even draw one amp combined. Any help would be greatly appreciated. Thanks!
