Ok I'm wiring up my night lights on the boat. This is a DIY job, and I figured it would be best to rig up my circuit so that everything is in series like this: POS Battery >>>>>All Around Light>>>>>>Switch>>>>>>>Navigation Light>>>> NEG Battery Now then here is the part that has me stumped. If I leave out the navigation light, the all around light works. If I connect the navigation light to the circuit, it works, but the all around light doesn't. WTF is going on with it? Why don't both lights work, especially considering the navigation light is wired in first? I guess I might just have to add on another switch and make it all paralel.
