Long story. I have 2 s light sets of cold cathodes for inside my car boot. 2x Red and 2xwhite. This is for when ive got my telescope out on a night time near the car. The plan is to have a red and white on either side of the boot and have it switchable. I tried to lengthen the cables for one side, and got nowhere, looks like the current drain is too much at the 1.5m distance i need. Even at a 0.5m extension it became very dim. Does anyone know what voltage and current the inverters run at on the AC end? My multimeter doesnt seem to like measuring AC. I plan on sticking a switch on the cathode end, but need to know what rating of switch i need.

Nope, tried thin and thick cable, they dont like it at all. I think it was 18AWG i used, not sure. The same stuff used for car electrics. The plan is to attatch the dual inverter and switch on/off the cathodes individually. Not sure what rating of switch i need though. Dont want it to set fire to my scope!
Yes, but im after a red light on either side of the boot, and a white light on either side of the boot switchable between red and white. With that way i will need to buy another 2 inverters. Which im trying to avoid. Being more expensive.
I thought i would be fine on a 2 metre run too! Hmm. Ding! Think ill try mains cable
. Even so, the existing wire on the cathodes is only thin.

One inverter will supply 2 cathodes, which is fine, but I want one white and red at either side of the boot. Hence the problem. Think ill get some mains switches. They tend to be pretty well isolated.
