    Just bought a 12v led strip light with built in switch.to fit under bed.question. I have spare 12 supply but can only find one red wire which is definitly 12v.the light has two wires coming from it + &-.do I need a transformer?.If I wire red wire to + does other wire from light go to earth.I know to some this may be obvious. do I fit an inline fuse between light and wire from motorhome.Any help appreciated.:thumb: led light.jpg

    Hi.

    A transformer NO, they only work on an AC circuit not DC.

    You need the + 12volts which it sounds as if you have found also a earth (-) connection.

    It would not do any harm to put a fuse in the circuit but I would think the supply you have found would already be fused, it might just be a case of finding how strong a fuse is on the feed.

    Maybe not. If it's feeding something needed 20A ( or more than 5A ) you have to leave it and put an inline one between the red and the light.
