I needed a 12volt car accessory plug to use with an additional led light. Halfords didn't have any, tried Maplins - yes, £2.99. Excellent and surprisingly cheap. Alas, total rubbish. No way of connecting the wires... it had to be a botched soldering job....and a big risk of short circuiting. Even worse - most times it refuses to work. Is there anywhere I can get a DECENT 12 volt accessory plug?
