| Jonno1968 Member Since: 24 Oct 2013 Location: Leicestershire Posts: 245      | Main reason for asking is there is a white wire and a black wire...is it very safe to assume the black is the earth? Thats all i need to know.....i was to open them up and have a look......but it does beg the question....how do you change a bulb when needed! | ||

| mk1collector Member Since: 17 Sep 2009 Location: West Yorkshire Posts: 6772      | I'm no electrics expert but if it was earthed through the casing wouldn't only one wire be coming out? You might be best waiting for more electrical minds to add there thoughts. | ||

| landy andy Member Since: 15 Feb 2009 Location: Ware, Herts Posts: 6059    | The white will be the live the black will be the earth. You could do a continuity test of the two wires to the body to confirm if unsure. Can't help with getting into the light, but posting a photo would be a good idea.

 yes I agree , only problem is if the bulb earth is not insulated from the body of the lamp really only way is to check with a multimeter , check for continuity between wires and body of lamp but they must come apart somehow for bulb change , if they are that hard to get apart or you have to damage them to get apart I wouldn't be fitting them | ||
