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!

Surely if it's a standard bulb, it won't matter which is earth and which is live.

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.

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.

Like I said, if it's just a bulb then it won't matter which way around. Try it on a battery.

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 |
