My under bonnet ligh doesnt work, i just fitted a new light and wired it into the plug beside the washerjet, but still no light, the microswitch works fine as the interior lights come on when the bonnet is lifted.

Thanks

Do you have your parking lights or headlights on when checking the underhood light? It only works when the other lights are on.

Hmm, the interior lights come on when the hood is lifted?
That has me a little worried.

But yeah, I thought mine was broken until I realized the parking lights/headlights need to be on for it to work.

Besides having the parking/running lights on for the light to work, check out the socket that the bulb screws into. I think almost all of them were mercury switches - you can tell if the socket is quite a bit longer than a standard socket would be. Mercury switches don't usually fail but yours may have.
