Dim indicator

Hi,
What would be usual reasons for a dim indicator light?
Earth maybe?

 

Bad earth, or give the bulb/holder connections a light polish?

 

Check the spade connectors either side of the engine hatch

 

A very old light bulb whose filament has evaporated all over the glass making it black..

Or bad connections.

 

Wow.... The power of good clesn earth connections..

All fixed.

Don't you just love a simple satisfying fix.
Thanks for suggestions.
