I'm guessing this is a halogen light.
Probably there's oxidation in the socket contacts to the lamp.
You can pull out the bulb, clean (scrape) the pins, and
use a welding tip cleaner wire (kinda like low-bite circular
file wires, used for acetylene torch maintenance) to clean
the socket.

Don't get fingerprints on the bulb, or use any cleaners that might
leave a residue.
