:banghead:

Wiggle the connector on the dim one. Probably a bad/loose/corroded connection. If it gets brighter while you wiggle it than it could hurt to either clean or replace the connector. There are readily available just about anywhere and they are reasonably priced.

1)Make sure, that your your light sockets are cleaned.
2)Don't touch the glass bulb on a halogen light bulb, because the natural oils from your skin will cause it to burn premature.
3) Buy another bulb.
