Had the drivers side headlight bulb blow this week. Took the bulb out, bulb is fine and not blown, put the bulb in the connector and it works fine again.

I figure it was just a loose connection but no, when I reinstall the light properly it doesn't work again. Then noticed that now the passenger side bulb will only go to daylight running and not fully on when you turn the switch on the stalk all the way. So now I only have the passenger side light. Full beams work fine.
Inspected both headlight fuses under the bonnet (both fine) and tried the headlight relay in another Lude - headlights work fine.
Any ideas before I start ripping apart the car looking for issues?
Cheers
