H7 Nearside Dipped Beam replacement -bulb warning

[Beedge144]

Hi forumites, driving back from Scotland last night my nearside dipped beam failed, and had the usual warning light indication on the message board.
I opened up and replaced the bulb today, and it's still U/S
I sprayed the connector with a contact cleaner, to no avail.

I did change the Offside equivalent about a fortnight ago, and had no problems.

Is there any potential for a failure in the wiring loom or anything otherwise ?
I'm not an electrical wizard, but can at least have a go at most things
Going to need this fixing over the weekend as I have to head back north next week
