So I lost my Moon Meteor 250 light mount recently and went to buy a replacement before going back to commuting this week. Couldn’t find anything online, please help!

(any suggestions as to where to get one?)

Moon-sport website; products; spares.
I don’t know which of the mounts will fit your light.
Choose yours then contact uk distributor.
Alternatively ring bike shops to see which stock Moon & go from there.

If for some reason you can’t find anything, I’ve had success gluing rubber patches (from an old squashy rubbery handle bar grip) to lights and using toe clip straps to fix them to things.

It would depend on your light shape…
