Ditto, fitted a super bright LED from Horizon LEDLike the man said the whole light just pulls out it is sort of spring loaded so may need to push slightly to one side or other and pull it out at same time. I changed mine for L.E.D brighter light less power.
Aha, thanks, that's what I want to do so thanks Niall and Gremlin - I'll get on the Horizon website.
