I did this on my previous '2 with some LED towers from ultraled's, IIRC they were BA9 233 type bulbs which fitted fine and were bright enough, but they don't seem to do them anymore, and none of the ones they do look like they would be very good as interior lights.So I bought a couple of bulbs off ebay, but on delivery they are much bigger than the bulb holder
- they are in fact BA9s bulbs, but Ultraleds lists BA9 and BA9s under the same category, and quite a few ebay listings have both BA9 and BA9s in thetitle so Ihad assumed they were the same - clearly not?Can anyone shed any light on what all these letters and numbers mean? Is BA9/BA9s related to the pin positions rather than the size? And if so what size do I need? I know it's 9mm but is there a designation for this
(the bulbs I bought are T4W whatever that means?).I cant seem to find a guide anywhere on what all these terms mean.
