Group, I also found in another car a 12 volt, 5 watt, JAHN UK bulb. It's shorter in length but same 10.3 supposed to be width. It is also closer to 11mm in width. This is equal to in Sylvania/Osram. Number's 2820,2821,2825,2826. The 2825 and 2826 only have a 300 hour life while the 2820 and 2821 have 1000 hrs life. 2821 has the least amount of current draw 0.25amps at 14 volt rated test.Why they did that I don't know, but it's astric that way.
