MG MGB Technical - Replacing dash bulbs

I didn’t find how to replace dash bulbs in the archives. I have a 1974 mgb roadster and am wanting to know how to replace the dash bulbs. Thanks George

Mostly the holder just pulls out of the back of the instruments and the bulb unscrews from the holder. It's a matter of reaching up behind the dash and feeling around, Google the instruments first to see pictures of the backs if you don't know what you are feeling for. Assuming a USA spec you may have an under-dash panel to remove first, I believe.

I did this in the fall. Paul is correct. The bulb holder pull out of the back of the gauges and then the bulb unscrews. I was unable to get at the bulb for the speedo. Just too much stuff in the way. You may need to find a volunteer with skinny hands for that one!

I replaced mine with LEDs. Big difference in brightness. Good luck!

Indeed, LEDs make a huge difference to the gauges, as in the attached. These are bright white LEDs which is why it's a bit blue in the picture, from the paint inside the cans. I didn't intend it to be like that, just hadn't realised the difference between bright white LED and 'yellowish' incandescent. If you don't like the blue then warm white gives a closer colour to the original.

Google 'E10 5 5050 SMD LED' for a direct replacement for the screw in type. The only thing you have to watch is that they are longer than the original incandescents, I had to space it back a bit in one of my speedos, and I've heard of someone having to do the same with a dual gauge.
