Fuel gauge bulb replacement?

[mud352]

So thanks to the helpful posts earlier I’ve managed to change my Speedo and tacho bulbs and they look great. I’d like to have a matching bulb in the fuel gauge but, I can’t see how to do it? Can anyone assist please? Thanks

The RID is a sealed unit.

Thank you Sir! In that case I’ll leave well alone

Thanks
