I installed green led bulbs in the speedometer and rpm gauges some time ago as I find that they are less bright for night driving. I would like to do the same for the dash temp,fuel,oil pressure and voltmeter but I'm not sure of the bulb sizes? I just found out that there is a place called classiccarleds.co.uk that should have them. I checked their PDF of the various makes but oddly enough they do not have a listing for Triumph??? Anyone know the size of these bulbs? Would I be wrong in assuming they would be the same as an MGA of that era? Any thoughts?
