[Mgs] Broken LED Lamp in Oil Gauge

Hello Robert,

I changed my MGB GT V8 tacho and speedo to SpeedHut ones because my car 
is not 'original' as I built if from parts - souped up Rover engine from 
UK !!!   But the new instruments are LED and I discovered were not too 
happy with the rheostat dimmer.   So I installed an LED dimmer for the 
new SpeedHut gauges and kept the 'old' rheostat one for the remaining 
gauges.  So I have two knobs for dimming which is actually very 
convenient - small gauges low and tacho and speedo brighter.   
Incidentally, the SpeedHut ones are awesome - the speedo is run off GPS 
so no mechanical connection to car and deadly accurate plus all sorts of 
options.

Cheers
Barrie

We think it was caused by the cheap sheet metal thread in the bulb holder.  The LED bulb was seated at a slight angle when screwed into the holder casing the bulb to break in half.  Kind of fragile at $5 a pop.  A lot of work and new four letter expletives I didn't even know there were.  Would have been impossible to remove with the gauge in situ.  Came out easily with a pair of needle nose pliers..  Just something to consider if you're thinking of converting to an LED dash.
