Tach & Speed-O bulb access

[Tony C]

Just received some of those nice LED instrument light bulbs, as recommended on BC - thanks for the info.

 

I've installed the ones in the other instruments, but can't see a similar bulb access on the big dials. Do I have to remove them from the dash and take the back off?

 

The LED's are white and the effect is great. They make the Mocal gauges look crisp and give the light in the Caterham gauges a very slight blue tinge - I checked to see if they'd included one of the wrong colour, but it must be the instrument 😬 The light was a different colour with the ordinary bulbs too.

 

Just a tip - I couldn't get one LED bulbs to work and it turned out that I had reversed the bulb holder wires when carrying out previous work Blew the fuse fiddling about, couldn't immediately figure-out which fuse was for the instrument lights (It's No. 6), didn't have a spare 7.5 amp, fitted a 5 amp instead - yada, yada - the usual comedy of errors 😬

If you have fairly new gauges then the bulbs are behind a black grommet on the back face. They are also probably PCB mounted of the 90-deg twist type, not the same as the older bulb type.

Thanks Phil 😬

 

I noticed the grommet - I'll have a look under it tonight.
