Series 3 Bulb holder to suit 3-in-1 guage

Hi,

I'm currently fixing the wiring and lighting on our 1977 S3 Diesel instrument cluster. There is no lighting at all on the 3-in-1 guage (fuel/water/charge) as someone in the past has seemingly removed the bulb and holder - leaving just the hole in the back of the guage.

The 1st spade connector on the panel lights toggle goes to the speedo light bulb via a single red-with-white-tracer wire, which works fine. The same someone in the past seems to have reused the 2nd spade connector coming from the panel lights toggle switch to go elsewhere (exactly where is to be determined), but I'm assuming that this should actually be going to the back of the 3-in-1 via a similar red-with-white-tracer.

My question is: What type of bulb holder do I need for the back of the 3-in-1? It doesn't look to be the same style as the one in the speedo - for a start the hole is not as wide and is more of a shaft rather than a simple hole in the casing.

Thanks

Can’t remember if this is fitting is the one that slides in a tube or grips in the hole with a star shaped spring.

This is a warning light holder


This is the other

Hi,
Thanks for the prompt reply.

Yes, its the first type (red background) type that I need, takes an E10 bulb. The holder that was there at some point in the past has vanished - its not down the back of the dash loose either... and I can't find any metal ones on eBay. Plenty of plastic examples with two wires that I guess I could modify if it came to it but I'd prefer the original single wire metal style.

A bit 'pricey' for what it is.....

Yes, I'd seen that one...but like you say, it is a bit steep. Thanks though.

Those bulb holders are earthed through the casing and if your dash is anything like mine it's rusted to buggery. That means the lighting is intermittent to say the least. Get a 2 wire one at least that way you can give it a good earth.

I half remember the Morris Minor having the same socket but you’d need to research its size.

One of these might fit:

I used one of these to illuminate a Smiths oil pressure gauge (and the extra red/white wire you have might have been for an extra gauge at some point).
+1 on checking the gauge earth - and on the speedo as well.

If you want the illumination light and you have a plain hole then its one (or is it 2?) of these:

There's plenty to choose from:

Time was when you could go to any scrappy and pull and handfull off.

Sure the second one in Bobsticles post is alternator lamp not illumination.
