I got one from VW, but I have to say it's as dim as a 'Toc H' lamp.
Unfortunately the guy dealing with it is on holiday, and nobody else can sort it out for me apparently. So I'll have to wait until Tuesday to get it sorted.
£3.24 is £3.24 after all.

If you never have a route planned ...how can you ever be lost?
The 12V 3mm ones are not as widely available and you might as well fit a superbright 3mm white one if you are leaving the blue insert in. It takes about 40 seconds to replace the resistor (1p each) and you can use virtually any standard 5mm Blue LED for a 'fit and forget' mod. Best of luck with yours TextRitter, you are having a fair share of hassle for such a simple replacement.

Mine hasn't got an insert. Unfortunately electronics and I do not get on
It's no hassle, as I am getting it ready to sell/MOT I want it as spot on as I can get it.
Thank you for your support and input AngeloEvs.

Proper VW ones is a small 1.2w 12v bulb with a blue filter.
LED's are all well and good, but a bit bright for the application, after a while of driving on full beam they dun't 'arf get on your breasticles.
From what I have read, people are fitting superbright 1000+ mcd Blue LED's with the existing 100 ohm resistor which will be far too intense and will also fail very quickly. If you are going to convert then the correct LED is the standard 8mcd 'diffused Blue' with a 1.5K or 2.2K resistor in place of the 100 ohm and this will give the correct intensity for night driving.

Non of my oil/flasher/battery/ main beam warning lights have inserts just straight LEDs into the housing.
Should my main beam be different then, ie, white bulb with a blue insert, instead of the red LED one?

Yes, the main beam has a small cylindrical bulb and a blue insert. Blue LEDs were not available back in the 80's. Even the bulb was too bright hence the reason for a limiting resistor to keep the bulb brightness down.

What he said.
Some early ones had a yellow LED for mainbeam tell tale, at least the others, red and yellow are meant to be irritating, to tell you of a problem but main beam tell tale needs to be just that, a tell tale, have it too bright on a dark unlit roda and they really pi$$ you off, just like those head units with all the flashy "pooh" going on, really offputting when driving.
