What is this tiny lamp (bulb) type called?

[nigelmercier]

My VDO Tachometer has a tiny illumination lamp (bulb) in it that looks like this:

The pins are spaced at about 3.5mm.

Anyone know what this type of fitting is called? I could easily modify the holder with a LED, but I wondered if they were already available.

I've discovered that the generic name is a "wedge" and that the larger version is a W5W or T10.

I know them as 'grain of wheat bulbs' but the ones I am familiar with always have wire tails.

It's smaller than the one Sailorman suggested. I'd think it's more likely to be one of these - https://www.easy-lightbulbs.com/lig...mps/miniature-bulbs/wedge-base-capless/wbc37/ The website offers different wattage ratings.

Try boat lamps. They do a pcb base substitute.
Tip:

Chamfer the end to make it easier to insert.

I used them on some tiny fixed stern lights.

Thanks for the replies.

It seems the base is a "T1.1/2", like this: http://uk.farnell.com/cml-innovative-technologies/286-20l-lf/lamp-wedge-t1-1-2-12v-1-2w/dp/1139315

Now to find an LED equivalent ...

Now to find an LED equivalent ...

Lots around, but they may well be brighter than your old bulb. See here for example - http://www.ebay.co.uk/itm/12V-30ma-W2x4-6d-Super-Bright-White-LED-Bulbs-LED286W-x1-/251273298689

I replaced a number of those in the instrument panel of a car with the LED equivalent. The panel ran much cooler, but the LED shape meant that the light was focussed as a spot not as a flood.

I had to take the LEDs and grind away the dome to a less convex shape to spread the light more evenly.

You can certainly buy them (1.2watts IIRC) in packs of 2 from Halfrauds.

I always keep a packets as there are loads of them in my old Volvo
