So I'm check-listing my car getting it ready for its next MoT, and I got to the dash lights. I saw that one was not working, so I pulled it all out and the bulb is missing, that's not a problem in itself as I have a couple spare, but I got thinking, and I don't actually know what this light is for. My first thought was ABS warning light but then I didn't think that I had ABS.. So my question is, does anyone know what it is for?

The photo isn't of my car it's one I found on google but the light is exactly the same as the one I mean. Many thanks guys. Jay
