They're fitted to all SE spec cars, I would imagine?

It tells you if you've had a bulb fail, if you've left a door ajar which one it is, if you're running low on washer fluid and.. er, in a V8, that's pretty much it.

The computer functions in the V8, off the top of my head are average speed, digital speed readout, a second trip meter and a speed alarm which you can set at the speed of your choice. OK I guess, but nothing like as useful as it could be if it was rigged up to show things like fuel remaining. Having said that, I once deliberately ran a Saab 900 Turbo down to empty with a can in the boot, just to see where it thought empty actually was. At the time, it was telling me I had a remaining range of minus 43 miles!
