I don't see any point in having a lamp lit 100% of the time?
And... we have a working odometer 
I then checked it against a gps app on my phone (The app is called DigiHUD, its quite good, you can make it project onto the windscreen).
The odometer is accurate to the GPS.
The speedo itself appears to read 4/5mph fast all the way up - perhaps the car isn't _quite_ as slow as I first thought. |
Wow, a fuel gauge that actually does something! A novelty on a 7/9xx i reckon!
That greeny/yellow telltale is actually your sidelights on warning - designed to let you know the sidelights are on if you've been driving on sidelights and switched the ignition off. The sidelights remain on if the headlamp switch is in the sidelights position.
You removed the speedo needle to do the job, didn't you? If you got it back a couple of degrees out from where it should be, it will read 4-5mph fast all the way. Usually speedos read 5-10% fast, my 760 read ~14% fast until i fitted 195/65/15s on it, then only about 7-8% fast - 205/70/15s would have pretty much corrected it completely but not worth the extra cost.
Sounds like you've made some excellent progress there!
