Land Rover Repair: 2003 Land Rover Discovery, land rover discovery, reds lights

Question
What does a "Red Light" that comes on the left-hand side of the dash mean?

Answer
There are too many reds lights on the dashboard of a modern car to answer such a general question.  However, you can get the answer in yoru owner's manual where there is an illustration of the dash with explanations for every light.  If you don't have a manual you can go to www.landrovertechinfo.com and download a copy.  You may have to pay a small fee for a day's access but it's going to be cheaper to pay for the download the manual that it would be to buy one through the dealer parts department and you get full access to all service info on the factory site too.
