Dot,
the two questions you have just put in are in the category - Instant Messaging - a function of the Internet much used by young people. They will be better placed in the Vehicles - Cars section.
Your question about the light on your dashboard sounds serious to me - best to include the make & model of your car.
As for your car radio question - this one - it will help to include the make and model of car & or radio and the most important piece the radio serial number.
Good luck...
