dash lights!!!

I was driving to work when some of my dash light suddenly came on, the radiator light, battery light and emergency brake light. The car still drives fine but those lights aren't going off. What could be the problem?? I tried unpluging the negative terminal on the battery then reconnecting it again but that didn't solve anthing. Any help would be appreciated, thanks.

Those lights will trigger if your battery loses power. Make sure both of your terminals are on tight.
