Random dash lights coming on typically is a sign of the ignition switch starting to go. I created a fairly comprehensive thread on the ignition switch in the Tech Article (DIY) section that you should read through and run the tests if you can. Replacement of the ignition switch is also covered in that same section. You can find a link to the Tech Article (DIY) Index in my signature below.
