I have a little problem that started today. My brake light, oil light and my battery light stay on after they key is out. Also my air bag light stays on also. It just started today I have not done anything different in the pass year. Light just stay on. I am afraid that it will drain my battery so I just disconnect the battery every where I go. Need help if you guys might know anything.I checked the fuses and it seems fine. I dont know if something is touching or what as in wires touching. Let me know any suggestions you guys might have.

 

It might be the ignition switch itself. Remove it and test it, or clean it up and see if the issue goes away.

 

The same thing happens on my 98 racecar when I leave it uncovered in the rain. I have no windshield and non-stock ignition switch.
