90 Ls400 Warning Lights Goes On And Off

[lexiluv]

My warning lights(battery, brakes, oil, and another but I'm not sure what it is, also check engine light doesn't work.

The lights comes on after about 15 to 20mins of driving, they go off once the car has been shut off for at least 30mins to an hour.

What could be the problem?

I replaced the battery but I'm still having the same issue.

I am putting the car in the shop in 2weeks. I will make sure I come back and post the findings just in case someone is having the same problem.
