ODD lights

I have a 1990 Buick Century (my old one done this and never found an answer for) I have NO traction control or antilock brakes on this car, but these two lights keep popping on for NO reason, like when I'm driving down flat straight highway the low trac light turns on, and EVERY time I TOUCH the brakes the antilock light turns on, like I said NEITHER of these are on my car, and at times the theft light blinks when the key is off and I have no theft detterent system on it, any explanation would be appreciated, it done this on the old BLUick and now on the "silver rocket" I'm confused and frustrated.

GREAT now all three of these lights are stuck on and it's starting to piss me the fuck off, I've taken it to three automotive electricians and two mechanics and they have come up with nothing. I think I've got three lights about to be missing from the dash.

Black electrical tape would be easier and won't damage your dash:D
