I just incurred a strange problem in my 92LS. When the lights are on the headlights do not work. The rear lights work and the side lights work. When in drive and I press the gas 3 additional lights come on the oil pressure, BRAKE, and radiator. I also observed when I press the Hi Beams only the left side light works. I am not sure if it is a bad headlight or bulb, a short, a ripped wire, a fuse or a relay. I do not know where to look first. Can anyone shed some light on this issue.
