I have an 1993 Infinity G20 a week ago I got home ,turn off my car but my left headlight stayed on even when the light switch was off and the key was out of the ignition.so I disconnect the bulb wirings.after couple of days it was fixed till last night it happened again but this time the light was off when I went to sleep ,but in the morning I found it on plus the burning smell inside my car, Does anybody know what is wrong with my car???
Thank you

iF ONE HEAD LIGHT COMES ON AND THE OTHER ONE DOES NOT,IT MAKES ME THINK YOU JUST MADE THIS UP.tHE REASON IS THEY ARE HOOKED IN PARALELL AND BOTH LIGHTS WOULD BE ON IF ONE HAD POWER.,UNLESS ONE IS BURNED OUT.sOUNDS LIKE A BAD SWITCH WITH ONE LIGHT BURNED OUT.

It could be simply a broken headlight switch, or headlight relay is burned...headlights are direct wired to the battery, so fix it now, it can cause a fire...

I don't think you have one, but a delay relay could be faulty...did your headlights/interior lights stay on for ten seconds before?
