Just purchased a used 2000 Tiburon and noticed that the passenger side front and tail lights do not work when the headlights are turned on. I changed the bulbs and the tail light works when the brake is depressed, but not when the headlights are on. Any ideas?

 

I accually just had the same thing happen on the left side of my tib the other day.
There is a 2nd fuse box under the hood, behide the battery. Check the left and right parking light fuses.
I think they are labeled LP and RP, and should be 10 amp fuses
