Dome Light

99 sonata gls. The left side is working and the right side isnt lighting up so the bulb is burnt out, went to automotive store but they had no bulbs. Anyone have any tips on opening the dome light to change the bulb.

So while picking up my brake fluid I also tried to get a domelight bulb. Guy at napa showed me a bulb that had metal on both sides and it was a tube but my bulb is a small bulb. Went to hyundai dealer but they close at 5:30. Anyone have this problem before?
