How do I get to the interior light?

[2001REDCELICAGTS]

I unscrewed the one screw that was holding the the light fixture in. Then I try to pull the the fixture out it would not budge. I was afraid to pull too hard. What is the right way to do this?

Dont be afraid to pull hard. You are doping the right thing. When I changed mine I thought I was going to break it but you just have to be firm cuz it is really tight.
