96 camry front side marker lights

Hi,
 
I need to replace both front side marker lights. According to the owner's manual, after I remove the bolt near the side fender, I should be able to pull the assy straight out. When I tried to do this, I feel resistance like the light assy is connected to something that I can't see. Before I really yank hard on the assy, I want to know if it should be this difficult to remove and if there is any trick to removing the side light assy? Any tips would be appreciated.
 
Thanks!
