Replacing Blinker in tail lights (2nd gen)

I was trying to take off my tail lights and replace the orange blinker bulb with a red bulb on my 07 outlander, but I couldn't get light housing off. After I unscrewed the screw holding the housing in place it became loose but wouldn't come off. It seems like there is some kind of hidden clip or another screw I can't see. Do I need to go in on the side panel in the rear cargo area to get to the blinker bulb? Does anyone know how to take the housing out so I can replace the blinker bulb?
 
Thanks,
Ryan

Look in your manual there's a diagram that show you how to remove it.
