I'm trying to change the parking light on my 2009 Toyota Yaris Hatchback, and running into some trouble getting the panel off. Hoping somebody can help me out.
The following picture shows the enclosure (working driver side (left)) I've removed the 2 nuts, however, the tail light cover still won't come off. It appears held on by something in the lower left (facing from outside).
I noticed what appears to be a plastic "bolt" ? shown in the next picture ... not sure if that's what's holding it - but if it is, I have no idea how to remove it ?
Any help would be appreciated.
 Forgot to mention, I'm trying to change the light bulb for parking light. The top light of the three lights. [/edit]
[edit3] A better picture, showing the top parking light I need to change. (it's actually visible in my first picture as well, the one showing the 2 nuts I removed. I'ts just to the right of the top most nut).
