After a hit on the parkingplace backlights went out??

[mylovelytoyo]

Hi
Yesterday evening at the parkingplace a unkown workingcar hit my Toyota Corolla year 2005. 1,4 hutchback.
The hit took my Corollas back on the right side just against the backglas and it went broken and the all backlights went off both sides , besides my breakelights, other functions are functioning, like radio, lights inside,warm seats and radio,cigglight and so on...Can I by the change backglas by my self or do I need to leave a car at the service for that??.I took also a quick look at the all lightbolls back inside the trunk where you can change lamps if those had been broken too...but those looked fine to me???Or can those be damaged anyway?
Today I tried to find a fusebox inside my Corolla but couldnt find it to check if the fuse had gone for back lights??
Now I know that there are two boxes one inside the engineroom and the other one under the wheel inside the cupe on the driwers side....How in the world can I open it?? or take it out and look inside of it??
Can there be some electrical wires on the back , right side of Toyota Corolla which could get off somehow because of hit yesterday?I dont know what to do...I already had ordered a new backlightglas to the right side but I am worried if there is something else wrong I cannot see or think by my self?
Ofcourse I need to leave my toyota to the service if I cannot find a problem???
I am thankful if you could please give me some piece of advise and som pics perhaps also if possible....Sincerely....
