It's unlikely the lights are faulty, they are just bulbs and cable.
And almost everything is failing.
You have tail lights, just not in the tailgate so I'd figure cabling
 
Definitely not faulty lights or just coding. Your old lights don't work.... the rear wiper doesn't work... You need to be looking at all the wiring related to the rear hatch.

But when i open my car the lights come on but only the left side but stays on for a second and den switches off
