Remove back light *rav4 2012

Have you tried going into the trunk and removing the panels covering the lights inside?
Hope this helps.

Open the trunk, and pull back the carpet behind the tail light assembly-- you should see 3 different sets of wires going into the back of the tail light assembly. Pick the one you need to replace, and give it about a quarter turn counter-clockwise, and the bulb, harness, and wire can be pulled out of the tail light. Replace the burned out bulb in the socket, and reinstall the bulb just as you removed it.
If you have difficulty getting to the wiring harnesses to dislodge them from the tail light assembly, you can remove the tail light entirely by unscrewing the black plastic wingnuts that hold the tail light assembly in place. It may take a little bit of effort to get them started, but will allow you to see what you are doing a bit better.

You may have a fried fuse. Look in your owners manual to find out which fuse it is in the fuse box diagram. If that is the problem make sure to use the same amperage fuse to replace the burned one with. I fried fuse is usually a sign that you have a short somewhere. But they can also fry for other reasons such as excess moisture somewhere. Sometimes they just burn from age and fatigue. It may solve it to just replace the fuse, but if there really is a short, the new fuse will fry too.

Open hatch, remove the 2 screws on the side of the broken light, pull firmly and replace.

to replace the GM tail light bulb, you will drop down the tail gate and you will notice 2 screws on the tail light assembly, you will remove those 2 screws with the proper screw driver, once you do that the whole tail light assembly will come off, then you will see onother 2 screws holding the light panel to the tail light assembly, or brackets holding the light panel to the tail light assembly remove either or and you will have access to the three bulbs on that light panel, replace the burnt one and follow the same intrunctions to put back.

inside the trunk behind the tail light,pull the carpet down and remove the screws,nuts,bolts or the finger nuts and the light will pull right out

Yes, you have to remove the plastic panel. It is mostly held by spring clips. You can see how to remove it at the link below.

You did right so far. Once you have lowered the tailgate and removed the upper and lower 10mm bolts the tail light assembly should be loose and moving a little bit. There are only 2 push-in plastic posts holding it at this point now. Then you have to pull back the assembly firmly, hit on the external side of the assembly with the palm of your hand and it will pop out. DO NOT try to pry with a screwdriver or any other tools.

Disconnect wires connections, replace burned or broken bulbs, make test. If it doesn't work check if the wiring has been affected by the accident.

Hope it will help

Most of these type lights do not have a plug. I am assuming that you want to replace a burnt out lamp.

Here's what you do. Remove the assembtail lamp assembly. It is usually held on with 2 or 3 phillips head screws. If the problem is a burnt out lamp, the lamp assembly will unscrew from the unit by turning it counterclockwise about a quarter turn. Take the bad bulb to an auto parts store and get a replacement. The bulb will only fit one way into its socket. Then take the socket with the new bulb and insert it back in the housing. Again it will only fit one way. remount the tail light assembly.

If the actual plastic tail light assembly is broken or cracked remove the lamp assembly as described above, take the broken tail light to a dealer and ghet a new one. They are expensive. I just replaced one for my 95 F-150 pickup and it was $40.
