I own a BMW X5 3.0 The rear lamp assy and tail lamp assy on tailgate were replaced due to rear end accident, repairs were made at the bodyshop. All the lights work but the computer keeps saying to check rear/brake light.
Remove all blubs from rear lamp assy. check for any signs of corrosion[no matter how small] clean the contact surfaces with fine wet and dry or for larger areas clean and refill with solder,replace bulbs and test.

Before servicing the vehicle, refer to the Precautions Section.
The rear lamp unit may contain up to four bulbs, depending upon the market for which the vehicle was manufactured. The service procedures for each bulb are the same, only the bulb sizes and types may differ.
Disconnect and isolate the battery negative cable.
Remove the rear lamp unit from the end of the quarter panel, as follows:
Open the tailgate to access and remove the two screws that secure the rear lamp unit to the two plastic nuts in the side jamb of the tailgate opening.
Pull the outboard side of the rear lamp unit rearward far enough to unsnap the two ball studs on the outboard side of the lamp housing from the two plastic grommets in the quarter panel.
Disconnect the wire harness connector from the lamp socket plate connector.
Remove the lamp from the quarter panel.
Remove the two plastic grommets from the quarter panel and discard.
Firmly grasp the socket on the socket plate on the back of the rear lamp unit housing for the bulb that is being removed and rotate it counterclockwise about 30 degrees to unlock it.
If this is an original equipment replacement part should work just like its predeceser before the accident. Just check that everything is wel connected and in place by removing the panels and take a look inside.
Open the rear tailgate and remove the two screws that hold the tail lamp assembly in place.Now there are two alignment pins that hold the lamp in place, you must use a
screwdriver or other flat device and lightly pry the lamp your working
on. If you are removing the rear left (driver side) then pry back outward to the left. Alternately, if you are removing the right rear tail light, pry outward to the right. Do not try and pull directly back. The pins will prevent the light from coming out. You have to pull left or right, depending on the light your removing. Good luck.
If this is a Blazer and not a newer design Trailblazer...
Open up the tailgate / ;iftgate and there are screws on the inside surface of the tail lamp assemble. Remove the screws and then pop out the tail lamp to gain access to the connector for your signal bulb. Twist the connector to remove from lamp assembly. remove and replace bulb.
to remove the fog lamp assy u must go under the truck, it is held in from the rear, there will be a couple of studs and nuts you remove, I am a little confused hear, you have fog lights in the rear of the truck? is this a typo?
Humm ...Didn't die before the accident? now dies? BMW has good mechanics,but could not find any problem???. I gota think that it is related to the rear ending,but how? I would look for loose connections, Battery Ground that might have been removed before welding.Battery terminals, Any primary connections that may not be making 100% contact . It's worth a try.Good Luck
Do you need to change a bulb or are you changing to custom lamps. If it is bulb replacement open trunk/boot (depending where you live ) the access for the tail lamps is at the rear corners of the trunk, If you are changing lamp lenses or assembly remove the screws( same location ) at lamp corners
