Has anyone installed LED reverse lights on their CLS?
This should take you around 30 minutes. Novice level difficulty.
Remove the two plastic trim fasteners.

The picture does not do justice to the difference.
Less than 10 tools needed. (see picture)
- Remove trunk carpet.
- Remove both side cargo net's (unsnap pull out)
- Remove (2) cargo tiedown on both sides (just the closest to the rear of the car) Remove with Torx T-40
- Remove black molded plastic trunk pane. Loosen (no need to remove) the two 10 mm plastic nuts, remove the twp plastic trim fasteners, pry straight up to pop the 4 fasteners that hold the trim piece from underneath.
- Carefully peel back carpeted side panels from rubber butyl and use a bungee cord to keep trim piece pulled back.
- Unplug trunk courtesy lights using a small flat bladed screwdriver.
- Remove the four 8 mm nuts on each side to slide rear light assembly housing out. The forwardmost nut on the driver's side you will need a socket extension to reach, I suggest using museum putty or similar to keep the nut seated in the 8 mm socket. Or good luck finding it when it drops out.
- Unclip rear light electrical connector using a small flat bladed screwdriver.
- Remove 921 halogen bulb and replace with LED bulb.
- Reverse steps to finish up.

Cree led bulbs with chrome looking housings will look a load better than bulbs made of lego behind the clear lenses .
Thank you.

Not the best for "vertically" mounted bulbs.
