HELP!

One of my 2015 Challenger rear lights is out. Can not find a driver that fits the screw. Some rust in socket so my old eyes can't be sure how many sides to drive. Tried 15 and 20 Torx - to small and to big. Swear it looks like eight lobe/node.

Later - OK it was eight - first time I have ever seen "double square" drive screw. Std square drive worked. BTW if you need to remove tail light assembly - remove screw and carefully pull entire assembly twords rear. There are two rectangular plastic pins on the outboard edge that point to the front.

Congrats...yep, seems it's a thing:

Leave it to TMC to use a fastener that is rare. Our Thor era Damon is FULL of Robertson drive screws...and after working on it for these years, I have come to enjoy how easy it is to use these screws, 'cuz they hold on to the driver - hands free for retraction and install

Safe travels

Whent thru the same thing with my 2007 Discovery! Needed to pull the rear tail light lenses. I thought it had a Torx type head but none would fit! Then just for the heck of it I used a square bit & BINGO!
