Review on SUMK Sequential LED Rear Bumper Reflector Brake Tail Light Turn Signal Lamps for Tesla Model 3 (2018-2021) - Super Bright Red LED Strip Light Bar by Noah Lewis

Quality consistent signal light replacing the boring reflector. I followed the installation instructions from the Tesla DIY YouTube channel, which doesn't require removing the rear bumper, which is quite difficult. If you have skinny forearms you will find it easier than me as the space is very tight! Inserting the connector plug through the tiny reflector hole is difficult and I had to use a small Allen wrench on the outside of the hole to align the connector so it came straight out of the bumper. Also, the hardest part is removing the old reflectors. I used some plastic auto trim levers and still broke one of the reflectors (but it still ended up in the bin). You may get best results with two pry bars working in sequence from the outside of the bumper toward the center. The reason they don't get 5 stars is because as advertised they are supposed to flash when I apply the brake, but mine just does the standard sequential flashing process when I apply the brake (see video). Very happy with the update!
