Review on JDM ASTAR High Performance Super Bright 1:1 Design 3020 Chips 7440 7441 7443 7444 992 White LED Bulbs: Illuminate with Supreme Brilliance! by Tom Schuster

A huge improvement over the "standard" dull yellow reversing lights. I'm either very lucky or the polarity doesn't matter with these LEDs as both worked on the first test. I replaced some of the interior lights with LEDs and if I had to turn them off and swap them out or not it would be hit or miss. FYI I have a 2019 Tundra and it doesn't cause lamp errors and they didn't need it. additional resistors, etc. to "fool" the computer, which may be necessary for blinkers.
