Had to make a run this evening after dark and remembered to take a few pics of the backup lighting using the above mentioned LED replacement bulbs.
I have a third reverse LED light down low in the bumper facia. I have it taped off in one of the pics so that you can see the vast improvement in stock lighting over OEM backup bulbs.
Backup lighting with third reverse LED backup and brake lights on:

Finally, new LED backup lights only:
As you can see, plenty of bright white light, even projecting off to the sides. I'm at the bottom of my driveway, which slopes upward.
These bulbs are even brighter then the LED ones that I had in there originally.
Have a good day.
