When you put a third generation (2015-2023) Toyota Tacoma in reverse at night, the backup camera shows... not much, because the license plate lights are angled up and shine straight into the camera lens, causing glare and weird exposure issues.

These simple little plates attach with some double sided tape, and block the glare from the lights. This greatly improves the view in the backup camera while still allowing the license plate to be illuminated.

You need to print two, and preferably print them in some UV stable material so they last longer outdoors.

Edit: New version is two millimeters longer to better block glare especially on right side.
