I bought the Xenondepot Phillips LED bulbs for the license plate bulbs and they look great at night. I like it because it runs with lower power and are brighter. The LED bulbs are the same ones you would use for the vanity mirror doors and map lights. Go for it! super easy to install just unscrew two screws and pull bulbs out. I also replaced my back up lights with the Xenondepot Phillips bulbs both the license plate bulb and back up light bulbs caused no glare on my rearview camera instead they made the camera look like it was a night vision camera it picks up a lot of detail in reverse pitch black.
Other than the great looks I bought them for the safety part that you just mentioned. They do provide much more detail at night which makes to easier for me to see things vs possibly backing up into them. Scratched up bumper vs $15 bulbs....I think I made the right choice.
