Here are my blue Led lights that some members were requesting pictures of, my camera doesn't have night mode. The blue lights are a lot brighter than in person, but still not as bright as White Leds.

My fog light is super white xenon though.

Not a fan of the blue on the license plate either, I have a pair of white ones, I just have been too indolent to change them yet.
