Knight Rider lights :)
Check out what my lights look like from the video cameras at work when I remote start my car. I go out and look at them are they're normal, constant on. I think it's cool. Wish they had made them this way

Gary, I think I know what you're saying. The lights appear to flicker very fast on the video. It was explained to me that it has to do with the way LED light operate. The light stream from an LED is not steady like the old style bulbs, the light stream actually flashes at a speed unnoticeable to the human eye. But, it can be picked up on video. Now mind you, this is what I heard. I'm old , and could have explained it wrong. But, I'm sure I'm close enough for you to understand what is going on.

This is how brightness is controlled in LEDs. You cycle it on and off at an extremely high speed to make it appear more or less bright. Even if you don't necessarily need them to be dimmed, you can still cycle them below their "fully on" threshold to help extend the lifespan of the unit.
