I personally am not a fan of the ebay halo light on a muscle car......my opinion would be to ditch them and just go with a brighter standard colored light.
I kind of like these because they make my car look cool at night when I am at a cruise in at dusk. I do not even drive the car at night so it wouldn't really matter that these are Halo lights. I have had the sealed beams and still have a set but I like these for effect on my car. They just look cool on a blue painted car.
