You have a good radiation pattern. However, they are in the yellow light spectrum and not in the white as promised. But in general they have a good radiation pattern and a pretty decent distance. I used them in an old car with dim headlights. You changed the situation. But if you buy them, only Silver Star Ultras, don't buy ZXE, they're not worth it. They give off the same color, and a solid blue tint with no increase in power just blocks the light. If you want blue/white light, better switch to HID or LEDs (with ballasts). Ultras are good, they have a slight blue cast to whiten the light. In general I am very satisfied.
