I think they are fine as far as brightness is concerned. Compared to a xenon bulb, the intensity/color of the light is not the same. However, compared to a standard halogen sealed beam it's about 2x brighter and whiter, because of the bulb and 10x more focused because of the hella lens. with the lamps adjusted correctly, it is more than enough for me, the sharp cutoff of the light pattern takes some getting used to but I like it. It definitely will show the weakness of the stock charging system especially at idle. I would like to do a HID conversion eventually, but that is pretty far on the back burner right now.
