More important than your light output is how you focus that light. Hella from Germany is king when it comes to lighting. When you put the HID bulbs in a housing not designed for them you throw a lot of scattered light where you don't want it and it's very hard for on coming traffic to see. The idea is to focus the light on the road and not where it will reflect back into your eyes when driving especially in rain, fog or snow. If you're going to run HID's in a non HID housing on the street I suggest you trade drivers with a different car, drive at them from the opposite direction and see how you like it. I've seen these from behind me and from all the way across the beltway (6 lanes and the medium strip) and its BS. Now put that same bulb in the properly designed housing and I'm fine with it because it's properly focused. I.E. Audi, BMW, Lexus etc.. Motorcycle guys, I feel for you but Hella makes single round light assembly's for older bikes, off road or boat, whatever, just remimber if something is coming at you, he probably can't see. LED's are great, different ball game.
