I installed Morimoto H1 Bi-Xenon projectors last weekend with DDM 5000 HID bulbs. Once you get past opening the headlights up, the install is very easy. I think they look great in the daytime and night time. I think I should open the lights back up and fix a small rotation issue, but they aren't off too much. The light output at night is better than stock, but I was expecting a little bit bigger difference. I think that the TB lights are really not that bad stock, so that is why the light isn't blowing me away. My wife has a 2008 civic that I will be putting these in next, and it is very hard to see at night because the lights are so bad. So I think in a car like that the difference will be very noticeable. For the $100 I spent I think its a great mod, and now I have true quad high beams.
