Those projector headlights you buy off Amazon or eBay are JUNK!! They say the Gen 4s are the best. But nothing beats a good retrofit into the stock headlights. Even the Mini H1s will blow those eBay projectors out of the water. I have EvoX-R projectors now and I can see for about a mile with those. Also, go with 4,300k if you want the brightest light output. Better yet, go with a projector that takes a D2S bulb, like the EvoX-R and spend the extra money on Philips 85122 bulbs. They have just a tinge of yellow to them, but I love 'em.
