We went with a Bi-Xenon Projector (Low and High Beams) since the existing headlight was a single bulb 9007 setup.
We covered the projector with a modified Apollo shroud and kept everything chrome on the inside.
On the back end, he received Morimoto 6000k D2S bulbs, powered by New Morimoto 35watt 'Blue' Ballasts, and a Morimoto-Control wiring harness so everything is firing perfectly.
These will allow him to be MUCH safer at night (being able to see further and wider than stock) all while looking as OEM as possible.
