This is what I did. It doesn't have any bling value. However the lighting is amazing compared to the sealed beam stuff. The aftermarket HID stuff while bright doesn't have a good beam pattern and can actually hinder your visability without the correct projector housing, and those are some coin! There are people who make a 7" round light and retrofit projector housing.not the cheap eBay housings but usually TSX housing or something like that.

My Hella H4 upgrade took about 45 minutes with having to go find two new headlight adjusters.
