On one of our five bricknoses I plan to do this swap I just haven't figured out which one yet. It will also be HID retrofitted like Evan did on his truck.

Right now I just have a headlight relay on my 88 F150 and it is brighter then our other bricks but our 90 F150 has some pretty decent headlights. Also try looking into different bulbs. All of our bricks except our 89 F250 have Sylvania super white or something like that and the only reason the 89 F250 doesn't have it is because it is just a beater truck and my auxiliary lights on it make up for it.
