Stay clear from the 'one piece' projector lights and really all projector lights for 1st gens. Take it from me, I've owned several sets of aftermarket headlights from the Spyders to the ANZOs and all in between, and I would say without a doubt that all the Projector headlights on the market for the 1st Gen Expedition are complete and utter junk. Don't get me wrong some of them look cool but the components are cheaply made, the LED 'DRLs' on the 'CUSTOM' headlights need to be wired into your parking lights by splicing them in which is a pain in the ass, not to mention how temperamental the LEDs and CCFLs are as they'll stop working at random because of the terrible gauge of wiring throughout the headlight and not making contact, not to mention the LEDs aren't bright at all and are barely noticeable during the day. And lets not forget about the Projectors, they are cheap unfocused and often times you cant raise or lower the beam pattern without raising the whole headlight which is just dumb for a projector headlight. In addition you get to swap your tried and true dual beam 9007s for H1 bulbs which produce possibly the most woeful amount of light I've ever seen... Seriously even after adjusting the headlight for maximum light I could only get around 17 feet of light out of these projectors ahead of my Expy, so i ended up ******* everyone off by driving with my highbeams instead. And god forbid you put HID's in these cheap ass headlights because the sheer amount of heat will warp the cheap plastic interior of the lights and possibly the lens of the headlight and lens of the projector which f***s you completely. And then finally we get to the fitment, oh boi... which is downright terrible as don't fit flush with the grille because they bulge out the sides and weren't sized correctly by the idiots at 3d Modeling, its as though they never did a test fitment at all while designing them and as such they are an absolute pain in the ass to get the locking bolts in place. Those projector lights are a shit show, don't buy them.
That being said if you're dead set on projectors I would suggest buying a set of the Lighting Style headlights, the same ones that jkroten and tekrsq have on their Expys (which are great reflector lights in of themselves), and having a shop retrofit Quality Projectors into them with HIDs or LEDs to get that clean cutoff line great output and fantastic down-road light.
All that being said again, I still would highly recommend DEPO and REPLACE as they make great 'OEM' and 'Lightning' style lights for the Expy.
As for myself, I have the 'Diamond Cut' reflector headlights by REPLACE with LEDs as opposed to Halogens and they work fantastic for me. If you have any questions don't be afraid to ask.
TL;DR
Don't buy projector headlights for your Expy, they look cool but they suck.
If you really want Projectors have someone professionally Retrofit them into some solid headlights, Be warned it will cost $$$.
Stick with Reflector headlights from good companies like DEPO and REPLACE and put some solid bulbs in them and they'll work great.
