I bought a 12pc set from BlueOval. Nice lights, been on little over a year now with no yellowing or condensation build-up. I did run a bead of flowable silicone sealant around the seams though.
Yeah i've got those headlights also. It does take some time to get them adjusted but they do adjust pretty nicely. Park on flat ground pointing at a flat wall in the pitch dark and start adjusting. Take it for a test drive and see if they're to low or high, if so, pull back up to the wall and make the proper adjustment. After a few attempts you'll have them perfect.
