Thanks to the replies I got in this thread (post #28 and on): http://www.f150forum.com/f83/headlights-157321
And to Tony at 1AAuto I've got some nice looking new lights on the rig.
Light output isn't anything special and is on par with the factory units,
but I'm going to help them out a bit with Sylvania Silverstar Ultra bulbs which just went on sale locally.
"Eagle Eye" is the actual brand name (I knew they were a replica and not original), but the quality is pretty good, especially considering the price.
So far so good.
I think they give the front a lot cleaner look.
I'll try and get the new bulbs in shortly and get some actual nighttime shots of the light throw on the road.
