Fine Business!
Headlight assemblies came quickly and installed fairly easily. They look great!
I have two suggestions: 1. Include in the package a reference to the wonderful 1A Auto videos for those who may not be familiar with the videos..
2. In the headlight assembly video point out that there are index protrusions on the holes that require the adjusting screws to be turned to match. I had to watch someone else's video to discover that. (Being older I was trying to install without getting down on the ground. I find getting down is easy, it is getting back up that is hard!)
Thanks for a quality product at a reasonable price!

Perfect fit for the right price
I recently purchased a 2001 Mercury Grand Marquis for $1,000 and didn't want to put a ton of money into it due to the amount of miles, but the headlight assemblies were pretty cloudy and I didn't have the time to put into trying to buff them out. I found these for under $70.00 and they fit great and look awesome.

why aren't bulbs included?

BEST ANSWER: Actually mine came with bulbs included, and have been working fine. I was replacing the OEM set on which the lenses had become foggy, so I could have swapped in the old bulbs too (i.e. they were not damaged).
