Perfect fit for the right price
I recently purchased a 2001 Mercury Grand Marquis for $1,000 and didnt want to put a ton of money into it due to the amount of miles, but the headlight assemblies were pretty cloudy and I didnt 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.

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 elses 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
The product fit great I can now see the road. The price was right and you cant beat the quick delivery. I applaud the person who took my order as she informed me of a very important detail about the product. That was to remove the test bulbs, that when left in can cause problems. Refreshing to find a person that knows their products. I have used other car part companies and I was pleasantly surprised with this one being a cut above. Thanks, Jim

J G April 4, 2016
I received my new headlight with headlamp bulbs included. Turn signal bulbs were not included.
Kevin E April 4, 2016
The headlights are built in, the only bulb that is not included is the yellow parking light.
Dan B April 4, 2016
Our lights may not include the bulbs. You may be able to reuse your original bulbs. If bulbs are included they may be test bulbs and may not have the longevity of a new bulb.
Brian F April 4, 2016
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).
Lynn W April 4, 2016
the four different ,two car and two truck units came with head lamp bulbs but not turn and marker bulbs.
