Created on:
Tools used
No Tools Needed
1. Handling the Bulbs
Note: DO NOT TOUCH the bulbs- the oil from your fingers will burn into the light and foul your bulb.
Clean with rubbing alcohol and a soft cloth if the bulbs do get touched.
2. Remove the headlight assembly
Pull up and remove the two anchor tabs.
Pull out the headlight assembly.
Unplug the harness.
You can access the bulbs and replace them from here if needed.
3. Install headlight assembly
Plug in the harness.
Put the headlight assembly back into place.
Clip it in with the two anchor tabs.
Close the hood and enjoy your new 1A Auto headlights.
Brought to you by 1AAuto.com, you source for quality replacement parts and the best service on the Internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts installed correctly. That's going to save you time and money. Thank you and enjoy the video. In this video, we show you how to remove and replace the headlight on this Buick Century as well as the headlight bulbs. No tools are needed.
Replacing the headlights bulbs and the headlights themselves, you can reach back here, but when you see how easy this is, there are two tabs right here, and all that you do is pull up on the tab and up on this tab. Then, you can kind of remove the tabs, set them here. The light pulls out and it disconnects from here. Now, you can access your bulb if that's what you need to do, or if your headlight's been wiped out by a rock or something like that, 1A Auto sells their replacement. It will be much clearer, brighter, and obviously re-installation is just as easy.
Plug it back in. You want the headlight into the fender. Push is back. Got to make sure these tabs come all the way through. They're in there, and then they push back in. Put your clip in, push it down. Back in, clip in, push down, and you're all set.
We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll free 888-844-3393. We're the company that's here for you on the Internet and in person.

Thanks 1A Auto
I received my new headlights in 3 days and the installation only took about 15 minutes. The alignment for the lights was done that evening and took about 20 minutes. They look great and driving at night is a lot easier.

The headlight assembly would have been nice but it was broke on the inside of it so it ended up costing me more to have it fixed
So easy

The installation of the two headlights was very simple and easy. All it took was pulling two holding clips on each lamp assembly and putting the new set into its place and inserting the two clips. That simple.
Great looking headlights.

I Ordered the headlights over the phone for my 1999 Buick. I was confident she helped order the right lights. Video made it easy to remove and replace the old lights. I was proud of A-1 Auto and myself.

Got the pair complete left and right assemblies for our 2000 Buick Century Custom. Easy to Install and clear. Great lights now. By the way these come with all bulbs already insralled. If you replaced your dim and bright and turn bulbs separately you would pay more. This way you have it all. Item's came fast

The product arrived exactly as described on the web site. After about fifteen minutes I had both headlights installed and they worked great. Installation would have been even quicker if the one mounting flange wasn't bent. I would recommend buying these.
Great job on those headlights

I totally impressed my family when I showed them my newly acquired mechanical skill by installing the new headlights on our old 1999 Buick. Couldnt have been so brave without the video however!! Makes the car feel like new!

I ordered these based on the how-to video and they were easy to install and worked perfectly. The car looks 100% better and the visibility at night is excellent. You will not be disappointed by these headlamps or the customer service at 1A Auto.

I ordered a set of two headlight assemblies. They arrived on time, and were in perfect condition. I installed them in less then 15 minutes. Not only did this fix my turn signal issue, but made the front of the car look like new. The old headlights had yellowed.I will definitely order from A1 in the future!

Dont get me wrong they improve the looks of the car tremendously. The only problem is they arent reflective enough behind the headlights. The yellow originals put out more light than the new ones. Im planning on returning them.

The headlights on my 2003 Buick Century had become cloudy and some of the insulation had come off the electrical wires. The new headlights I received from 1A Auto fit perfectly and are very clear. They give the front of the vehicle a new car look and work very well.

Shipping was fast! Product looks great. I put in new headlight bulbs but they do not shine properly, not bright enough and they shine a strange pattern on the ground and they shine too close to the car. The bright light bulbs are fine.
The blower resister was overpriced as I found out after purchasing.
I like your fast shipping and that the headlight units came in a pair for a great price.
Great Headlight Kit

I ordered the new headlights because I was tired of trying to clean them. The products sold did little to clear them no matter how much they were scrubbed. They came quickly, were easy to install and I can see clearly since my driving is before the sun rises and after dark. Absolutely Love them. Thank you Sam

The headlamps are poorly made as the insides of one lamp assembly is not secure and moves freely as assembly is rotated by hand , Unable to adjust either lamp to proper forward level with adjusting screw.
Great service

Great headlights. Adjustments up and down easy the left and right is ok. Not sure if they are adjustable even though they do have adjustments for it. Unable to get answers on that. Nor a video of it. But other than that they were perfect.
AMAZING!

Awesome product quality and very impressed by careful packaging to prevent breakage. Only thing I question is the necessity of replacing the "test bulbs" installed in lights. But have already recommended site to friends and will use again.

These were of course copies of the OEM parts, but the quality is very good and they even include extra screws, two per headlight bulb, to help retain the twist in fitting. They make the car look new again!

Drivers side worked partially. Passenger side was broken. Adusting screws broken. Received a replacement. Same issue. The zip ties are so tight they break the light from the inside. The zip ries may tighten with temp change. Called back too busy. Agree to have them retutn my call never happened. Next day same thing.
NOT THEVRIGHT PART, NOT THE FIRST TIME !
Perfect replacement lights

Shipping was super fast...
Product was shipped secure...
Instructions are written in an unfamiliar language but the images and few English words are pretty informative.
I am hoping that because of the bracing, that implies the lights are pre adjusted, let's hope..
Bulbs were included, so it was plug and play.
Removal and Install was maybe 5 minutes per side no tools required other than scissors or wire snips to cut two zip ties. Highly recommend.

Occasionally, manufacturers leave test bulbs in the lights. If you receive test bulbs, replace them with your original bulbs or with new bulbs.
