Are your Mustang headlights lighting up everything but the road in front of you?? Watch this video as Jmac shows you how to adjust your headlights. No more lighting up the ditch and blinding birds in the trees while cruising in your Stang at night. We cover how to adjust head lights for 87-04 Mustangs. Be sure to check out all our lighting install videos for help with installing your new headlights.

No matter what year model Stang you are going to adjust, you need to make sure you stage up your Stang properly to ensure you get proper alignment. It is best to do this at night when it is as dark as possible. You also need to make sure the ground is as flat and level as possible. Start by placing the nose of your Pony as close as possible to the flat wall you will be measuring against. With your Pony in park or out of gear with the e brake engaged, you can now turn on your lights. Take some tape and mark off the horizontal and vertical centers of each light beam. With the centers of each beam marked you can now move your car back 25 feet.

For the 87-98 Mustangs, you will need a headlight adjusting wrench, part number LIS-14540, to adjust the lights. Use this tool to fine-tune both the verticle and horizontal beams. You will want the center of the headlight beams to be just down and to the right of the original center beam tape marks. On a 99-04 Mustang, there is no need for a special wrench or tool. All you need is a Philips head screwdriver to make your vertical and horizontal adjustments. Use the same adjustment method as the 87-98 and have the beam down and to the right of the original tape marks.

JONATHAN MCDONALD: So you've replaced the headlights in your Mustang, and your first time out driving at night reveals that they really don't light up the road at all. It's definitely not a light transmission problem. It's all about the adjustment, or lack thereof. Just because your new headlight's bolted right in, doesn't mean you're done with the install. If you own an '87 to '93, '94 to '98, or '99 to '04 Mustang, we're going to show you how to stage your car up for the adjustment procedure, what you're going to need, where the adjusters are, and what they do.

First and foremost, what you're going to want to do is find you a place that's going to be as dark as possible, flat level ground. Move your car all the way up against that wall or door as close as you can get it without touching. Turn your headlights on.

Grab you some blue painter's tape or something equivalent. Any type of masking tape will work. Make you a horizontal tape line across each one of the light beams and make you a vertical tape line across the center of each one of the light beams. Now move your car back 25 feet.

Now a handy tool to have in your arsenal is this headlight adjusting wrench. It'll work on '87 to '98. On an '87 to '93, here's where your horizontal adjuster is and here's where your vertical adjuster is. Go ahead and use your tool to either move the adjuster in or out, depending on where the beam is pointing at. And you want that beam to land, final adjustment, where the beam is just down and to the right of where your tape lines intersect.

On a '94 to '98 Mustang, remove your radiator cover so you can have full access to your inside adjusters. Here's your horizontal adjuster and here's your vertical adjuster. Adjustment process is the same as it was on the Fox body.

On a '99 to '04 car, man, they made it a whole lot easier. It is super simple to adjust these headlights. All you need is a Phillips' head screwdriver. Here's your horizontal adjuster and here's your vertical adjuster.

Go drive your Mustang and enjoy the clarity of having properly adjusted headlights. Go on over to and check out more Mustang lighting solutions.
