2007 GMC Sierra Classic Headlights (Specs and Features)

The 2007 GMC Sierra Classic Headlights are a very popular option for those looking to upgrade their vehicle's headlights. The headlights themselves are a direct replacement for the factory headlight assembly.

They have an H-11 type bulb that is easily replaceable with a standard 1157 bulb. The headlights are made of high-quality materials, and they’re designed to last.

They also have a sleek design that makes them look good on any GMC Sierra Classic. The headlight assembly is designed to be user-friendly, with an easy installation process.

These are reliable headlights with solid road coverage and visibility. Below are some of the most notable specs and features for the  2007 GMC Sierra Classic Headlights.

Drop-In Fit

The drop-in fit is one of the best things about this truck and the compatible headlights. There is no complex construction, and the lights can slide right in during installation for a tight fit for anybody to install.

The replacement lights come with an exact fit too, so no modifications or customizations are needed. They also come with a lifetime replacement warranty.

High-Quality Visibility

The other amazing thing about these headlights is the visibility they provide. Whether using high beam or low beam installs, they work well to provide a wider visual in front of the vehicle in dark driving conditions.

The bulbs are also available in various colors like golden yellow, bright white, lightning blue, ice blue, and deep blue. GMC Sierra owners can expect improved illuminations and much better light distance too.

Adaptive LED Bulb

This is the most common type of bulb that people use in their vehicles, so it's easy to find one if you need to replace it or if your current one burns out. The adaptive bulb provides excellent visibility and coverage.

These headlights also have very durable housing made of steel and plastic, which helps with long-term durability and reliability. Drivers of this truck can expect long-term durability because of how strong this bulb is.

The adaptive bulb can be changed out for different colors and brightness levels, but the most common bulb type is the 9005 high beam bulb and 9006 low beam bulb.

Fast & Easy Installation

The beauty of classic GMC Sierra headlights is that they’re simple to install. The process doesn’t require any special tools or professional help, and it can be done in about 10-15 minutes after the first try.

All that’s needed is a Phillips-head screwdriver to open and remove the existing light and replace it with the new one. They also come with a drop-in fit on other models besides the 2007 so they’re compatible with other trucks.

Durable Plastic Lens Material

The durable plastic lens material is one of the most important features Sierra Classic owners can expect from these headlights. They hold up well year round with a special surface coating for a scratch proof finish.

They also display excellent impact resistance, making it difficult to break the plastic cover. They are fully sealed with a corrosion resistant and dust resistant design.

FMVSS-108 Compliant

These headlights are also FMVSS-108 compliant, meaning they are designed based on the rules and requirements in place by the Federal Motor Vehicle Safety Standards.

What Headlight Bulbs Are In A 2007 GMC Sierra Classic?

The primary headlight bulb used in the headlights for all 2007 GMC Sierra Classic models is the Sylvania 9006 Basic Halogen Headlight Bulb. This is a cheap replacement option but with many features to offer.

The Sylvania 9006 Basic Halogen Headlight Bulb is a long-lasting headlight bulb that offers superior performance. It provides a brighter and whiter light, improving visibility at night and in bad weather conditions.

It also provides you with an intense beam pattern than other bulbs of the same type, making it easier to see on the road ahead of you. It’s also DOT-approved, so it’s perfectly capable of meeting all Sierra Classic standards.

How To Replace 2007 GMC Sierra Classic Headlights

Replacing the headlights on your 2007 GMC Sierra Classic is not easy and requires a little bit of knowledge about the truck. Having some tools handy is also helpful.

Following these steps and having some basic tools will make it a fast and easy fix to replace the headlights without any problems.

1. Open The Hood

First, locate the lever inside the vehicle to open the truck's hood. This will release the hatch, and the hood can be lifted and propped open to allow for two free hands to work on replacing the headlights.

2. Locate The Headlight Retaining Pins

Next, the headlight retaining pins should be located. These pins are responsible for holding the headlights in place, allowing for proper visibility while driving even on uneven or bumpy roads.

Without the pins, the lights could come loose causing a bad connection. This is a common reason why headlights go out before the light has gone bad.

3. Rotate The Pins

To remove the existing headlight so it can be replaced, the retaining pins need to be rotated until they come loose. Once they are loose enough the pins should be removed.

The outer pin always turns outward and there is an inner pin that should be turned inward. Simple enough, but once the pins get loose pull them out and set them aside for later.

4. Remove The Headlights

The headlight assembly must be replaced to replace the GMC Sierra Classic headlights. The wiring harness from the old lights also needs to be disconnected.

This also depends on whether the entire headlight needs to be replaced or just the bulb. However, the wiring harness needs to be removed either way.

5. Remove And Replace The Bulb

After the headlights are removed, the old bulbs can be removed and replaced. Rotate the bulb counterclockwise to remove it from the assembly and have the new bulb ready for installation.

6. Insert New Headlight

The new headlight and bulb can be installed using the drop-in fit method. These lights are designed for fast installation, so the bulb can be installed before even installing the headlight.

If only the bulb needs replacing, leave the headlight installed and simply rotate the bulb clockwise until it’s securely installed.

7. Connect The Wiring Harness

After installing the new headlight and bulb, the wiring harness needs to be connected again. This can be done before locking the headlight assembly into place to give the installer the best angle to make the wire connection.

8. Insert The Headlight

After the wiring harness is connected, the headlight can be installed again. Start by locating the retaining pins and securing them back into the same place as before.

They should be rotated the opposite way this time until they are locked in securely. The headlight should have no room to move at all, and this is critical to avoid any damage or disconnections while driving.

9. Test The New Headlight

Lastly, the headlights on any vehicle should always be tested before putting everything back together. The same is true for the 2007 GMC Sierra Classic.

Turn on the vehicle and headlights to see if they are working. Always try to turn on the high beams to confirm everything is in order. Once this is complete, everything can be closed and the truck is road ready again.

How Long Do 2007 GMC Sierra Classic Headlights Last?

Regarding headlights, it is important to consider how much light they provide and how long they will last before replacement is necessary. The average headlight bulb lasts 500 to 1,000 hours, but we expect these bulbs to last over 1,000 hours.

The 2007 GMC Sierra classic headlights provide up to 300 lumens, which means you can see further than before while driving in low-light conditions such as fog or dusk.

When it comes to headlights, it is important to consider how much light they provide and how long they will last before replacement is necessary.

The 2007 GMC Sierra classic headlights provide up to 300 lumens, which means you can see further than before while driving in low-light conditions such as fog or dusk.

The key to making these lights last longer is regular checks and maintenance. This ensures the connections never come loose and any potential problems get caught before they ruin the headlights for good.

This includes taking care of the polycarbonate lens, because over time it can get foggy or develop small cracks from excessive sunlight exposure.

Are These Headlights Compatible With Other GMC Sierra Classic Models?

Headlights on a car are one of the most important parts of a vehicle. Not only do they provide light, but they also serve as a safety feature.

They are an essential part of any car and should be replaced when they need to be replaced. And this brings up the debate about the headlights on each GMC truck model and how much they differ.

GMC Sierra 1500

The current GMC 1500 is similar to the GMC Classic, which was the same style truck but with a different name because of a few changes from previous generations. Today, the 1500 model is one of the most popular truck types.

Because of the design similarities, the headlights used are similar to the 2007 Classic. The primary difference is the size used, and all trucks from 2014 to present-day use a different size, so the same headlight won’t be compatible.

GMC Sierra 2500

The GMC Sierra 2500 has similar headlight compatibility and the same fit, but they tend to use more advanced headlights. The most popular option is the Xenon HID headlights and they are available in various options.

This includes low beam and high beam kit styles or a fog light conversion kit. All three options provide excellent visibility with German Technology AC Xenon Bulbs and easy to install wiring and mounting equipment.

They also come equipped with German Technology AC Digital Ballasts to supply HID bulb power. The ballasts can be changed based on their desired power and lifespan of the headlights.

GMC Sierra 3500

The GMC Sierra 3500 uses a similar design as the 2500 and there are various options to consider for this massive truck. We prefer the Halogen bulbs and headlights for this truck but the differences are small.

All kits for this truck come with a 9005 high beam bulb and 9006 low beam bulb. This includes DOT fully certified designs with both driver side and passenger side lights included.

They are versatile and fit other trucks like the GMC Yukon and XL too.
