Understanding Your 2017 F-150 Lariat Headlights

Okay, so first things first, let's talk about the stock headlights that came with your 2017 Ford F-150 Lariat. These headlights are crucial for safe driving, especially at night or in poor weather conditions. Typically, the 2017 F-150 Lariat comes standard with halogen headlights, which are reliable and provide decent illumination. However, some models might have been upgraded with LED headlights, which offer superior brightness and longevity. Knowing what type you have is the first step in maintaining or upgrading them.

Halogen Headlights: These are the most common type. They use a tungsten filament enclosed in a halogen gas-filled bulb. They’re relatively inexpensive to replace and offer adequate light output for most driving conditions. However, they don't last as long as LED or HID headlights and consume more power.

LED Headlights: If your Lariat came with LED headlights, you're in luck! LEDs are much brighter and more energy-efficient than halogens. They also have a significantly longer lifespan, meaning fewer replacements. LEDs provide a crisp, white light that improves visibility and gives your truck a modern look.

Features of the 2017 F-150 Lariat Headlights:

• Automatic Headlights: Most 2017 F-150 Lariat models come equipped with automatic headlights, which turn on and off based on ambient light conditions. This is super convenient and helps ensure you never forget to turn your lights on at dusk.
• Daytime Running Lights (DRL): These lights are on during the day to increase your truck's visibility to other drivers. DRLs enhance safety and are a standard feature on many modern vehicles.
• Adjustable Beam Height: Some models may have adjustable headlight beams, allowing you to optimize the light projection based on your load and driving conditions. This feature helps prevent blinding oncoming traffic when you're carrying heavy loads.

Understanding these features and the type of headlights you have will make it easier to maintain and upgrade your lights down the road. So, take a quick look at your headlights to identify whether they are halogen or LED. This knowledge will be super helpful as we move forward!

Maintaining Your Headlights

Keeping your headlights in good condition is essential for safety. Over time, headlights can become cloudy or yellowed, reducing their brightness and effectiveness. This is usually due to oxidation from UV exposure and environmental factors. Here’s how to maintain your 2017 F-150 Lariat headlights and keep them shining bright.

Regular Cleaning:

• Why: Dirt, grime, and bug splatters can accumulate on your headlights, dimming their output. Regular cleaning helps maintain optimal brightness.
• How: Use a soft cloth and mild soap to gently clean the headlight lenses. Rinse with water and dry with a clean cloth. Avoid using abrasive cleaners, as they can scratch the plastic.

Headlight Restoration Kits:

• Why: Over time, the plastic lenses can become cloudy or yellowed due to oxidation. Restoration kits can remove this oxidation and restore clarity.
• How: These kits typically include sandpaper, polishing compounds, and sealant. Follow the instructions carefully, sanding the lens to remove the damaged layer, polishing it to restore clarity, and applying a sealant to protect it from future oxidation. This process can significantly improve the brightness and appearance of your headlights.

Bulb Replacement:

• Why: Headlight bulbs eventually burn out. Replacing them promptly ensures you have adequate illumination for safe driving.
• How: Refer to your owner's manual for the correct bulb type. To replace a bulb, disconnect the power, remove the old bulb, and insert the new one. Be careful not to touch the glass part of the bulb with your bare hands, as the oils from your skin can shorten its lifespan. Consider upgrading to LED bulbs for longer life and brighter light.

Checking and Adjusting Alignment:

• Why: Misaligned headlights can reduce visibility and blind oncoming drivers.
• How: Park your truck on a level surface facing a wall. Measure the height of your headlights from the ground and mark the same height on the wall. Turn on your headlights and check if the beams are aligned with the marks. If not, adjust the headlight alignment screws until the beams are properly aligned. If you're unsure how to do this, consult a professional mechanic.

Protecting Your Headlights:

• Why: Prevention is better than cure. Protecting your headlights from UV damage and environmental factors can extend their lifespan.
• How: Apply a UV protectant sealant to the lenses after cleaning or restoration. This will help prevent oxidation and keep them clear for longer. Consider using headlight covers or films for added protection, especially if you live in an area with harsh weather conditions.

By following these maintenance tips, you can keep your 2017 F-150 Lariat headlights in top condition, ensuring safe and clear visibility on the road. Regular care not only improves safety but also enhances the overall appearance of your truck.
