2004–2008 Ford F-150 Headlight Bulb Sizes & LED Upgrade Guide

If you own a 2004 to 2008 Ford F-150, chances are your truck still uses its original halogen headlights. While these bulbs were standard at the time, their output can feel underwhelming by today’s visibility and safety standards—especially when driving at night or in foggy conditions.

The 2004 to 2008 Ford F-150 models all use the same headlight setup—an H13 (9008) halogen bulb that combines both high and low beams. So whether you're checking the 2004 Ford F-150 headlight bulb size, replacing a 2005 F-150 headlight, or upgrading the 2007 model, the same bulb type applies.

This makes it easy to upgrade to LED. Plug-and-play kits are available for all years, with no need for wiring changes. And knowing the right bulb size from the start helps avoid flickering, poor fitment, or dim output.

Headlight & Fog Light Bulb Sizes for 2004–2008 Ford F-150

Interior upgrades are popular among 2007 F-150 owners looking to modernize their cabin lighting while reducing heat and battery draw.

2004–2008 Ford F-150 Headlight Bulb & Fog Light LED Upgrade

The stock halogen headlights on the 2004–2008 Ford F-150—particularly on trims like XL and XLT—often struggle to provide enough visibility during night driving or bad weather. These models use an H13 (9008) dual-filament bulb for both high and low beams, and H10 or 9140 bulbs for the fog lights, depending on the trim.

Upgrading to LED is a smart move for both performance and appearance. LED headlight kits offer up to 300% more brightness than factory halogens, a cleaner beam pattern, and a cooler color temperature—perfect for modernizing the look of your 2004 or 2008 F-150 headlights without changing the housing.

For fog lights, an LED replacement improves contrast and low-road visibility, especially in rain or fog. If you’re looking for a plug-and-play solution that fits these trucks perfectly, Hawkglow’s LED headlight and fog light kits are built to match the F-150’s factory specs, ensuring a smooth, error-free installation.

Whether you're driving a 2004 Ford F-150 or a later 2007 or 2008 model, this upgrade is one of the simplest ways to enhance safety and style with minimal effort.

Installation Tips for LED Bulbs on 2004–2008 Ford F-150

Upgrading your F-150 headlights or fog lights to LED is typically a plug-and-play process. Most 2004–2008 models allow for bulb replacement without removing the headlight housing.

Here are some quick tips for a smoother install:

• Turn the front wheels outward to access the back of the headlight housing through the fender liner.
• Disconnect the battery before installation to avoid short circuits or electrical errors.
• Remove the dust cover, twist out the old halogen bulb, and insert the new LED.
• Test the LED before sealing—if it doesn’t light up, flip the plug to correct the polarity.
• Secure any external CANbus decoders away from heat or moving parts.

With basic hand tools, most users can complete a full headlight and fog light upgrade in under 30 minutes per side.
