How Headlight Bulbs Are Sized

Every vehicle uses a specific bulb size for each headlight position. The most common sizes you'll see are:

Single-Beam Bulbs

These use one bulb for low beam and a separate bulb for high beam:

Dual-Beam Bulbs

These handle both low and high beam in a single bulb:

Fog Light Bulbs

Fog lights are a separate position, usually below the main headlights:

Quick Reference: Popular Vehicles and Their Bulb Sizes

Here's a quick-reference chart for some of the most popular vehicles on the road. All data verified against OEM specs and multiple aftermarket sources.

Trucks

SUVs

Sedans

Important: Some vehicles have different bulb sizes depending on the trim level. Higher trims (like Platinum, Limited, or Touring) often come with factory LED headlights that can't be replaced with aftermarket bulbs. Use our headlight bulb finder to check your specific trim.

Watch Out: Factory LED Trims

This is the most common mistake people make. Many newer vehicles offer both halogen and LED headlights depending on the trim:

Example: 2020 Toyota Camry - L, LE, SE → Halogen (H11 low beam, 9005 high beam) ✅ Upgradeable - XLE, XSE, TRD → Factory LED ❌ Not replaceable

Example: 2020 Ford F-150 - XL, XLT → Halogen (H11, 9005) ✅ Upgradeable - Platinum, Limited, Raptor → Factory LED ❌ Not replaceable

Factory LED headlights are integrated units — the entire housing contains the LED module, and you can't swap in a replacement bulb. If your vehicle has factory LEDs, you're already running the brightest option available from the manufacturer.

How to tell: Look at your headlight housing. Halogen headlights have a removable bulb with a twist-lock base. Factory LED headlights are sealed units with no user-accessible bulb.

LED vs. Halogen: Why Upgrade?

If your vehicle came with halogen headlights, upgrading to LED is one of the easiest and most impactful modifications you can make.

Modern LED headlight bulbs are designed as direct replacements for halogen bulbs. Same base, same connector, no wiring modifications. You literally twist out the old bulb and twist in the new one.

How to Find Your Exact Bulb Size

Method 1: Use Our Headlight Bulb Finder (Fastest)

Enter your year, make, and model. We'll show you: - Exact bulb sizes for every position (low beam, high beam, fog light) - Which LED upgrades fit your vehicle - Whether your trim has factory LED (not upgradeable)

Method 2: Check Your Owner's Manual

Your owner's manual has a "bulb replacement" section that lists every bulb size. It's accurate but doesn't tell you which LED replacements will work.

Method 3: Pull the Bulb Out

Pop the hood, reach behind the headlight housing, twist the bulb out, and read the part number printed on the base. This is the most reliable method but requires getting your hands dirty.
