H11 Headlight Bulbs for Low Beams, Fog Lights and HID Upgrades

The H11 bulb is a single-beam bulb commonly used for low-beam headlights and front fog lights in many modern vehicles. In factory halogen form, it typically operates on a 12V DC system, features a PGJ19-2 twist-lock base, and uses about 55W of OEM power. Before upgrading to LED or HID H11 bulbs, always ensure there is enough space behind the headlight, as the upgrade may require extra parts such as heat sinks, fans, igniters, or additional wiring. Housing depth and dust-cap clearance are important before upgrading. Standard H11 halogen bulbs typically emit a warm white light at around 3200K, while LED and HID upgrades can deliver brighter light, cleaner color, and better road visibility depending on the kit. Since H11 bulbs work with both projector and reflector housings, proper alignment, focal accuracy, beam pattern, and thermal control all matter.The housing controls glare and beam spread, while the bulb affects output, color temperature, startup behavior, and electrical compatibility.

This makes H11 bulbs more sensitive to upgrades, especially when switching from traditional halogen to LED or HID technologies. For a smoother install, follow the H11 bulb installation guide before replacing your factory bulbs.

Key LED attributes include:

  • 6000K white color temperature for daylight-matched clarity
  • 3000K yellow variants for reduced backscatter in fog and rain
  • Lower power fluctuation than halogen or HID
  • Integrated CANbus load management to prevent bulb-out warnings

How to Choose the Right H11 Headlight Bulb

Our lighting experts are here to help you find the perfect H11 LED headlight upgrade for your vehicle. Whether you're replacing dim factory bulbs or looking to update your lighting performance, finding the right bulbs is simple.

Check your headlight bulb type in three quick steps:

  1. Confirm your vehicle uses H11 bulbs: Check your owner’s manual, existing bulb number, or vehicle fitment details before ordering. H11 bulbs are commonly used for low beam headlights and fog lights, but the exact position can vary by vehicle.
  2. Know whether you need headlights or fog lights: Choose H11 LED headlight bulbs for low beam upgrades and H11 fog light bulbs for bumper-mounted fog light positions. Fog lights and headlights have different beam purposes, so make sure you are replacing the correct bulb.
  3. Choose LED, HID, or halogen replacement: H11 LED bulbs are popular for a bright light output,  modern look, and plug-and-play upgrades. H11 HID bulbs or HID kits are used for compatible xenon-style setups, while H11 halogen bulbs are closer to factory-style replacements.
  4. Pick the right color output: For headlights, 6000K white is a popular choice for a clean, modern appearance. For fog lights, 3000K yellow is often preferred for fog, rain, snow, and low-visibility driving.
  5. Check housing clearance: Some H11 LED bulbs require extra space for ballast, wiring, and additional fans. Make sure there is enough space behind the headlight or fog light housing before ordering.
  6. Look for CANbus or anti-flicker support if needed: Some vehicles may experience flickering, warning lights, or bulb errors after upgrading to LED or HID bulbs. CANbus-ready or anti-flicker H11 bulbs can help reduce these issues.
  7. Replace both sides together: Always replace H11 bulbs in pairs to keep the brightness, color, and beam appearance even across the front of the vehicle.

H11 LED Headlight FAQs

The brightest options are almost always high-output LEDs, which easily outshine the halogen bulbs your car probably came with. Depending on the kit, some H11 LEDs can hit around 10,000 to 12,000 lumens per pair.

That said, chasing raw lumens isn't the whole story. A good bulb also needs proper beam focus, correct chip placement, and steady cooling. Get those right, and you'll actually see the road better, without blinding oncoming traffic with glare.

It depends on what you're after. Brightness, cooling design, CANbus compatibility, and whether you're lighting up your headlights or fog lights all move the price around. As a general guide, most H11 LED headlight bulbs at Underground Lighting land somewhere between $50 and $150+ per pair.

Most of the time, H11 is a low-beam bulb. But plenty of vehicles also use it for fog lights or other forward-facing positions, so it really comes down to how your headlights are set up.

Before you order, it's worth a quick check of your owner's manual, your current bulb number, or your vehicle's fitment details to confirm exactly where that H11 lives, low beam, fog light, or somewhere else.

Loads of them. You'll find H11 bulbs across cars, trucks, and SUVs from Toyota, Honda, Subaru, Volkswagen, Ford, Chevrolet, GMC, Hyundai, Kia, Nissan, and plenty of other brands.

One thing to keep in mind: fitment can change with the model year, trim, and lighting position, so don't go by brand alone. Always confirm the exact bulb size for your specific low beam, fog light, or headlight position before checking out.

They look alike, but no, they're not interchangeable. H11 and H9 bulbs have different wattage ratings, output levels, and application requirements. An H9 usually runs at a higher wattage, so swapping it in where an H11 belongs isn't a good idea unless your vehicle and housing were built for it. Stick with the bulb size listed for your car, and you'll avoid fitment and electrical headaches.

Originally, yes. H11 started life as a halogen bulb, and a lot of vehicles still roll off the line with H11 halogens today. But the H11 you buy now comes in halogen, LED, and HID versions.

So if your car currently runs factory halogen H11S, upgrading to an H11 LED bulb or an H11 HID kit is usually on the table.

In most cases, yes, as long as the bulb size and housing line up. A plug-and-play H11 LED is made to drop into the original H11 socket and connect straight to your factory wiring.

A couple of things to watch for: some vehicles want CANbus-ready bulbs or anti-flicker decoders, and because LED bulbs often have built-in fans or heat sinks, you may need a little extra room behind the housing.

Absolutely, H11 is a common fog light size. If that's what your vehicle uses, you've got options. White H11 LED fog light bulbs give you a clean, modern look, while yellow H11 fog light bulbs are the go-to for cutting through fog, rain, snow, and other low-visibility conditions.

Just double-check that your fog light housing actually takes H11 before you order.

For headlights, 6000K white tends to be the crowd favorite. It looks crisp and modern and gives you strong contrast on the road. For fog lights, a lot of drivers lean toward 3000K yellow instead, since it's easier on the eyes when the weather turns nasty.

Really, the right color comes down to the job: low beams versus fog lights.

Sometimes. On vehicles with sensitive electrical systems, certain H11 LEDs need CANbus support or a decoder to stay flicker-free. Skip that compatibility, and you might run into flickering, a bulb-out warning on the dash, or lights cutting in and out.

If you notice any of that after an LED upgrade, switching to CANbus-ready H11 bulbs usually sorts it out, or just reach out to Underground Lighting for fitment help before you buy.

No, and this one trips people up. H11 and H11B use different connector styles, so they can't replace each other. If your vehicle calls for H11B, don't force in a standard H11 unless the product specifically says it's designed for that application. When in doubt, match the exact bulb type listed for your car.

H11 LEDs are the simpler upgrade, plug-and-play, instant brightness, and lower power draw. H11 HIDs use xenon lighting and need a compatible HID ballast or conversion kit to run.

So if you're coming from factory halogen H11S, LED is usually the easiest path. If you're already running or building an HID setup, then an H11 HID kit or replacement HID bulbs is what you're after.

Yes, always do both sides. Replacing them as a pair keeps the brightness, color, and beam pattern consistent across the front of your vehicle, so one side doesn't end up noticeably different from the other. This matters most when you're jumping from halogen to LED, or switching from white headlight bulbs to yellow fog lights.

Start with the basics: your vehicle's year, make, model, current bulb number, and the lighting position you're filling. Remember that H11 can show up as a low beam, a fog light, or another front position depending on the car.

Still not sure? Send Underground Lighting your vehicle details and let them know whether you're looking for an H11 headlight bulb, fog light bulb, LED bulb, or HID kit, and they'll point you to the right fit.
