Introduction
It's simple to think, "They look almost identical!" when you see H8 vs H11 bulbs on a shelf or on your screen. Are H8 and H11 bulbs interchangeable? Is it possible to simply exchange one for the other? NO, H8 and H11 bulbs are not exactly the same, although they share a similar base and are often interchangeable, providing a clear but important response.
Despite their familial similarity and frequent use in comparable automotive applications, H8 and H11 bulbs differ in a few important ways. Let's break down the argument between H8 and H11.

What's the confusion about?
For good reason, the similarities between H8 and H11 bulbs are frequently confused:
- Identical Connector: The three-prong electrical connector (plug) used by both is identical. This indicates that the wiring harness physically plugs into either type of bulb.
- Comparable Physical Size: They are nearly identical in terms of the glass envelope and overall shape of their bulbs.
- Halogen Technology: Although both types have LED equivalents, halogen bulbs are nearly the only form of both.
-
Applications That Overlap: Both are frequently utilized in fog lights. Much of the confusion arises from the primary area where their applications overlap. In many contemporary cars, the H11 bulb type is also the most common for low-beam headlights.
The Crucial Distinctions: The Reasons They Cannot Be Swapped
This is where H8 and H11 divide:
-
Brightness and Wattage:
- H8: Usually runs at 35 watts.
- H11: Runs at 55 watts on average.
- As a result, the H11 bulb uses more energy and emits a lot more light (about 1350 lumens) than a H8 bulb, which uses about 800 lumens. Headlights become dangerously dim when a H8 is used in place of an H11. Placing an H11 in place of a H8 runs the risk of overloading wiring or reflectors that aren't made to handle the increased heat or wattage.
-
Principal Goal of Design:
- H8: Mainly made with fog light applications in mind. Its beam pattern and lower wattage are ideal for slicing through fog without producing too much glare-back.
-
H11: Mainly intended to be a low-beam headlight bulb. It is designed to illuminate roads at night with its higher wattage and beam pattern. Its primary purpose is headlight duty, though it is also utilized in many fog lights.
In conclusion
- H8: About 35W, about 800 lumens. mainly for fog lights.
-
H11: approximately 1350 lumens, 55W. mostly for fog lights and low-beam headlights.
Although they are related, H8 and H11 bulbs are different components in the automotive lighting industry. Recognize their differences; using the right bulb guarantees safety, correct operation, and prevents damage to the lighting system in your car. If in doubt, refer to your handbook!
Useful Guidance: Selecting Between H8 and H11
Always use a bulb that is compatible with the specifications of your car. Use an online bulb lookup tool or look into your owner's manual. Brands like Auxbeam India provide dependable plug-and-play options if you're switching to LEDs, which are a popular option for brighter, cooler light:
- Adapters for dual compatibility are frequently included with Auxbeam's H8/H11 LED Kits.
- Their GX Series LEDs have integrated fans for heat dissipation and high lumens ( white light), which are essential for India's climate.
- With interchangeable bases, products such as the Auxbeam H11/H8 LED Headlight Kit resolve compatibility issues.
Note: Never force a bulb, even though Auxbeam's kits support both sockets. Verify the factory requirements for your vehicle first!
Final Word
Despite the differences between H8 vs H11 bulbs, companies like Auxbeam India use clever engineering to close the gap. Regardless of whether you drive a Mahindra Thar (H8 fogs) or a Hyundai Creta (H11 low beams), always:
- Check the type of bulb in your car.
- For longevity and brightness, go with LEDs.
- Select reputable brands that have local support.

FAQs
Q1. what's the difference between h8 and h11 bulbs
- NO, H8 and H11 bulbs are not exactly the same, although they share a similar base and are often interchangeable.
Q2. What are H8 bulbs typically used for?
- H8 bulbs are lower power (35W, ~800 lumens), designed primarily for fog lights. H11 bulbs are higher power (55W, ~1350 lumens), designed for low-beam headlights.
Q3. Can I use an H8 bulb to replace an H11 bulb?
- Replacing H11 with H8 is NOT safe – it causes dangerously dim headlights; H11 in place of H9 is incompatible due to different bases/wattage.
