If you’ve ever wandered into an auto parts store or browsed online for replacement LED bulbs, you’ve probably come across the familiar H11 vs H11B models. But wait—H11? H11B? They sound like siblings, but are they? And if they are, why does it feel like one is the more “exclusive” family member?
Well, buckle up because we’re about to break it down for you. The H11 vs H11B LED bulbs may look alike, but they actually have some key differences that can make your headlight shopping experience a lot trickier than it needs to be. Let’s dive into the details.

H11 LED Bulb
The H11 is the most common, everyday kind of bulb. It’s what your car probably came with when you bought it, and it’s the reliable workhorse of the automotive lighting world. It’s the bread and butter of low-beam headlights, fog lights, and sometimes DRLs (Daytime Running Lights). You walk into any auto parts store, and there’s a good chance you’ll find at least one shelf full of H11 bulbs
H11B LED Bulb
Enter the H11B—H11’s seem likely to be the same. The H11B looks just like the H11. In fact, you could easily mistake them for twins. But are they? Oh no. Oh, no no no. They’re not twins, they’re more like… complicated cousins with subtle differences that only reveal themselves after hours of Googling, deep-dive forums.
On the other hand, the H11B LED bulb is more specific in its fitment. The “B” in H11B isn’t just a random letter. It signals that this bulb is tailored for a narrower selection of vehicles, often those with unique electrical or physical space constraints. The H11B is typically used in specific car models and sometimes in older vehicles or those with stricter electrical specifications.
For example, certain European or Japanese cars might use the H11B as a stock bulb because of the particular way the electrical system is designed. If you have an H11B socket in your vehicle, an H11 bulb may not fit, and vice versa.
Differences Between H11 vs H11B
The main difference between the H11 and H11B bulb models lies in their base connectors. The H11 bulb features a standard base connector, while the H11B bulb has a unique connector base that is not interchangeable with the H11 bulb. It is crucial to verify the correct bulb type for your vehicle to avoid compatibility issues. The H11 bulb features a standard single-prong base, while the H11B bulb has a different base with slightly different dimensions.
