Halogen bulbs, along with LED headlight bulbs and HID conversion bulbs, come in many different shapes and sizes and are identified and referenced using a part number (bulb size or bulb number).
You may already be familiar with popular bulb sizes such as H11, 9005, H7, 9003, and H13. Regardless of the technology (halogen, LED, or HID), an H11 bulb, for example, will always be the same with regard to its locking tabs and plugs.
This is similar to household battery sizes, for example. AAA batteries will always be the same size, length, etc. regardless of the brand and technology and the same logic applies to headlight and fog light auto light bulbs.
One interesting thing about automotive headlights and fog light bulbs is that many sizes are cross-compatible or equivalent. For example, H11 is equivalent to H8, H9, and the L-Shaped H16 bulb. 9005 is equivalent to HB3, H10, 9040, 9055, 9140, 9145, 9150, and 9155.
This is because there are several different original equipment manufacturers, such as Sylvania (Osram), Philips, and Hella, which use their respective part numbers to reference the same bulb.
Backed by popular demand, we've put together a complete list of all headlight and fog bulbs and their equivalent bulbs. We also dive deeper into some popular bulb sizes and conclude with some frequently asked questions. We regularly update this page and if you see anything missing, please let us know!

As explained briefly earlier in this guide, some automotive headlamps and fog light bulbs will have different bulb/part numbers but are actually the same exact bulb. The same auto lamps are produced by different OEM producers and used by many car manufacturers.
How do we determine if bulbs are equivalent? We look at 2 key aspects, the locking mechanism (tabs) of the bulb (this is how the bulb stays secured within the headlight assembly) and the wiring/plugs (this is how the bulbs connect to your factory power harness to draw power in order to light up).
For instance, 9006 bulbs are equivalent to 9012 and HB4. All three of these bulbs are exactly the same - they have the same locking tabs, wiring, and plugs.
H11 and 9005, for example, are not the same. They look the same at first glance but have different locking tabs and plugs. If you try to insert an H11 where a 9005 belongs (or vice versa), it won't fit or lock into the headlight slot and the plug will not match that of the power harness.
Although we would like things to be perfectly simple and standard across the board, they rarely are and automotive headlight bulbs are no exception.
Below, we breakdown a few bulbs that are commonly mistaken as equivalent:H11 (sometimes referred to as H11 type A) and H11B are frequently confused as being equivalent but are in fact different due to their plug and the design of their respective headlight assemblies. H11 has the plug pins nested while H11B has the pins bare. As such, an H11 will not work for an H11B headlight and vice versa.
H11 is one of the most common bulb sizes and is used for high beam, low beam, and fog lights by nearly every car manufacturer.
H11B, on the other hand, is a lot less common and can be found on Hyundais and KIAs for their low beams.
Another interesting case is that of the H16 bulb. This bulb comes in two different "styles" despite bearing the same exact name. Thankfully, due to bulb equivalencies, we are able to distinguish them.
H16 Type 1 is the original design of the bulb and is equivalent to an H11 bulb (pictured below). It is L-shaped with nested plug pins. This is the Japanese version of the bulb commonly found in Honda,Toyota, and Subaru vehicles.
H16 Type 2 is the newer version, equivalent to bulb numbers 5202, 2504, PSX24W, PS24W, 5201, and 9009. H16 Type 2 is T-shaped (as pictured below). This version of the bulb is found on American cars such as Chevy, Dodge, Ford, GMC, and Jeep.
So, if you're ever wondering which H16 you have, check if you have a Japanese or American car. Alternatively, you can pull the original bulb and compare it to the image below.
These popular fog lights have long been a very particular case. The bulbs look nearly identical yet have very subtle differences that most aftermarket manufacturers never even noticed.
As illustrated in the image below, despite having the same tab-lock mechanism and the same exact plug, it has two sets of pins that are inversed, making them non-compatible.
Some manufacturers will simply design the bulbs without the pins in order to make them compatible but you'll need some electrical tape to make sure the connection to the power source sustains.
The L-shaped H16 bulb is the same as an H11 bulb. However, the T-shaped H16 bulb is not.
No. Despite having a similar design (same L-shape, same plug design), H11 and 9005 bulbs have different bases and locking tabs, making them incompatible. Learn more about the Difference Between H11 and 9005.
No. H7 and H11 bulbs have different bases and locking tabs, making them incompatible. Learn more about the Difference Between H11 and H7.
No. Both have an L-shape design but they have different locking tabs and electrical connections. The H11 pins are closer to each other and wider apart in the 9006.
This depends on which bulb technology you are using. For example, when using halogen bulbs, using bulb equivalencies may damage your car or cause overheating within the headlight/fog light assembly due to different wattage usage and requirements.
When using LED or HID technology, the power is regulated and, therefore, bulb equivalencies cause absolutely no harm (assuming a quality LED or HID conversion kit is used with the proper power regulating accessories).
