There is no single universal low-beam bulb; the correct bulb depends on your vehicle’s make and model.
Most modern cars use halogen low-beam bulbs such as H11 or H7, while some older models rely on the H4 dual-beam bulb. In many newer vehicles, the low beam is an HID (Xenon) or LED module rather than a standard halogen bulb. Always check your owner's manual or the label on the headlight housing to confirm the exact bulb type for your car.
Understanding what defines a low-beam bulb
Low-beam headlights are designed to illuminate the road ahead with a downward cutoff to prevent blinding oncoming drivers. The bulb type and the housing determine the light pattern and socket compatibility. When replacing, you must match the exact type, wattage, and connector for safe operation.
Common low-beam bulb types
Below are the most widely used low-beam formats you are likely to encounter. The exact option for your car will be listed in the owner’s manual or on the headlight housing.
- Halogen H11 — a common, relatively compact bulb found in many newer models’ low beams.
- Halogen H7 — widely used in European cars and several Asian models for low beams.
- Halogen H8/H9/H16 — variations used in certain makes, often in dedicated low-beam sockets.
- H4 (also known as 9003) — a dual-beam bulb providing both low and high beams in one unit, common on older vehicles.
- Xenon/HID low-beam assemblies (D1S/D2S, D3S, etc.) — high-intensity discharge options found on many mid-to-late-2010s and newer vehicles, requiring ballast.
- LED low-beam modules — replacement LEDs or full LED headlight assemblies that may require CAN-bus adapters or specific housings.
Compatibility matters more than popularity: using the wrong bulb type can affect beam pattern, legality, and safety. When in doubt, consult the owner’s manual or a qualified technician.
Regional trends and practical tips
European and Asian markets
Many cars in Europe and parts of Asia use H7 or H4-based setups for the low beam, with a growing share of LED or HID options in higher trims.
North American market
U.S. and Canadian models commonly feature H11 or related variants in many newer vehicles, though some use H9, H8, or dual-beam configurations. Check your specific model’s manual for the correct bulb code.
The exact bulb will vary by model and year, and some new cars may use full LED arrays or replacement modules that are not easily swapped like traditional bulbs.
Summary
The low-beam bulb you need depends on your car. There is no universal "the" bulb. Common options include halogen H11, H7, H4; HID/D1S-D3S family; and LED assemblies. Always confirm with the owner's manual, the headlight housing label, or a professional to ensure safe and legal operation.

Which one is a low beam headlight?
Low beams are angled towards the road and must always be on at night or in low-light settings such as tunnels. High beams are angled upwards for extra light and should only be used in very dark areas when there is no oncoming traffic to not blind other drivers.
Which one is low beam, H11 or 9005?
H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
