Important considerations
- Check your specific vehicle: Bulb types can differ even within the same model year depending on the trim level. The best way to be sure is to check your owner's manual or use an online bulb finder tool from a parts retailer.
- Replace bulbs in pairs: It's recommended to replace both headlight bulbs at the same time to ensure even brightness and performance.
- Avoid touching the glass: When handling new bulbs, avoid touching the glass with your bare hands. Oils from your skin can cause the bulb to overheat and fail prematurely.
Is H7 a high or low beam bulb?
Yes, H7 bulbs can be used for both high and low beams, but they are a single-filament bulb and require a separate bulb for each function. This means if your car uses H7 bulbs, it will have one H7 bulb for the low beam and another, separate H7 bulb for the high beam, as opposed to a dual-filament bulb (like an H4) that does both in a single unit.

- Single-filament design: An H7 is a single-filament bulb, meaning it only has one filament and can only perform one function: either high beam or low beam.
- Separate bulbs: To have both high and low beams, a vehicle using H7 bulbs must have two separate H7 bulbs in each headlight assembly: one for the low beam and one for the high beam.
- Vehicle-specific: While H7 bulbs are common for both functions, it's essential to check your car's owner's manual to confirm if your vehicle uses H7s for both, or if it uses a different type of bulb for one or both beams, such as a dual-filament bulb like an H4.
Is H11 the high or low beam?
An H11 bulb is typically used for low beam headlights and fog lights, while the 9005 (HB3) bulb is commonly used for the high beam. While H11 bulbs are designed for low beams, always check your vehicle's manual to confirm the correct bulb type for your specific car, as some vehicles may use them for high beams as well.
- H11: Primarily used for low beams and fog lights.
- 9005 (HB3): Typically used for high beams, providing higher brightness than H11 bulbs.
- Confirmation: It is essential to consult your car's owner's manual to ensure you have the correct bulb type for your vehicle's application.
