Do headlights and fog lights use the same bulb?
No, headlights and fog lights typically use different types of bulbs. Headlights and fog lights serve distinct purposes and have different design requirements, leading to the use of distinct bulb technologies.
Headlights vs. Fog Lights
Headlights are the primary forward-facing lights on a vehicle, designed to illuminate the road ahead and provide visibility for the driver. They are typically larger and more powerful than fog lights. Fog lights, on the other hand, are auxiliary lights that are mounted lower on the vehicle, often near the bumper. Fog lights are designed to provide additional illumination in poor weather conditions, such as fog, rain, or snow, where the main headlights may not be as effective.
Bulb Types
The bulbs used in headlights and fog lights differ in several ways:
- Headlight Bulbs: Headlights typically use halogen, xenon (HID), or LED bulbs. These bulbs are designed to provide a broad, powerful beam of light to illuminate the road ahead.
- Fog Light Bulbs: Fog lights often use halogen or LED bulbs. These bulbs are designed to produce a more focused, lower-intensity beam of light that can penetrate through fog, rain, or snow more effectively.
The different bulb types and beam patterns of headlights and fog lights serve their respective purposes, ensuring optimal visibility and safety in various driving conditions.
Conclusion
In summary, headlights and fog lights do not use the same type of bulb. Headlights are designed for general road illumination, while fog lights are optimized for visibility in poor weather conditions. The distinct bulb technologies and beam patterns of these two lighting systems work together to provide comprehensive lighting solutions for drivers.
Can you use headlight bulbs for fog lights?
Many headlight bulbs are also capable of providing fog light functionality. Our Interchange Guide provides a full list of general bulb sizes and interchange numbers.
Do you use regular headlights in fog?
Fog Resources
Slow down and allow extra time to reach your destination. Make your vehicle visible to others both ahead of you and behind you by using your low-beam headlights since this means your taillights will also be on. Use fog lights if you have them. Never use your high-beam lights.
Can I use my fog lights if I have a headlight out?
Function that they would serve. So if you need headlights you got to have your headlights. On if there you encounter that strong visibility.
Are fog lights separate from headlights?
While fog lights are separate from headlights, that doesn't mean they should be used separately. You should only use your fog lights in extremely low-visibility conditions, but you still need to use your low beams with them. Fog lights help you see the physical road, but they can't help you see through the fog.
Why are fog lights illegal?
Rule 236 You MUST NOT use front or rear fog lights unless visibility is seriously reduced (see Rule 226) as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.

| H16 | 1 | Japan-style - 90* base (not PSX19 or PSX24) || H8 / H9 / H11 / H16 sockets will all fit one another (check wattage) |
Do fog lights use the same bulbs as headlights?
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.
Can I use 9005 instead of H11?
A: No, 9005 and H11 bulbs are not directly interchangeable. Despite their similar L-shaped designs, 9005 and H11 bulbs have different wattages and light outputs. They will not work properly in each other's sockets.
Can I use H4 instead of H11?
All of the bulbs discussed in this post - H1, H3, H4, H7, H11, HB3, and HB4 - are in Group 1. These bulbs are primarily used as headlights due to this classification. Even though these bulbs are in the same category, they're not interchangeable.
Can H11 be used for fog lights?
H11 is a type of automotive headlight bulb. It adapts to different lighting technologies, making it a reliable choice for both fog light and low beam needs. This light has an L-shaped socket and a single, efficient filament. It has a standard voltage of 12V, and it fits most vehicles effortlessly.
