What Bulb Fits My Car? Learn How to Find Yours
Headlight bulb size refers to the precise bulb fitting required for your vehicle's headlight assembly. They are not universal. headlight bulb sizes vary between vehicle make, model, and year. If the bulb size is wrong, it might not fit at all. Even if the wrong bulb size fits the headlight socket, it can lead to serious issues, such as electrical damage, overheating that may melt the housing, or improper light focus that compromises visibility.
There are a few ways to find the bulb size for your vehicle:
Check your owner's manual
The bulb fitting size specifications for your exact vehicle model should be listed in the manual. This is the most accurate method.

What Kind of Headlight Bulb Do I Need? Learn Different Headlight Bulb Types
The kind of headlight bulb you pick matters a lot for lighting up the road and being visible to others. There are three main choices: halogen, LED, and HID or Xenon. They differ in how well they work, how long they last, and how much they cost.
Halogen Bulbs
Halogen bulbs are the most commonly factory-installed option in vehicles. They generate light by heating a tungsten filament, producing a warm, yellowish glow. While halogen bulbs are an affordable choice, they consume more energy, generate significant heat, and have the shortest lifespan compared to other lighting technologies.
LED Bulbs
LED (Light-Emitting Diode) bulbs represent a significant advancement in headlight technology. They offer superior brightness, energy efficiency, and longevity, often lasting up to 50,000 hours. While the initial cost is higher than halogen bulbs, their durability and performance make them a worthwhile investment—especially for drivers who frequently travel in low-light or off-road conditions.
SEALIGHT provides a range of LED headlight bulbs in various sizes to fit most vehicles. If you're looking for the brightest LED option, the SEALIGHT S7S is an excellent choice.

HID/Xenon Bulbs
HID (High-Intensity Discharge) bulbs utilize an electric arc to excite xenon gas, producing a powerful bluish-white light that is three times brighter than halogen bulbs. They also have a significantly longer lifespan but require specialized housings and ballasts for proper operation. HID headlights are common in luxury vehicles due to their extreme brightness and efficiency.
If your vehicle is equipped with HID headlight bulb, you can either replace them with new HID bulbs or upgrade to LED headlights that fit HID sockets. SEALIGHT offers high-quality solutions for both:

Best HID to LED Upgrade: SEALIGHT SD1 Series LED Bulbs
What to Consider When Shopping for LED Headlight Bulbs
We've covered how to determine the right bulb size for your vehicle and the different types of car bulbs available. If you're planning to upgrade from stock halogen bulbs to high-performance LED headlights, it’s important to know what to look for.
Here are the essential factors to consider:
Brightness: LED brightness is measured in lumens (lm), the higher, the brighter. If you often travel offroad and are looking for a LED upgrade, this guide will help you choose the brightest LED headlight bulbs. Proper adjustment ensures maximum visibility without blinding other drivers.
Beam Pattern: Beam pattern refers to the width, height, and intensity of the light beam. You will want an even, more dispersed beam for visibility and safety. If you are upgrading from halogen to LED, it's important to look for LED bulbs with focused beams without causing glare.
Cooling System: LED bulbs generate less heat than halogen or HID lights, but they still require cooling. Some use fanless heat sinks for reliability, while high-performance LEDs integrate cooling fans.
Installation: Most halogens install easily in place of your original bulbs. However, LEDs sometimes require additional components and wiring to function properly. Here's a guide for choosing the right plug-and-play LED headlight bulbs.
CANbus Compatibility: Vehicles with a CANbus system need CANbus-compatible LEDs to prevent dashboard errors and flickering. These bulbs simulate the electrical load of halogen bulbs. If your vehicle lacks CANbus, these bulbs will still work.
