What Are the Models of Automotive Bulbs?

Different vehicles may have different headlight bulb models. Common models include H1, H3, H4, H7, H11, etc. Below are some methods for maintaining automotive headlights: Regularly clean the lamp cover: The headlight cover should be regularly cleaned and maintained. Frequently use a soft cloth to wipe the outer surface of the lamp cover to keep it clean. Every 3 months or so, wash the headlights with soapy water, dry them, and then polish them with a polishing agent. Replace bulbs periodically: Headlight bulbs also need to be replaced regularly. After driving about 50,000 kilometers or 2 years, the brightness of the bulbs may diminish. If the brightness is indeed insufficient, it is recommended to replace them.
I often help friends with car light issues. There are quite a few types of car bulbs, mainly depending on the vehicle model and position. The most common headlight types are H4 or H7, while Toyota Corollas often use H11 halogen bulbs. For taillights, 1157 or 580 types are common. Choosing the wrong bulb type can cause the light to not work or blow a fuse. I recommend checking the vehicle manual or searching online with the model number to find the right match. I've also encountered accidents due to dim lights, so using the correct bulb type ensures safety. When replacing a new bulb, make sure the voltage is stable and doesn't exceed the factory specifications to ensure clear night-time visibility and avoid accidents. Regularly checking the bulbs is also a good habit.
I enjoy DIY car repairs and have found that bulb models must be precisely matched to function properly. For example, my SUV uses 9005-type bulbs for headlights and 7443-type for brake lights. If you're unsure about the model, check the label on the old bulb under the hood or enter your car model on an online shopping platform to find the corresponding bulb type. After replacing the bulbs, the brightness improved significantly, and it's more convenient. A reminder: wear gloves before handling, avoid touching the glass surface as stains can shorten the bulb's lifespan. LED bulbs are more energy-efficient but have stricter model requirements—always check compatibility to avoid circuit damage. Regular maintenance can prevent sudden light failures, and simple tools are all you need to get the job done.
