What are the models of car light bulbs?

[ZoeyLynn]

Car light bulb models include: h1, h4, h7, 9005, 9006. The methods to distinguish car bulb models are: 1. Check if the headlight is a combined high/low beam unit - if yes, it indicates the bulb model is h4; 2. Open the hood, remove the headlight protective cover and take out the bulb to identify by the pins and base; 3. If the headlight has 1 pin with a flat rectangular metal base, it's h1; 4. If the headlight has 3 pins with a round metal base and 3 protruding tabs on the outer edge, it's h4; 5. If the headlight has 2 pins with a round metal base and 1 protruding tab on the outer edge, it's h7; 6. If the headlight has 2 pins with an oval socket and one longer protruding tooth on the lower edge, it's h11; 7. If the headlight has 2 pins with an oval socket and one smaller protruding tooth on the upper edge, it's 9005; if there are two smaller protruding teeth on the upper edge, it's 9006.
