[MirandaRose]

Common types of car bulbs include: H1, H4, H7, 9005, 9006. The methods to distinguish car bulb types are: 1. Check if the headlight is a combined high/low beam unit. If it is, the bulb type is H4; 2. Open the engine hood, remove the headlight protective cover, and take out the bulb to identify it by the pins and base; 3. If the headlight has 1 pin and a flat rectangular metal base, it is H1; 4. If the headlight has 3 pins and a round metal base with 3 protruding tabs on the outer edge, it is H4; 5. If the headlight has 2 pins and a round metal base with 1 protruding tab on the outer edge, it is H7; 6. If the headlight has 2 pins and an oval socket with a longer protruding tab on the lower edge, it is H11; 7. If the headlight has 2 pins and an oval socket with a smaller protruding tab on the upper edge, it is 9005. If it has 2 smaller protruding tabs on the upper edge, it is 9006.
