What are the bulb models for the entire 9th-generation Civic?
4 Answers
The 9th-generation Civic has different bulb models for different functions. Here are the details: Civic bulb models: The low beam of the 9th-generation Civic is model D4SH11, the high beam is model 9005 (HB3), the fog light is model H11, the reverse light is model P21W, and the brake light is model P215W. Civic overview: The dimensions of the 9th-generation Civic are 4535mm in length, 1755mm in width, and 1450mm in height, with a wheelbase of 2670mm. The six models of the 9th-generation Civic include four 1.8L models and two 2.0L models. The 1.8L models are the EXi MT Comfort Manual, EXi AT Comfort Automatic, VTi AT Luxury Automatic, and VTi AT NAVI Luxury Automatic Navigation Edition.
I drive this generation of car often, so I know a bit about the bulbs. The ninth-gen Civic uses a common combination of bulb types: the headlights are H4 halogen bulbs with separate high and low beams; the tail lights and brake lights use 1157 dual-filament bulbs; the turn signals, both front and rear, are 1156 single-filament; the reverse lights are 921; the license plate lights are 168; and there are some small interior lights, like the dome light which uses T10 wedge bulbs. Don’t underestimate these small numbers—they’re absolutely essential for driving. If a bulb burns out and isn’t replaced, driving at night on the highway without proper lighting can be extremely dangerous. I remember once when my rear turn signal went out, I went to replace it but found the wrong bulb type was installed, causing it to flash abnormally—it’s always best to stick with the factory-matched bulbs. Owners should regularly check their bulbs, especially in older cars where the sockets can oxidize and affect contact. Also, while different trims like the LX or EX mostly use the same bulb types, some aftermarket or modified lights might differ, so it’s best to double-check the manual or confirm with the shop using the VIN code just in case.
When I first got my driver's license, I bought this generation of car, so I was curious about what bulbs it used. After asking friends and checking materials, I found that the ninth-generation Civic commonly uses H4 for headlights, 1157 for brake taillights, and 1156 for turn signals. At the rear, there are also 921 reverse lights and 168 license plate lights, while interior lights like the glove box use T10 bulbs. It's not just about the model numbers; the key is not to make mistakes during replacement. For example, the 1157 bulb has two filament positions, and inserting it backward can cause issues. Once, I replaced a taillight with an aftermarket 1157, but the brightness was so poor that I had a minor accident at night due to poor visibility. I recommend beginners learn how to identify faulty bulbs: use a phone to photograph the socket for the model number or unscrew the cover to check the original label. Additionally, bulbs in this generation typically last about two years. Opting for LEDs when replacing them can save energy and provide brighter light. Always check the light clusters after parking to ensure even illumination without dark spots.
As a car enthusiast who loves tinkering with vehicles, I've personally replaced the entire set of bulbs on my ninth-generation Civic. The headlights use H4 halogen bulbs, while the turn signals (front and rear) are 1156, and the brake/tail lights are 1157 with that standard dual-filament structure. The reverse lights use 921, license plate lights are 168, and the interior dome light is T10. Replacement is super simple: for example, with the tail lights, just disconnect the power cable, unscrew the base, swap in the same model, and plug it back in. But be careful not to touch the glass part of the bulb—oil from your hands can cut its lifespan in half. Also, when bulbs age, their light turns yellow and dims; for safety reasons, replace them then. I recommend choosing durable brands like Philips or Osram—don't cheap out on no-name brands that burn out easily. The ninth-gen model has great bulb compatibility, even the small engine bay lights are similar. Regular headlight maintenance is key, like cleaning dust, preventing water ingress, and avoiding short circuits.
