Replacing a burnt-out light bulb in your 1998 Honda Civic might seem like a small task, but it's crucial for safety and visibility on the road. Knowing the correct bulb sizes ensures a proper fit, optimal brightness, and avoids electrical issues. This guide will provide you with all the information you need to confidently tackle this maintenance job, ensuring your Civic remains a reliable and safe ride.
Why Knowing Your Civic's Bulb Sizes is a Big Deal
Beyond simply replacing a bulb, understanding the correct specifications is important for a few key reasons. First and foremost, using the wrong bulb can lead to dimmer lighting, reducing your visibility and increasing the risk of accidents, especially at night or in poor weather conditions. Incorrect bulbs can also overload circuits, potentially damaging your car's electrical system and leading to more costly repairs down the line. Finally, using the wrong bulb might even cause it to melt the housing. So, taking the time to ensure you have the right bulb is a wise investment in your safety and your car's longevity.
Decoding the Headlight Situation: High and Low Beams
Let's start with the headlights, arguably the most important lights on your Civic. The 1998 Honda Civic uses a specific bulb type for both its high and low beams.
- Low Beam Headlight: 9006 (HB4)
- High Beam Headlight: 9005 (HB3)
It's crucial to differentiate between these two, as they are not interchangeable. The 9006 bulb is designed to provide a wider, more focused beam for normal driving conditions, while the 9005 bulb delivers a brighter, more concentrated beam for increased visibility at longer distances. When purchasing, be sure to select the correct bulb number. Many auto parts stores will also ask for your car's year, make, and model to verify the correct fit.
Turn Signals: Front, Rear, and Side Markers
Next up are the turn signals, which are essential for communicating your intentions to other drivers. The bulb sizes differ depending on the location (front, rear, or side).
- Front Turn Signal: 1157A
- Rear Turn Signal: 1156A
- Side Marker: 194
It's important to note the "A" designation (1157A and 1156A). This indicates an amber-colored bulb, which is required for turn signals in most regions. Using a clear bulb in a turn signal application could be a safety violation and reduce visibility. The side marker uses a smaller 194 bulb, which is typically clear or amber, depending on the specific trim and regional regulations.
Brake Lights and Tail Lights: Stopping Power
Brake lights and tail lights are critical for alerting drivers behind you when you're slowing down or stopping. Like the turn signals, the 1998 Civic uses a specific bulb type for these functions.
- Brake Lights: 1157
- Tail Lights: 1157
Notice that the brake lights and tail lights use the same bulb type (1157). This is a dual-filament bulb, meaning it has two separate filaments inside. One filament is used for the tail light function (illuminating when the headlights are on), and the other, brighter filament is used for the brake light function (illuminating when the brake pedal is pressed). When replacing this bulb, ensure you're getting a dual-filament bulb to maintain both tail light and brake light functionality.
Interior Lights: Dome, Map, and Trunk
Don't forget about the interior lights! These lights provide illumination inside the cabin and in the trunk, making it easier to see and find things in the dark.
- Dome Light: DE3175
- Map Light: 194
- Trunk Light: DE3175
The dome light and trunk light use the same DE3175 bulb, which is a festoon-type bulb. The map lights, located near the rearview mirror, use the smaller 194 bulb, the same as the side marker lights.
License Plate Light: Keeping it Legal
The license plate light illuminates your license plate, making it visible to law enforcement at night. This is a legal requirement, so it's important to ensure this bulb is working properly.
- License Plate Light: 168
The 168 bulb is a small wedge-base bulb that provides sufficient illumination for the license plate.

A Few Pro Tips for Bulb Replacement
- Consult Your Owner's Manual: Your owner's manual is a valuable resource that provides detailed information about your car, including bulb types and replacement procedures.
- Safety First: Before replacing any bulb, disconnect the negative terminal of your battery to prevent electrical shock.
- Wear Gloves: Wear gloves to protect your hands and prevent oil from your skin from getting on the bulb, which can shorten its lifespan.
- Test the New Bulb: After installing a new bulb, test it to ensure it's working properly before driving.
- Replace in Pairs: If one headlight bulb burns out, consider replacing both. This ensures consistent brightness and prevents the other bulb from burning out shortly after.
- Consider LED Upgrades: While the original bulb types are incandescent, you can often find LED replacements that offer brighter light, longer lifespan, and lower energy consumption. However, ensure the LED bulb is compatible with your Civic's electrical system and doesn't cause any error codes.
- Dispose of Bulbs Properly: Dispose of old bulbs responsibly. Some auto parts stores will recycle them for you.
