The 1998 Honda Civic uses separate bulbs for low and high beams: 9006 for the low beams and 9005 for the high beams.
In the 1998 Civic, part of the EK generation, headlights are not a single H4 dual-beam unit. Each function has its own bulb, so when replacing bulbs you’ll need to select the correct size for each beam. Below is a concise guide to the common configuration and what to look for when purchasing replacements for this model year.
Bulb types for the 1998 Honda Civic (EK generation)
Low beam bulbs
The low beams on most 1998 Civics use a 9006 bulb (also known as HB4). This is the standard, single-filament bulb used for the low-beam function in the headlight housing.
- 9006 (HB4) – standard low-beam bulb
- 9006 variants such as high-output or LED replacements exist, but compatibility with the housing is essential
Concluding: When replacing the low beams, select a 9006 bulb that fits your Civic’s headlight housing and confirm any vehicle-specific notes in the owner's manual or a reliable parts diagram.
High beam bulbs
The high beams for the 1998 Civic use a 9005 bulb (HB3). This is a separate, dual-filament style bulb used for the high-beam function in the same headlight assembly.
- 9005 (HB3) – standard high-beam bulb
Concluding: For the high beams, choose a 9005 bulb and ensure it is compatible with your headlight housing and any ballast or wiring if you’re upgrading or modifying the setup.
Practical tips for replacement
Always verify the exact bulb size by consulting the owner's manual, the service manual, or the headlight diagram inside the service panel of the car. If you’re unsure, remove the bulb and check the stamped size on the base, or confirm with a trusted parts retailer using your VIN or trim level.
When upgrading or replacing, consider factors such as beam pattern, color temperature, and power draw. If you choose aftermarket or LED options, ensure proper fitment and alignment to avoid glare or misalignment.
Summary
For a 1998 Honda Civic (EK generation), the low-beam bulb is typically 9006 and the high-beam bulb is 9005. Always double-check with your owner’s manual or a reliable parts diagram to confirm the exact specs for your specific trim and headlight housing before purchasing replacements.
