What headlight bulb do I need for a 2003 Honda Accord?

For a 2003 Honda Accord, the most common setup in U.S. models is a separate low-beam bulb (typically H11) and a high-beam bulb (typically 9005). However, exact bulb sizes can vary by trim and country, so you should confirm for your specific car before purchasing.

Overview of the 2003 Accord headlight configurations

The 2003 Accord is part of the seventh generation (2003–2007) and was offered in several trims (LX, EX, and V6). Headlight assemblies and bulb requirements can differ between reflector versus projector-style housings, and between markets (U.S., Europe, etc.).

Common bulb configurations

These are the configurations you’re most likely to encounter on a 2003 Accord. Use this as a starting point, then verify on your vehicle.

• Low beam: H11; High beam: 9005. This is the most common setup for U.S.-market seventh-generation Accords with separate low/high beams.


• Low beam: 9006; High beam: 9005. Some market/trim variants used 9006 for low beams.


• Dual-beam H4 (HB2) bulb in rare export models or earlier configurations, where a single bulb handles both high and low beams.

Variations exist, so check your manual or the bulb you currently have to ensure accuracy.

How to confirm the exact bulb for your car

Follow these steps to confirm the precise bulb type before purchasing replacements.

• Check the owner’s manual or the service manual’s headlight section for the bulb specification by trim and region.


• Inspect the bulb currently installed to read the markings on the base (often the numbers indicate the bulb type such as H11, 9005, or H4).


• Use a VIN-based parts diagram or the retailer’s database to confirm the exact bulb size for your specific trim and market.


• Purchase from a reputable brand and ensure the wattage matches your vehicle’s requirements to avoid electrical or performance issues.

Following these steps will help you buy the correct replacement bulb the first time and prevent damage from using an incompatible size or wattage.

Summary

In most 2003 Honda Accords, the standard setup is a separate low-beam bulb (often H11) and a high-beam bulb (typically 9005), with some trims or regional models using 9006 for low beams or H4 for dual-beam units. Always verify the exact bulb type for your specific car by checking the manual, inspecting the current bulb, or using a VIN-based parts lookup. If you share your trim and market, I can narrow down the precise bulb sizes for your vehicle.
