How to Change Honda Accord Headlights | Bulb Swap Guide

Changing a Honda Accord headlight requires accessing the bulb from the engine bay, removing the old bulb by rotating its locking tab, and installing a new one in reverse; the exact steps vary by model year from 2003 through 2022.

A dim or burned-out headlight on your Honda Accord doesn’t mean an expensive shop visit. Most DIYers can swap a bulb in 15 to 30 minutes once they know where to reach and what size they need. The catch: the access method changes significantly between generations, and one wrong twist or a fingerprint on the glass can send you back to the parts store. Below is the model-year breakdown and the exact procedure for each, so you hit the right bulb the first time.

What Bulb Size Does My Honda Accord Use?

The bulb size and the access route both depend on your Accord’s model year. The table below maps the low beam and high beam sizes, plus the major step that changes between generations.

Step-by-Step Replacement by Generation

Each generation has one or two tricks that save you time. Start with your model year below; if your garage is tight on the older models, you can find a tested list of compatible replacements in our 08 Honda Accord headlight roundup.

2018–2022 Honda Accord (Low Beam)

The low beam is the easier of the two. Reach behind the headlight assembly from inside the engine bay — no tools needed for the bulb itself. Press the tab on the power plug and pull the connector off. Plug the connector back in until it clicks, and you’re set.

2018–2022 Honda Accord (High Beam)

The high beam is hidden behind a reservoir on the driver side. Push the latch on the connector, twist the light toward the driver’s side tire, and pull it out. To get your hand in, slide the coolant overflow reservoir notch back or remove the windshield fluid filler neck snap-in retainer — that inch of extra clearance makes the difference. Push the new 9005 bulb into the receiver, align its locking nut with the three notches, turn toward the passenger side to lock, and reconnect the power cable. You’ll know it’s seated when the nut clicks into place.

2008–2012 Honda Accord

This generation requires removing the upper grille cover. Pop out the centers of the eight push clips on the radiator cover and pull the cover off. On either side, pry the inner fender liner retainer clips back with a flat-head screwdriver and pull the liner toward you. Pinch the top of the white block to release the connector from the old bulb, install the new 9006/9005 halogen carefully without touching the glass, and reassemble in reverse.

2003–2007 Honda Accord

The driver-side bulb on the older models is blocked by the battery. Disconnect the positive cable first, unbolt the battery hold-down, and lift the battery out to clear room. Pinch the tab on the connector and pull it back, then twist the bulb left or right to release it. Insert the new bulb, twist it straight, and plug the connector in until you feel it click. Always disconnect the battery before removal to avoid a short against the body frame.

Common Mistakes That Kill a New Bulb

Two errors cause the most repeat failures. First, never touch the glass of a halogen bulb with bare fingers — the oils create hot spots that crack the bulb within weeks. Handle with latex gloves or a clean cloth. Second, rotate the bulb in the correct direction for your side; on the 2008–2012 model, the driver and passenger sides rotate opposite ways, and forcing the wrong direction can snap the locking tab. After the swap, verify the beam alignment: If you’re upgrading to LEDs, confirm the operating voltage (9–13V) matches your Accord’s circuit and that the bulb has a sharp cut-off line to keep the beam pattern legal.
