For the 2007 Honda Accord headlight wiring diagram, you will need to look at the diagram for the specific model and trim level of your vehicle, as the wiring may differ based on these factors.
Understanding the Symbols
Before diving into the 2007 Honda Accord headlight wiring diagram, it’s important to understand the symbols used in the diagram. Here are some common symbols you may encounter:
| Symbol | Meaning |
|---|---|
| B | Battery |
| G | Ground |

| Connector | A device used to join two or more wires together |
Reading the Diagram
The 2007 Honda Accord headlight wiring diagram is broken down into various sections, including the front turn signals, front parking lights, low beams, high beams, and so on. Each section will show you the wires connected to each component, as well as the color of the wires.
When reading the diagram, pay attention to the wire colors and whether they are solid or striped. Solid wires indicate a main wire, while striped wires indicate a secondary wire.
Front Turn Signals
The front turn signals are connected to the main wire harness with a 4-pin connector. The brown/white wire is the ground wire, while the green wire is the turn signal wire. The turn signal switch sends power to the green wire when the turn signal is activated, causing the turn signal to flash.
The front turn signals are also connected to the hazard switch. The hazard switch sends power to the turn signals through a separate circuit, which is why the turn signals will still work even when the hazard lights are on.
Front Parking Lights
The front parking lights are also connected to the main wire harness with a 4-pin connector. The brown/white wire is the ground wire, while the brown wire is the parking light wire. The parking light switch sends power to the brown wire when the parking lights are turned on, causing the parking lights to illuminate.
Low Beams
The low beams are connected to the main wire harness with a 3-pin connector. The black wire is the ground wire, while the white wire is the low beam wire. The low beam switch sends power to the white wire when the low beams are turned on, causing the low beams to illuminate.
High Beams
The high beams are also connected to the main wire harness with a 3-pin connector. The black wire is the ground wire, while the blue wire is the high beam wire. The high beam switch sends power to the blue wire when the high beams are turned on, causing the high beams to illuminate.
Frequently Asked Questions
What causes my headlights to flicker?
Headlight flickering can be caused by a variety of issues, such as a failing alternator, loose connections, or a faulty headlight switch. Consult a mechanic to diagnose and repair the issue.
Why do my headlights stay on even when the car is turned off?
