Excelle headlight diagram Overview
The headlight reminder Buzzer Circuit in the Shanghai Excelle consists of several key components:
- Headlight switch
- Ignition switch
- Buzzer
- Headlight relay
- Battery
- Fuse
These components work together to detect when the headlights are on and the ignition is off, and sound the buzzer to remind the driver to turn off the lights. Here is a simplified diagram illustrating the basic layout:

The key elements and their functions are:
| Component | Function |
|---|---|
| Headlight Switch | 3-position switch controlling headlights (Off, Park, On) |
| Ignition Switch | Switches power from battery to vehicle electrical systems based on key position |
| Buzzer | Produces audible tone to alert driver when triggered |
| Headlight Relay | Switches power to headlight bulbs when headlight switch is On |
| 15A Fuse | Protects headlight circuit from excessive current draw |
When the headlight switch is in the On position and the ignition switch is Off, current flows through the buzzer, producing a reminder tone. The buzzer will sound until the headlights are manually switched off.
Troubleshooting Headlight Buzzer Issues
If the headlight reminder buzzer stops working in your Shanghai Excelle, there are a few common causes to investigate:
- Check the 15A fuse for the headlight circuit. If blown, replace it.
- Examine the wiring and connectors at the headlight and ignition switches for damage, corrosion or loose connections. Clean or replace as needed.
- Test the buzzer itself for proper function. It should produce a tone when 12V is applied. Replace if faulty.
- Verify the operation of the headlight relay. The contacts should click when 12V is applied to the coil. Replace if defective.
By methodically testing each component, you can isolate the root cause and make the necessary repairs to restore the headlight reminder buzzer operation.
Headlight Buzzer Disabling
Some Excelle owners may wish to disable the headlight reminder buzzer. While not recommended from a safety perspective, it is possible to disable the function with a simple wiring modification:

Locate the wire that provides power to the buzzer when the ignition is off. Cut this wire and insulate both ends with electrical tape or heat shrink tubing. Secure the wires to prevent rattling. Keep in mind that with the buzzer disabled, the headlights may be left on inadvertently, potentially leading to a dead battery.
Frequently Asked Questions
Q: What triggers the Excelle’s headlight reminder buzzer?
A: The buzzer sounds when the headlight switch is On and the ignition switch is Off, reminding the driver to turn off the headlights.
Q: How can I tell if the headlight buzzer fuse is blown?
A: Locate the 15A fuse for the headlight circuit in the Excelle’s fuse box. Visually inspect it to see if the metal wire inside is melted or separated. You can also use a Multimeter to check for continuity.
Q: Can I replace the original Excelle buzzer with a louder or softer one?
A: Yes, as long as the replacement buzzer has the same operating voltage (12V) and can handle the current in the circuit, it should be possible to substitute a different buzzer to suit your preference.
Q: Is it legal to disable the headlight reminder buzzer?
A: While there may not be a specific law requiring the buzzer, disabling it is generally not advisable from a safety standpoint. Forgetting to turn off your headlights can lead to a dead battery and potentially hazardous situations if your vehicle won’t start.
Q: How can I test the Excelle’s headlight relay?
A: Remove the relay and apply 12V to the coil terminals. You should hear a clicking sound as the contacts engage. Use a multimeter to check for continuity between the relevant pins when energized. If the relay is silent or fails the Continuity Test, it likely needs replacement.
By understanding the circuit diagram and components of the Shanghai Excelle’s not closed headlight reminder buzzer system, drivers can more effectively diagnose and repair any issues that arise. While disabling the buzzer is possible, it is generally recommended to leave this helpful safety feature intact.
