4. Installation Guide

These T10 LED bulbs are designed for plug-and-play installation. Follow these steps carefully:

**Prepare for Installation**: Before beginning, turn off the vehicle's power and remove the key from the ignition. This prevents electrical short circuits and ensures safety.
**Locate Original Bulb**: Identify the position of the original T10 bulb you wish to replace (e.g., daytime running lights, license plate lights, interior reading lights). Gently pinch the socket and twist/pull out the original bulb.
**Insert New LED Bulb**: Align the positive and negative terminals of the new KEVANLY T10 LED bulb with the socket. Insert the LED bulb fully into the socket.
**Secure and Test**: Gently shake the bulb to confirm it is securely seated. Turn on the vehicle's power (without starting the engine) to test if the light illuminates normally.
**Troubleshooting (if light fails to illuminate)**: If the light does not illuminate, remove the bulb, rotate it 180 degrees, and reinsert it. Test again. Once the light functions correctly, secure the bulb by replacing the socket cover.

5. Operating Instructions

Once installed, the T10 LED bulbs operate automatically with your vehicle's electrical system. They are designed to function as direct replacements for your original T10 bulbs, providing consistent and bright illumination when activated by your vehicle's controls (e.g., turning on parking lights, opening doors for interior lights).

6. Maintenance

KEVANLY T10 LED bulbs are designed for long-term, maintenance-free operation. To ensure their longevity and optimal performance:

**Cleaning**: If necessary, gently wipe the bulb's exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
**Inspection**: Periodically check the bulbs for any signs of damage or loose connections.
**Avoid Disassembly**: Do not attempt to disassemble the bulb, as this will void the warranty and may damage the product.

7. Troubleshooting

If you encounter issues with your T10 LED bulbs, refer to the following common troubleshooting steps:

**Light Fails to Illuminate**:

Ensure the bulb is securely seated in the socket. Gently push it in or wiggle it slightly.
If still not lit, remove the bulb, rotate it 180 degrees, and reinsert it. LEDs are polarity-sensitive, and reversing the connection often resolves this.
Verify that the vehicle's electrical system is functioning correctly. Check fuses related to the lighting circuit.

**Light Flickers**:

Check for a loose connection in the socket.
Ensure the vehicle's voltage is stable at 12V. Fluctuations can cause flickering.
If the flickering persists and the bulb is advertised as "Canbus No Error," it might indicate a rare incompatibility or a fault in the vehicle's Canbus system requiring professional diagnosis.

**Error Message on Dashboard**:

These bulbs are designed with "Canbus No Error" functionality. If an error message appears, double-check the installation and ensure the bulb is fully compatible with your specific vehicle model's Canbus system. In rare cases, some sensitive vehicle systems may still require additional load resistors (not included) to prevent error messages.

If issues persist after following these steps, contact customer support for further assistance.

8. User Tips

Based on common user experiences, here are some tips for optimal use:

**Test Before Final Assembly**: Always test the LED bulb after inserting it into the socket and before fully reassembling any vehicle components. This saves time if polarity needs to be reversed.
**Handle with Care**: While durable, LEDs are electronic components. Avoid dropping them or applying excessive force during installation.
**Color Consistency**: If purchasing multiple bulbs, ensure they are from the same batch for consistent color output, especially for aesthetic applications.
