Installation

These T10 LED bulbs feature a plug-and-play design for easy installation. Always ensure your vehicle's power is off before attempting any electrical work.

Safety First: Turn off your vehicle's engine and ensure the ignition is in the "OFF" position. If working on exterior lights, engage the parking brake.
Locate Bulb Socket: Identify the housing for the bulb you intend to replace (e.g., interior dome light, license plate light, parking light).
Access Bulb: Carefully open the light cover or access panel to reach the bulb socket.
Remove Old Bulb: Gently twist or pull out the existing T10 (W5W/194) incandescent bulb from its socket.
Insert LED Bulb: Insert the new T10 LED bulb into the socket. These bulbs are non-polarity sensitive, meaning they can be inserted in either direction.
Test Functionality: Turn on your vehicle's power and test the newly installed LED bulb. If it does not light up, remove it, rotate it 180 degrees, and reinsert it.
Secure Components: Once confirmed working, reattach the light cover or access panel.

Important Cautions:

For 12V vehicle use only.
Avoid touching the LED beads directly with bare hands to prevent damage from oils or static.
If flickering or an error code occurs (e.g., "bulb out" warning on your dashboard), it may indicate a CANBUS system incompatibility. In such cases, a CANBUS decoder (load resistor) may be required (not included).
Professional installation is recommended if you are unsure about the process.

Operation

These T10 LED bulbs are designed to provide bright and efficient illumination for various automotive applications. They offer significant advantages over traditional halogen bulbs, including energy saving and increased brightness.

Maintenance

SEWICK T10 LED bulbs are designed for long-lasting performance with minimal maintenance. Follow these guidelines to ensure optimal lifespan and functionality:

Cleaning: If the bulb surface becomes dirty, gently wipe it with a soft, dry, lint-free cloth. Avoid using abrasive cleaners or solvents, as these can damage the LED components.
Handling: When handling the bulbs, hold them by the base rather than the LED chips to prevent damage.
Environmental Conditions: While designed for automotive use, extreme temperatures or moisture can affect performance. Ensure proper sealing of light housings.

Troubleshooting

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

Problem	Possible Cause / Solution
No light from bulb	Check the electrical connection to ensure it is secure. Remove the bulb, rotate it 180 degrees, and reinsert it (though these are non-polarity, a loose connection can sometimes be resolved this way). Check the vehicle's fuse for the corresponding light circuit. Ensure the bulb is fully seated in the socket.
Dim light output	Ensure the bulb is clean and free from dirt or debris. Remove and gently clean the bulb and socket contacts. Verify the vehicle's voltage is stable at 12V.
Flickering or error code on dashboard	This often indicates a CANBUS system incompatibility. Your vehicle's computer may detect the lower power draw of the LED bulb as a "bulb out" error. A CANBUS decoder (load resistor) may be required to resolve this issue. These are typically purchased separately.

User Tips

When replacing multiple bulbs, consider replacing them all at once for consistent brightness and color.
Always double-check the bulb type required for your specific vehicle application before purchase to ensure compatibility.
For interior lights, the brighter output of LEDs can significantly improve visibility.

Warranty and Support

For any questions, concerns, or support regarding your SEWICK T10 LED bulbs, please contact the seller or manufacturer directly. Keep your purchase records handy for faster assistance.
