Safety Information
- Professional Installation: Professional installation is recommended to ensure correct wiring and prevent damage to the bulbs or vehicle's electrical system.
- Voltage Compatibility: Ensure your vehicle's electrical system is DC 12V. Using incorrect voltage may damage the bulbs.
- Handling Precautions: Avoid touching the LED chips directly with bare hands. Oils and contaminants can reduce lifespan or cause burnout.
- Heat Dissipation: Ensure adequate space for heat dissipation around the bulbs. Restricted airflow can lead to overheating and premature failure.
- CANBUS Systems: For some European vehicles equipped with CANBUS systems, an additional decoder or load resistor may be required to prevent error codes or flickering. These bulbs may not function correctly in certain vehicle models (e.g., Volkswagen, Hyundai Sonata, KIA K3 and K5, some newest or European vehicles) without such modifications.
- Installation Space: Verify available installation space in your vehicle's light housing. Some vehicles may require minor modifications for proper fitment.

Installation Guide
The 1797 S25 1157 RGB LED bulbs are designed for plug-and-play installation. However, always ensure safety precautions are followed.
- Vehicle Preparation: Turn off your vehicle's ignition and ensure all lights are off. Disconnect the negative terminal of your vehicle's battery for added safety.
- Access Bulb Socket: Locate the light housing for the bulb you intend to replace (e.g., brake light, turn signal). Access the bulb socket, which may require removing a cover or panel depending on your vehicle model.
- Remove Old Bulb: Carefully twist or pull out the existing bulb from its socket.
- Insert New LED Bulb: Align the base of the 1797 S25 1157 RGB LED bulb with the socket. Insert the bulb and twist or push it firmly into place until it is securely seated. Ensure the bulb fits perfectly into the same size socket.
- Test Functionality: Reconnect the vehicle's battery. Turn on the ignition and test the newly installed LED bulbs. Verify that they light up and respond to the remote control.
- Secure Components: Once confirmed operational, reassemble any covers or panels removed during installation.
Important Note: If the bulbs do not light up or flicker upon initial installation, especially in European vehicles with CANBUS systems, it may indicate a compatibility issue. In such cases, installing a compatible decoder or load resistor (not included) may be necessary to resolve the issue. These bulbs are not compatible with certain vehicle models such as Volkswagen, Hyundai Sonata, KIA K3, and K5, or some newer European vehicles without additional modifications.
