Setup and Installation
The SEALIGHT 194 LED bulbs are designed for a straightforward, plug-and-play installation. Please follow these steps carefully.

- Step 1: Remove the Original Bulb. Carefully remove the existing incandescent bulb from its socket. Ensure the vehicle's ignition is off and the lights are off before beginning.
- Step 2: Connect the LED Bulb. Insert the SEALIGHT LED bulb into the socket. The design is non-polarity, allowing for insertion in either direction.
- Step 3: Test the LED Bulb. Turn on your vehicle's lights to test if the LED bulb illuminates.
- Step 4: Secure the LED Bulb. Once confirmed working, secure the bulb firmly in the socket and reassemble any removed components (e.g., light housing, trim panels).
Important Note: While these bulbs are designed with non-polarity for easy installation, if the bulb does not light up upon initial insertion, remove it, flip its orientation, and reinsert it into the socket. This can resolve rare connection issues.
Operating Instructions
Once installed, the SEALIGHT 194 LED bulbs operate like your vehicle's original bulbs. Simply activate the corresponding light function (e.g., turn on your vehicle's interior lights, license plate lights, or dash lights) to illuminate the LED bulbs. No special operating procedures are required.
Maintenance
- Cleaning: If necessary, gently wipe the bulb's lens with a soft, dry cloth. Avoid using abrasive cleaners or solvents, which could damage the lens or LED chips.
- Inspection: Periodically check the bulbs for secure fitment in their sockets. Loose connections can lead to flickering or intermittent operation.
- Replacement: Due to their long lifespan, frequent replacement is not anticipated. Replace only if a bulb ceases to function.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | Loose connection or rare polarity issue. | Remove the bulb, flip its orientation, and reinsert it firmly into the socket. Ensure the vehicle's light switch is in the ON position and check the fuse for the circuit. |
| Bulb flickers. | Unstable power supply or loose connection. | Ensure the bulb is securely seated in the socket. Check vehicle's electrical system for stable voltage. If flickering persists, consult a professional mechanic. |
| Bulb is dim. | Incorrect bulb type or power issue. | Verify that the correct bulb type (194/T10/2825/W5W) is used. Check vehicle's voltage and ensure there are no other electrical issues. |
