2. Safety Information
- Always ensure the power supply is disconnected before installing or replacing bulbs to prevent electrical shock.
- These bulbs are designed for 6V DC applications. Using them with higher voltage or AC power may damage the bulbs and pose a safety risk.
- Observe correct polarity during installation. The bottom contact of the E10 bulb is positive (+), and the side contact is negative (-). Incorrect connection will prevent the bulb from lighting up.
- Do not attempt to disassemble or modify the bulbs.
- Keep out of reach of children.
3. Installation
The SQXBK E10 LED bulbs feature a standard E10 screw base, making them compatible with fixtures designed for this base type.
- Ensure the device or circuit is powered off and disconnected from its power source.
- Carefully screw the E10 LED bulb into the compatible E10 socket. Ensure it is securely seated but do not overtighten.
- Important Polarity Note: These are DC bulbs. The bottom contact of the bulb is the positive (+) terminal, and the threaded side is the negative (-) terminal. Ensure your fixture provides power with this polarity. If the bulb does not light, verify the polarity of your power source or try reversing the connection if possible (though E10 bases are typically fixed polarity).

4. Operation
Once properly installed in a compatible 6V DC E10 socket, the bulb will illuminate when power is supplied to the circuit. These bulbs provide instant full brightness without warm-up time.
5. Maintenance
- These LED bulbs are designed for a long lifespan (over 50,000 hours) and require minimal maintenance.
- To clean the bulb, ensure the power is off and the bulb is cool. Gently wipe with a soft, dry cloth. Do not use liquid cleaners.
- Regularly check the socket and wiring for any signs of wear or damage.
