5. Setup and Installation
Before installation, please verify the compatibility of the bulbs with your light fixture. It is crucial to check the bulb wattage, voltage, base type, and dimensions to ensure a proper fit and optimal performance.
- Turn off Power: Locate the power switch for the fixture and turn it off. If necessary, turn off the circuit breaker to ensure no power is supplied to the fixture.
- Remove Old Bulb (if applicable): Carefully remove the existing bulb from the fixture. Allow it to cool down if it was recently in use.
- Verify Compatibility: Confirm that your fixture requires a G4 bi-pin base and operates on 12V AC/DC. Measure the available space within your fixture to ensure the GOHDLAMP G4 LED bulb (0.43"W x 1.48"H) will fit without obstruction.
- Insert New Bulb: Gently insert the two pins of the GOHDLAMP G4 LED bulb into the corresponding holes in the fixture's socket. Apply gentle, even pressure until the bulb is securely seated. Avoid bending the pins.
- Restore Power: Once the bulb is securely installed, restore power to the fixture.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | No power to fixture, incorrect installation, or defective bulb. | Check power supply. Ensure pins are fully inserted into the socket. Test with another working bulb if available. |
| Bulb flickers or buzzes. | Incompatible transformer/dimmer, loose connection, or electrical interference. | Ensure your transformer is compatible with LED loads. If using a dimmer, ensure it is LED-compatible. Check for secure connection. |
| Bulb does not fit the fixture. | Incorrect bulb size or base type for the fixture. | Verify the dimensions and base type (G4) required by your fixture against the bulb's specifications before purchase. |
| Light is not as bright as expected. | Expectations based on halogen wattage, or voltage drop in low-voltage systems. | These 3W LED bulbs are equivalent to 20-30W halogens (380 lumens). Ensure your 12V system is providing adequate voltage. |
