2. Setup and Installation
This LED bulb is designed for simple drop-in replacement. Follow these steps for installation:
- Ensure Power is Off: Before beginning installation, verify that the power to the circuit where the bulb will be installed is completely turned off to prevent electrical shock.
- Remove Existing Bulb: Carefully remove the old incandescent bulb from its socket. Allow it to cool if it has been recently in use.
- Insert LED Bulb: Align the double-contact bayonet base (Ba15D) of the Aero-Lites AL-94F LED bulb with the socket. Gently push down and twist clockwise until the bulb is securely seated.
- Test Functionality: Restore power to the circuit and test the new LED bulb to ensure it illuminates correctly.

3. Operating Instructions
The Aero-Lites AL-94F LED bulb operates on 12-14V DC power and is designed to be dimmable. Its bipolar design means it can be inserted into the socket without concern for electrical polarity.
- Voltage: The bulb is designed for 12VDC to 14VDC systems. Operating outside this range may affect performance or bulb lifespan.
- Dimmability: This LED bulb is dimmable. However, older rheostat-style dimmers, especially those designed for higher-wattage incandescent bulbs, may exhibit a limited dimming range or cause the LED to cut off abruptly at lower settings. For optimal dimming performance, a modern LED-compatible dimmer may be required.

4. Maintenance
LED bulbs generally require minimal maintenance. To ensure optimal performance and longevity:
- Cleaning: If the bulb becomes dusty, gently wipe it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Handling: Handle the bulb by its metal base whenever possible to avoid touching the LED array directly.
- Environment: Ensure the bulb is used within its specified voltage and temperature ranges. Excessive heat can reduce LED lifespan.
5. Troubleshooting
If you encounter issues with your Aero-Lites AL-94F LED bulb, consider the following:
- Bulb Does Not Light Up:
- Verify that the power to the circuit is on.
- Ensure the bulb is correctly seated in the socket. Remove and reinsert it, twisting firmly to secure.
- Check the voltage of your system to ensure it is within the 12-14VDC operating range.
- Although the bulb is bipolar, ensure there are no other polarity-sensitive components in the circuit that might be interfering.
- Limited or No Dimming Functionality:
- Older rheostat-style dimmers may not be fully compatible with low-wattage LED bulbs. They might not dim to very low light levels or may cause the bulb to turn off abruptly.
- Consider upgrading to an LED-compatible dimmer for a smoother and wider dimming range.
- In some systems, adding a small additional load (e.g., another incandescent bulb in the same circuit or a resistor) can sometimes improve dimming performance with older dimmers, as LEDs draw significantly less current. Consult a qualified electrician if attempting circuit modifications.
- Flickering:
- Flickering can sometimes occur with incompatible dimmers or unstable voltage. Check your power source and dimmer compatibility.
