Introduction
This manual provides essential information for the safe and effective use of your AHLTD Car DRL LED Bulbs. Please read this manual thoroughly before installation and operation.
Safety Information
- Ensure the vehicle's power is off before attempting installation or removal of bulbs.
- Handle LED bulbs by their base to avoid touching the LED chips directly.
- Wear appropriate safety gear, such as gloves, during installation.
- Do not look directly into the illuminated LED bulb for extended periods, as it may cause eye strain.
- Keep out of reach of children.
Package Contents
Depending on your purchase, your package will contain 1, 2, 4, or 10 AHLTD 5630 33SMD LED bulbs.

- 1156 (BA15S): Single Contact Bayonet, 15mm base diameter, 50mm total length.
- 1157 (BAY15D): Dual Contact Bayonet, 15mm base diameter, 50mm total length.
- 7443 (W21/5W T20): Wedge base, 16mm base width, 61mm total length.
- 3157 (P27/7W T25): Wedge base, 16mm base width, 60mm total length.
Installation Steps
- Ensure your vehicle's ignition is off and the parking brake is engaged.
- Locate the existing bulb you wish to replace. Consult your vehicle's owner's manual for specific access instructions (e.g., removing tail light assembly, accessing from trunk).
- Carefully remove the old bulb by twisting or pulling it out of its socket.
- Insert the new AHLTD LED bulb into the socket. Ensure it is seated firmly.
- Test the light function before reassembling any removed vehicle components.
- If the LED bulb does not light up, remove it, rotate it 180 degrees, and reinsert it (LEDs are polarity sensitive).
- Reassemble any vehicle components removed during the installation process.

Operating Instructions
AHLTD LED bulbs are designed for various automotive lighting applications, including:
- Daytime Running Lights (DRL): Provides enhanced visibility during daylight hours.
- Tail/Brake Lights: Brighter illumination for rear visibility and braking indication.
- Turn Signal Lights: Clear and instant signaling for turns and lane changes.
- Reverse Lights: Improved visibility when backing up.
- Interior Lighting, Parking Lights, License Plate Lights: General illumination.

Maintenance
AHLTD LED bulbs are designed for long-lasting performance and require minimal maintenance.
- Cleaning: If necessary, gently wipe the bulb's lens with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Inspection: Periodically check the bulbs for proper function. If a bulb flickers or fails, refer to the troubleshooting section.
- Storage: If storing spare bulbs, keep them in their original packaging in a cool, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | Incorrect polarity (for DC circuits); loose connection; faulty bulb. | Remove bulb, rotate 180 degrees, and reinsert. Ensure bulb is fully seated. Test with another known working bulb if available. |
| Bulb flickers or flashes rapidly. | Canbus error (vehicle's computer detects lower power draw); loose connection. | For turn signals, a load resistor may be required (not included). Ensure connections are secure. |
| Bulb is dim. | Low voltage; incorrect bulb type for application. | Verify vehicle's electrical system is providing correct voltage (12V). Ensure the correct bulb type is used for the specific light function. |
User Tips
- When replacing turn signal bulbs with LEDs, some vehicles may experience "hyper-flashing" (rapid blinking). This is due to the vehicle's system detecting a lower current draw. Installing a load resistor (available separately) can resolve this issue.
- Always double-check your vehicle's original bulb type and size before purchasing to ensure compatibility.
- For reverse lights, the bright white LEDs significantly improve visibility when backing up at night.
