Installation Instructions
Installation of Alla Lighting T10 Wedge LED bulbs is a straightforward plug-and-play process. Always ensure the vehicle's power is off before beginning installation to prevent electrical issues.
General Steps:
- Locate the Bulb: Identify the incandescent bulb you wish to replace. Refer to your vehicle's owner's manual for specific bulb locations.
- Remove the Cover: Carefully remove any protective covers, lens, or housing around the bulb. This may require a trim removal tool or a small screwdriver.
- Remove the Old Bulb: Gently pull the old halogen bulb straight out from its socket. Be cautious as it may be hot if recently used.
- Insert the LED Bulb: Insert the new Alla Lighting LED bulb into the socket. These bulbs are non-polarity, meaning they will work regardless of orientation. Push straight in until it is seated firmly.
- Test Functionality: Turn on the vehicle's power and test the new LED bulb to ensure it illuminates correctly.
- Replace Cover: Once confirmed working, replace any covers or housing removed in step 2.

Operation
Alla Lighting T10 Wedge LED bulbs provide instant-on, 360-degree amber yellow light output. They are designed for consistent performance within the specified voltage range of 12V-18V DC. Once installed, the bulbs will operate in conjunction with your vehicle's existing lighting system, providing enhanced visibility and a modern aesthetic.
Maintenance
These LED bulbs are designed for a long lifespan of up to 30,000 hours and require minimal maintenance. Unlike traditional halogen bulbs, they do not have filaments that can burn out, significantly reducing the need for frequent replacements. To ensure optimal light output, periodically clean the bulb and surrounding lens from any accumulated dirt or debris using a soft, dry cloth.
Troubleshooting
Bulb Does Not Light Up:
- Ensure the vehicle's power is on and the light switch is in the correct position.
- Check the connection: Ensure the LED bulb is fully and securely inserted into the socket. A loose connection can prevent illumination.
- Verify correct bulb type: Confirm that the T10 Wedge bulb is the correct type for your vehicle's specific application.
- Check vehicle fuse: Inspect the relevant fuse in your vehicle's fuse box. A blown fuse can prevent power from reaching the bulb.
Hyper Flashing (for turn signals):
- If these bulbs are used as turn signals, some vehicles may experience hyper flashing (rapid blinking) due to the lower power consumption of LED bulbs compared to incandescent ones. This can typically be resolved by installing load resistors (sold separately) or an LED-compatible flasher relay.
