Usage & Installation Guide
Compatible Applications
This bulb is a versatile replacement part suitable for various vehicle makes and models, particularly common in Japanese, American, and European cars. It is primarily used in the following lighting functions:
Backup/Reverse Lights: Provides illumination when the vehicle is in reverse gear.
Brake Lights: Signals to other drivers when the vehicle is slowing down or stopping.
Turn Signal Lights: Indicates the driver's intention to turn or change lanes.
Tail Lights: Ensures the vehicle is visible from the rear during nighttime or low-light conditions.
Installation Steps (General Guide)
Safety First: Ensure the vehicle is turned off and the keys are removed from the ignition. Allow the existing bulbs to cool down if they were recently in use.
Access the Light Housing: Open the trunk or access the back of the tail light assembly from inside the vehicle. Some models may require removing a plastic cover or unscrewing a few fasteners.
Remove the Old Bulb: Locate the bulb socket. Gently press and twist the socket counterclockwise to unlock it from the housing. Carefully pull the socket out with the old bulb attached.
Replace the Bulb: Without touching the new bulb's glass with bare hands (oils from skin can shorten its lifespan), press it firmly into the socket. Align the tabs on the bulb base with the slots in the socket and twist clockwise to lock it in place.
Test the Light: Before reassembling everything, turn on the vehicle's ignition and test the new bulb by activating the corresponding function (e.g., turn on reverse gear or step on the brake pedal).
Reassemble: If the bulb works correctly, reinsert the socket into the housing, secure it by twisting clockwise, and reattach any covers or panels that were removed.
