Thank you!

2. Please note that some vehicles (such as 2007+ Dodge, Chrysler, Jeep, GMC, BMW, Mercedes-Benz, and more) may require a set of CANBUS adapters to be installed.

To confirm if a decoder is needed, simply remove the original headlight bulb and check if the dashboard shows “BULB ERROR.” This listing does not include bulb adapters.

Question:

Q1: What are lumens?
Lumens measure the total amount of light emitted by a bulb. The higher the lumen count, the brighter the light.

Q2: Why don’t the headlights come on?
This is usually because the positive and negative poles are reversed (POLARITY SENSITIVE). For some vehicles, their polarity is reversed—you’ll need to flip the plug 180 degrees to reverse the bulb socket’s polarity, then reconnect. If the headlights won’t turn on, try this step.

Q3: Why does the headlight flicker?
Due to varying standards among car manufacturers, headlight decoder chips can only match as many manufacturers as possible. In such cases, we suggest installing a decoder or purchasing original headlight bulbs.

Q4: Why does the instrument indicate a lamp failure after the light is on?
As stated above, due to varying standards among car manufacturers, headlight decoder chips can only match as many manufacturers as possible. In such cases, we suggest installing a decoder or purchasing original headlight bulbs.
