Rechargeable Door Lights Installation

For rechargeable door logo lights, please watch the installation video first. After installation, test whether the light turns on/off with the car door. Use the sensor sticker only if the automatic switch does not work well.

Sensor Sticker Placement

Installation Focus

Fully charge the lights before first use. Install the light first, then open and close the door to test whether it turns on and off automatically. Only use the sensor sticker if the automatic switch does not work well.
Charging note: Please use only the charging cable included in the package. Do not use a charger over 40W.
No Wiring Rechargeable Sensor Sticker May Be Needed
Key point: Not every car needs the sensor sticker. For some cars, the rechargeable door lights automatically turn on/off with the car door. For cars with a special door sill structure, such as Porsche Cayman or Boxster, the induction signal may be weaker and the sensor sticker may be needed.

Sensor Sticker Setup Steps

Fully charge the door lights Charge both lights before first use. Red usually means charging; blue usually means fully charged. Please use only the included charging cable and do not use a charger over 40W.
Install the rechargeable door light Place the rechargeable light into the correct door position or mounting area.
Find the sensor area Open the door and identify the side of the light that reacts to the sensor sticker.
Place the sensor sticker Stick the small induction sticker on the doorsill or matching position where it aligns with the sensor area.
Test automatic on/off Open and close the door several times. If the light does not turn off correctly, adjust the sticker position.

Door Light Installation FAQs

Common questions about car door logo light installation, plug & play door lights, and rechargeable door lights.

Why does the logo appear upside down?

The left and right door logo lights may have been installed on the wrong side. Please swap the left and right lights first, then check whether the projected car logo direction is correct.

Why does the door light not turn on?

Please check whether the plug is aligned with the pins on the door light. If the pins are not aligned, the connector may not make good contact. You can gently adjust the pins on the door logo light, then connect the plug again.

Why does my rechargeable door light stay on after closing the door?

Not every car needs the sensor sticker. Please test the rechargeable door light first. If it turns on and off normally with the door, you do not need to use the sticker. If the light stays on or the induction switch is weak, place the sensor sticker on the door sill. Some cars, such as Porsche Cayman and Boxster, may need the sticker because of the special door sill structure.

How long does it take to fully charge rechargeable door lights?

Rechargeable door logo lights usually take less than 2 hours to fully charge. Charging time may vary slightly depending on the charger, cable, and remaining battery level.

Why won’t the door light fit into the original position on my 2026 Lexus RX350?

Try inserting one side first, then use the included installation tool to press the other side into place. You can watch the Lexus door light installation video for reference. If it still does not fit, please ask a professional installer for help.
