We only provide a basic installation guide.
If you have extensive experience with car modifications, you should be able to complete the installation quickly and DIY it yourself. However, if you have no related experience, please think it over carefully before attempting, or seek assistance from a local car modification shop.
We are not responsible for any damage, such as spotlight short circuits, caused by incorrect installation.
Important Notice
- The wiring harness relay is not waterproof. We recommend placing it inside the engine bay, near the battery or fuse box.
- Always confirm the correct voltage before wiring. Our spotlights are 12V by default and cannot be connected to 24V trucks. Damage caused by overvoltage is not covered under warranty.
- Check the polarity carefully before connecting—do not reverse positive and negative.
- If disassembling, always disconnect the end connected to the battery first to avoid short circuits caused by improper handling.
How To Install
First, take out the wire. The black box on it is the relay—make sure the side with the wires is facing you. From left to right, you’ll see three sets of wires:
- 【ACC/输入+】ACC/Input (+): This port has a thin red wire coming out. The remote will only work once this wire is connected to the positive power source. You can connect it to the ACC so it cuts off when the ignition is off, or directly to the battery positive.
- 【输入+输出-】Input (+) and Input (–): Connect these to the positive and negative terminals of the battery.
- 【输出+输出-】Output (+) and Output (–): Connect these to the positive and negative terminals of the spotlight.
⚠️ Important: Do not connect them in reverse! “+” is positive, “–” is negative.

Once the wiring is done, start your car and test the remote switch:
- Quickly press the button on the side of the relay 8 times. When the red light next to it stops flashing, press the button 2 more times.
- Hold down button A on the remote for 2–3 seconds until the red light turns off. This means the switch mode has been successfully paired. Press A once to turn the light on, and press again to turn it off.
- Press the relay side button one more time, then hold down button B on the remote for 2–3 seconds. This pairs the flashing mode. With B, the light will flash while you hold the button, and turn off when you release it.

- If you have some experience with car modifications, you can install it yourself. Just make sure not to reverse the polarity, and always disconnect the battery’s positive terminal before removing wires from the battery—otherwise, it could cause a short circuit.
- If you don’t have much experience with car mods, I recommend asking a local car modification shop or an auto repair shop to handle the installation.
