- Turn off the vehicle ignition.
- Unpack the lamp and inspect all accessories for any damage or missing parts.
5.2. Mounting the Lights
Use the provided tools and mounting hardware to secure the lights to your vehicle's bumper, roof rack, or grille. Ensure the lens is facing forward and unobstructed. The lights can be installed in either a reverse or forward orientation as shown in Figure 3.

5.3. Wiring
Refer to the wiring diagram in Figure 4 for correct connections. This product involves wires and should be installed by a qualified mechanic or electrician.
- Connect the red wire (positive) of the lamp to the positive terminal of the vehicle's power source.
- Connect the black wire (negative) of the lamp to the negative terminal of the vehicle's power source.
- Important: Do not connect directly to the battery without a fuse. Ensure a fuse is incorporated into the circuit.
- Connect the switch to the power source, typically to an accessory wire behind the dashboard that receives power when the ignition is on.
- Ensure all 5-pin waterproof IP68 connectors are securely fastened.
- The wiring harness includes connections for Horn and Overtake functions, which can trigger specific light behaviors (e.g., High Beam flash).

6. Operation
- Turn on the vehicle ignition.
- Turn the auxiliary switch to the "ON" position. The LED strip should illuminate instantly.
- To change modes (e.g., High/Low Beam, DRL colors, Strobe), press the switch repeatedly.
The D040-AWY model features a dimmer switch with strobe functionality, allowing for brightness adjustment (100/80/60/40%) for both low/high beam in steady and flash modes. It also supports flashing the high beam simultaneously/alternately when the high beam is on, or flashing the low beam simultaneously/alternately when the high beam is not on.
