How to judge whether the LED headlights are installed properly?

To determine whether the LED headlights are installed in place, you can refer to the following points:

Check the direction of the bulb: Make sure the LED headlights are installed vertically and the lamp body is upright. You can confirm this by observing whether the wire on the LED fan is vertically facing down.

Confirm the power connection: Check whether the power plug is firmly inserted to avoid looseness or poor contact.

Test the light: Turn on the headlights and check whether the light is on normally. If the bulb does not light up, it may be that the positive and negative poles are connected in reverse and need to be replugged.

Adjust the light pattern: Make sure the light is irradiated in the correct direction. You can adjust the adjustment knob behind the headlight to make the light form the correct light pattern on the wall.
