How to adjust LED lights when one side is white and the other side is yellow?

LED lights not working are usually caused by a damaged patch, resulting in the entire LED strip not lighting up or partial lighting. To further diagnose the issue, you can connect two batteries in series. After connecting them in series, touch the positive terminal of the battery to the positive terminal of the LED patch and the negative terminal to the negative terminal of the patch, testing each one individually.
I've seen many car owners encounter the issue where one side of the LED headlights appears white while the other side looks yellow, usually due to bulb aging or mismatched color temperatures. First, try manual adjustment: remove both bulbs to check for any signs of burning or color inconsistency. If the LED bulbs are adjustable in color temperature, use the switch or remote to set them to a uniform setting, such as 6000K white. If the bulbs themselves are faulty, replace them with new ones, ensuring they are the same model and brand to avoid color differences caused by batch variations. Also, inspect the headlight wiring harness connectors to ensure there's no looseness or corrosion, as this can cause unstable voltage leading to color changes. Sometimes, high-power LEDs with poor heat dissipation can also exhibit this issue—clean the lamp cover and heat sink. If you can't handle it yourself, seek professional repair. Uneven lighting severely affects nighttime driving safety, and an accident would be a greater loss, so address the problem as soon as you notice it. Regular maintenance should include checking the condition of your headlights—don't overlook minor issues.
