To troubleshoot and fix a LED light flickering issue when connected to a dimmer switch, you can try the following steps: Check if the dimmer switch is compatible with LED lights. Some dimmer switches are not designed to work with LED bulbs and can cause flickering. Make sure the LED bulb is compatible with the dimmer switch. Not all LED bulbs are dimmable, so using a non-dimmable bulb with a dimmer switch can cause flickering. Replace the dimmer switch with one that is specifically designed for use with LED lights. This can help eliminate flickering issues. If the flickering persists, consider installing a load resistor or a bypass device to stabilize the current flow and prevent flickering. By following these steps, you should be able to troubleshoot and fix the LED light flickering issue when connected to a dimmer switch.

What are the headlights doing? Is the bulb burned out? Are the lights not coming on at all? Are they misaligned?
pop the hood and look beside your headlights on the inner side of them, there should be a a little round cap type thing with an arrow on it. remove this cap and turn the dial, this is the manual way to raise and lower the headlights
