How to dim led headlights. 0 10v signals work by sending a separate 10v signal to the pwmtriac dimmer module and then using a resistive dimmer to reduce the voltage on the 10v signal. The quick fix cut a small piece of transparent tape and place it over the status light. This is a variable resistor that easily attaches to the dimming wires for a cost effective solution.
Headlight electrical connector step 2 release the electrical connector from headlight lens. Clean it as described in the photo. Step 1 access the rear of the headlight lens and locate the electrical connector.
Another possibility is that as headlight filaments age they deposit a graybrown film on the inside of the bulb see photo. Draw over the tape with a black permanent marker. But most dim headlights are caused by a corroded ground wire.
If that doesnt diffuse the light enough for your needs try painting over it with a couple coats of black fingernail. The current standard is 0 10v.
