So tonight I was driving home, I decided to roll down some windows as it was kinda stuffy. I noticed the headlights dimmed whenever I used the power windows. Now I realize that the Fiesta is running quite a bit of electrical devices, headlamps, tail lamps, instrument panel, ambient lighting, and LED lighting (irrelevant since LEDs suck up little to nothing). Thinking of a way to improve electrical flow, maybe a grounding kit would help a bit, or even an oversized battery. Ideas?
