Today I converted my front side lights to LED. I never really liked how the single incandescent bulb only lights up half of the marker and doesn't work with the blinker. I added 3 strips of LEDs to give it a more even look and hooked it up to the PWM controller I made for my headlights. Now I can control the brightness and make them fade in and out with the blinkers. I plan on doing the rear markers next
