I recently tackled this and it took a few days, but saved a ton. I worked on the headlights all week after work and total cost..........
Less that $20
After I took apart the headlights, I applied the Krylon Fusion Satin and installed the LEDs. It takes 18 total, but I purchased a couple of extra. The LEDs I purchased cost
.48 a piece and the color is around 5000k matching my LED parking lights. The LED's are 5mm with built-in resistors which made things a lot easier. They are super bright and crisp & clean. Here's a link to where I purchased them from:
5mm 12v Pre-Wired LED White Ultra Bright 15,000 mcd
I connected the LEDS to an ignition hot (+) in the fuse box by the drivers side kick panel so they are illuminated whenever the ignition is on. Looks fantastic day & night.
