I wanted yellow foglights, but didnt want to deal with Lamin-x. Also because I am spontaneous and have no patience waiting for things, I decided to run to Michaels (arts and craft store) and bought stained glass spray paint.
I bought this Krylon. You will notice it is orange, however if you only do like 3-4 coats it will give a nice yellow. It gets darker as you apply more coats, eventually to orange. Color accordingly.
I removed the foglights from the bumper and just sprayed them.
Here they are mounted.
Total mod time = 20 minutes.
Light output is great, however it was already yellow previously due to my DDM HID foglights (3500k)
