Wow, I never heard of it before. I was kind of wondering about that myself not long ago because my clear corner lights look ugly during the day, you can still see the amber.
Is there any special prep that you guys used? Clean the bulbs with rubbing alcohol first or apply a primer?
I am just worried that if I apply too thick of a coat, that the amber wont show when blinking. I am already tired of getting pulled over all the time for speeding, lol.
