After looking at the links for bulbs, I have some questions.
1) Do I need single or double filament 7440's?
2) How do the LED's compare to the incandescent/halogen?
3) What's the difference between "no fade" and regular?
4) How long does amber sharpie tint last?
Thanks.

 

I just bought amber bulbs for my turn signals, it is a single filament bulb. The part number that I recall on the package was M1. I am not sure of the numerical designation but they work perfectly. Most tuner shops should have these in stock.

here is a link with more detailed information:
