Ya, we'll see. My other set of bulbs will be here tomorrow. I forgot to ask.. did you check to make sure your new bulbs worked with brake light? I also seen some guys were having issues with led bulbs working only running lights but when brake was applied they didn't get any brighter

 

Yep, they work.

 

Ok good. They definitely look brighter. I just might have to order a pair for the 570 and put the other ones in the 500 lol.

 

For future reference, LED means Light Emitting Diode, and diodes work like a one-way valve. Basically, electricity flows one way with barely any resistance, and the other way the resistance is so high that it blocks the flow of electricity. That's an accurate enough description to understand why flipping the polarity works sometimes.
