Quoted from zippydapinhead:Luckily it wasn't one of the hard to find ones.
Where did you get the replacement flasher inserts for your BTTF? Wouldn't mind replacing mine as they are toast also. Good thing they don't interfere with gameplay so it's not that big of a deal. Plus under those ramps you don't see them that much anyways.
Let me know though as replacing them still would be a good thing to do.
