Something went off in my head today an dI realised I ahd never attempted to use the light / sound feature on either my Darth's TIE or regualr TIE. I popped in brand new batteries and of course nothing happened. I ahd purchased these off teh secendary amrket years ago, so who knows. The original owner probably wore them out.

It got me curious though. Is this common for the vinateg vehicles that had this feature? Does teh feature naturally deteriorate over time or is it just from overuse. Is there a way to clean it up or fix it so it works again?

Any help ont his would be appreciated.
