Perhaps due to all the years of vibration.

So I just pressed the lines back into plastic assembly and the bulb was tight in its socket and working again.

I noticed an extra un-used light bulb socket so I put the new bulb in there. None of the light settings or brakes seem to use this socket when I tested it so I put the new bulb in it so I could find the spare bulb when needed.

Anyone know what the extra bulb socket is for?

That happened to my tail light too
I finally used a bit of JB weld to permanently fix it
