I have a 78 280 Original owner 83k miles 4 Speed Burgundy/Black Having a issue with the brake lights and tail lights not turning off Might be a coincidence but while driving home just before I noticed the problem I felt something underfoot. Turns out it is some kind of plug like object clear somwhat soft plastic. About a half inch in Dia. and about an inch long. Any body know if what it may be and if it is related to the lights issue Thanks for any advice
