My left blinker quit blinking so I pulled the front bulb and it had black oily stuff all over it. Help. What’s wrong with my car.

  1. If it was just from the connection part of the bulb then this is normal. The oily stuff is dielectric grease that:
    – Protects electrical connections and wiring from salt, dirt and corrosion
    – Prevents voltage leaks around any electrical connection
    – Extends the life of bulb sockets
