Front turn signal bulbs keep quit working, this appears to be a poor design on the bulb socket to headlamp housing connection, both sides have had this issue multiple times, if you remove the socket and reinstall it they start working again, there is no corrosion present. This should be investigated as it creates a serious danger to occupants as other vehicles are unaware of the vehicles intended direction.
