Help with '66 Mustang light problems?
Neither of the front turn signals will work, although the headlights and the brights are still
working perfectly. The left taillight only comes on when the left turn signal is on,
otherwise its completely dark. The right taillight is always on, but does not blink when the
right turn signal is on. Could this be a bulb issue or possibly a fuse issue? What can I do
to get this fixed?
Still have original style bulb sockets? If so check sockets for corrosion. Reinstall known good bulb and be sure to use bulb grease. This will help with conductivity issues. Check bulb sockets for power both running light and turn signal power in each socket. This should help you narrow down where the issues are.
Remember the front parking lights are supposed to switch off when the headlights are switched on. HTH. -Jim
