cowl and rear lights

[Kenjt]

The previous owner of my 1931 deluxe roadster installed a turn signal. I noticed that right rear light does not work which I assume is just the easily replaced bulb. I thought the cowl lights would also be controlled by the turn signal but they do not light at all. They also don't light when I turn on the headlights, in either position. Could this also be because the bulbs need replacing or did the previous owner just mess up the wiring?
