Just a bit of fun. Lower switch turns each one off as normal. The upper switch acts a blown lamp, this causes the gate on the transistor to go low thus activating the warning LED. Replace lamp by throwing  upper swich and back to normal.

Only tested at 12V, when I have more time I will try other voltages.

If you really have this kind of bulbs 1.5V/30mW why not this way http://everycircuit.com/circuit/5105700326080512
