I was curious, so I was thinking of using a simple transformer for street illumination or other items that just have bulbs in them. You can find inexpensive DC transformers at shows, so I thought this would work. thanks

Incandescent bulbs will work on AC or DC. No reason that I know of that you can't do this.
Just be careful you don't turn the voltage up to high or you'll blow the bulbs.
If you have AC, the addition of a diode in one side of the line to the lamps will increase life a great amount. I did this to a 70 year old set of 14VAC Christmas lights where there are 8 in series for a 112 volt circuit in the days of 110VAC at the outlet, and none of them have burned out yet. A 50-100 volt diode at a couple amps should do the trick for most setups. Draw more current, then get a higher amp rated diode.
