Can you use 12 volt DC to light grain of wheat or grain of rice bulbs. They were originally purchased from micro mark several years ago.

Totally dependent upon the specific bulb model.
Unless they've changed grain of wheat bulbs to LED, all the grain of wheat bulbs I have (probably 20+ years old) are incandescent. If yours are incandescent, they will work on either AC or DC. It's just a matter of determining the right voltage to supply them with. You can do this by connecting one of them to a variable power supply and slowly raising the voltage until the brightness is right. If the voltage goes too high, it will burn out the filament.
If they're LED's then that's a different matter.
These are incandescent bulbs. I know they will work on 12 volt AC . I would like to light them with 12 volt DC.
You could try one by briefly (less than a second) touching the leads to the 12VDC supply terminals. If it seems really bright, then you'd need to lower the voltage. Lots of options for that.
If it seems like a good brightness, then all is well.
For your purposes 12volts AC is the same as 12 volts DC. In fact incandescent bulbs will last significantly longer on DC opposed to running on the same voltage AC.

If you know they are 12 v they will work on either AC or DC. 1.5v was also a common voltage for GOW and grain of rice bulbs.

Thank you
