Can I use a 6 volt bulb to replace a 2.5 volt bulb in a string of Christmas lights?

Maybe, maybe not.
Depends what each bulb is.
At best, you will get maybe 1/6 the light output for the same wattage rating bulb.
i.e.a 6v 2.5w bulb replacing a 2.5v 2.5w bulb will only give you around 0.4w
Chances are it will probably not light up at all.

If the bulbs are in series, then the bulb current is more important than voltage. A low current bulb would go pop since the other bulbs in the string would control the current.

How many bulbs in the string? To run off your mains you would need about 50 in series.

Any stores near you that might carry the replacement bulb you need? I think most places are going to LED's now, but a small package of replacement bulbs for the old strings used to be pretty cheap.
