Solve Your Circuit Question: Understanding Voltage Drop in Series Lamps

[modis15]

"3 identical lamps are connected in series to a 6 V battery. What is the voltage drop across each lamp?"

V=RI
I have no idea of how to go about this, but I'm sure I'm making it harder than it really is.

Use Kirchhoff's voltage law.
