This isn't right.
Putting another bulb in parallel with the first one is going to make the 
overall resistance of the circuit half of what it was,  but the bulb itself 
is still going to have the same resistance and it's still going to pass the 
same amount of current as it would have before doing this -- you will see 
that the extra current will cause the _other_ bulb to draw it's share.
Neither will light up to anywhere near reasonable brightness,  either.
Have you even actually *tried* this?  I don't think so...
