Finally got the bulbs this week and tryed them out.
It worked sort of, the Light drained the power after
about one minute or so just what I wanted.
Strange thing is only one of the bulbs lighted up the
other one did not seam to be on.
Because they where wired in series I know electricity
must have gone through both of them.
What is going on, anybody know why only one light was on?
How do I fix it.

*****************

Sounds like the two bulbs are not the same type. Are the two bulbs the same voltage and power rating? Try measuring the resistance of each with an ohmmeter. Should be the same resistance, within 10% anyway.
