[Shotimes] Re: upgrading bulbs in headlights

[Carl Prochilo]

Great note Michael.

BTW, do you have UDPs?  I believe they would also be responsible for the
lower voltage at idle if that's the way you did the test.  If you rerun
the test at say 1500 RPM, I would expect to see higher voltage to the
headlamps.
