Using a multimeter, what resistances would I expect to get from a
working H4 car headlight bulb?

Thank you for any info.

If this is a "normal" halogen bulb like this

then no resistance would mean it is dead.

I think the pinouts are, looking at the bottom of the bulb with a terminal
on the left, right and top

Left terminal is common
Top terminal is low beam
Right terminal is high beam

So you need to measure between the left pin and the top, then the left and
the right.
