The 3W bulb for the battery idiot light provides DC excitation (12V is provided to the alternator's field windings - this excites, or "jump-starts" the alternator). Without it, the alternator will not charge.

The LED on my Battery light is non-polar, just like the 74 bulbs.
Only able to find 3-4 threads from him. Non bulb related.
