If the schematic is correct, then all the LEDs are in parallel, so shorting the taillight would mean shorting all the LEDs, and there should be no output at all.
Twinquad is right. I tried it, albeit accidentally (wire was pinched); the whole thing was dead.

1000uF, okay; but 63V? 6.3 seems to be a common capacitor rating, but I can't find any rated for 63. My actual voltage is in the range 12V- 15V; shouldn't I want a capacitor rated, I don't know, 16V? Where do I get it?

Yes, I'm reading pretty much the whole site... but some of it is beyond my comprehension.
