Thanks Norbsa. Sounds like something to save for another application. I'm more likely to go the other route, with a relayed connection to a better (could it be WORSE??) headlamp in the not too distant future. Plus I have this brand new battery that could power Fenway Park for an evening (and is commensurately sized and weighted - maybe I should put the passenger seat back on and simply strap it in).
That's another pint I owe you (by spring, both our livers should be at very high risk). Collectible in the Boston area at your convenience.
Thanks - BrianK
