(rare) times I wish my generator lights would give a _little_ more
Which brings me to the question: How soon before we can buy drop-in
replacement LED bulbs for existing bike headlight generator sets?
These things already exist for flashlights, for car taillights, and
for other applications for which the electrical problems are larger
(i.e. the need to regulate current by at least crude means). Most
white LEDs will do fine with the regulated 1/2 amp that's naturally
produced by typical bike generators.
There are problems with heat sinking, I suppose. And there may be
some problems with optics, since LEDs don't emit the same near-
spherical field as a filament. Some cleverness might be needed to get
the LED to direct its light in the proper direction.
But if those could be solved (or safely ignored?) it seems there's a
