Here's a preliminary evaluation of
the lighting mods, based on a short night
run.

Headlamps
Were: standard
sealed beam on factory circuit
Now: Lucas H4 Halogen on relay circuit
Verdict:
previously described as "dim & yellow", now bright white. Massive
improvement.
Taillamps, brake lights, rear turn signals
Were: standard bulbs
Now: Moss red
LEDs
Verdict: 2X, possibly 3X brighter

Front turn signals (white on my '66 B)
Were: standard bulbs
Now: Moss white LEDs
Verdict: insanely brighter, like
flashing mini-headlights

And here's what went wrong:

Electronic flasher unit
First unit did not work out of the box.
Neither did the 2nd unit, until I
tried reversing the polarity. This was not
mentioned in any instructions. My
car was originally positive ground,
converted to negative ground, so I don't
know why this should be necessary
-- the 3-prong flasher that this was
specified as a replacement for was only
used on positive ground cars, but the
LED lamp kit can only be used on
converted cars, so this should have been
accounted for. (I'm pretty sure I
tried reversing the polarity of the first
unit, so I think it really was
DOA).

Front marker lamps
I could not use the
LEDs supplied. These replace the very small round bulbs,
but the LED is much
longer -- not only is the "bulb" section about twice as
long, but the socket
section is also longer (I have a photo comparing the
two, if you're
interested). The result is that the lens immediately contacts
the tip of the
bulb, so that as you tighten the lens-securing screws, it
depresses the bulb
in the socket against the spring, until the bulb loses
contact. If you try
this with the lights turned on, you can watch the bulb
go out as you tighten
the screws. I can't see how they ever successfully
tested this application.
Maybe they only tested it on later cars with the
slightly different lamp
location. However, this is hardly a critical
lighting application -- they are
scarcely ever used without the headlights.

Hope this is helpful.
