At the behest of my wife, who has some concern about me bombing 
around in an LBC, mixing it up with SUVs on the freeway, I decided to 
put a little money into safety stuff on my '64 B.

The most obvious one was to install a fuel pump rollover switch.  I 
bought the one that Moss sells, and thought a lot about where to 
mount it on the car to prevent it from shutting off unnecessarily, 
and to be easy to reset.  I finally decided on the firewall, 
passenger side, under the dash, toward the centerline.  It is a 
fairly rigid panel, within reach of the driver if it trips off on a 
pothole or speed bump.  Since the rear suspension is stiffer / 
jouncier than the front; putting it in the trunk seemed like an 
invitation to false tripping.

The wiring path was pretty straight-forward.  I ran a couple of wires 
from the switch along the harness through the firewall to the fuse 
block.  I pulled off the white fuel pump wire (the one that shuts off 
the pump that isn't the ignition-fed power wire) and put in some 
insulated spade connectors so as not to cut off the existing harness 
connectors.  If the thing fails or I am driving the Baja 1000, I can 
bypass the switch / go back to the old wiring.   Did some extensive 
test driving over neighborhood speed bumps to confirm it wouldn't 
trip in normal driving.  This could be a problem on a carburated car, 
as it doesn't really stop until the fuel bowl is empty, sometime 
after the switch trips.

This switch can also serve as an anti-theft device--whack it sharply, 
and it shuts off 'til you reset it...

The second thing I did was change the headlights.  They had been 
sealed beam halogens, but were pretty weak/bad pattern.  At night 
they were pretty anemic--even in a B, it was possible to drive 
"faster than you can see."  I'm still running a generator, and don't 
plan to upgrade to an alternator soon, and didn't want to upgrade to 
something that would burn up wiring, like jumbo driving lights. 
(yeh, I could install a relay some day...) I rarely drive where there 
is no on-coming traffic, so that doesn't help, anyway.  The nice 
thing with H4s is that you can select the wattage of the lamp 
(commonly available at auto part stores for bikes)--not having a 
relay, I went for a lower wattage.  I could put in driving lights, 
but if they are legally installed, they need to be on a relay with 
the high beams.

I got a couple of used H4 type halogen lamps (Carrello?).  I had gone 
this route on my Alfa GTV-6, and it made a great difference, not just 
in brightness, but in pattern.  I know they are probably not legal in 
Calif., but they are safe.   The only downside I've seen is that if 
you need to have them aimed by a state repair station, you need to 
put back the sealed beams, since they have the three DOT bosses that 
the alignment tool needs for location.
