[ A car is a hole in the road into which you pour money ]

	WOW!!! I got inundated with responses to this one, and saw a
number of postings go by as well.  Here are a few of the responses:

----------

	"I have had both the sealed and unsealed [h4] headlights.
	The h4 lights have better beam control and are therefore
	excellent fog lights on low beam.  On the other hand, moisture
	does get in and the reflectors corrode and dull."

	"The real difference between sealed-beam halogens and European
	halogens is on low beam...I had Lucas...(my car) now has Hellas
	which seem to be of a slightly better design"

	"I  have since replaced them (ordinary sealed beams) with Hella
	H4's and have noticed a great improvement in 'seeing distance'."

	"I have been able to get them (sealed-beam halogens) for about
	5 bucks each.  and, do they make a difference at night!"

	"After I spent quite a bit of money, someone turned me on to
	Cibie...they are pretty expensive for the initial setup.  They
	are also worth it"
-----------

Well, after lots of thinking and some discussions with one of the
road-rally enthusiasts around here, I went out and bought a set of Hella
H4s to replace the low/high beam lamps, and left the old sealed-beams
in the high-beam position.  The Hellas are simple 55/60 (I think) bulbs,
but WOW!!!!!! what a difference!  I just had them properly adjusted for
a few bucks when I had the car serviced (see previous posting on hissing
sounds) and they cast a beam just shy of Tipperary (quite a long ways
from Kitchener, Ontario).  I can also attest to their impressive aim:
I was cruising back from Stratford after an evening performance (before
having them aimed; they were a bit low) through some pretty dense fog;
whereas I could see where I was going, most of the other cars on the
road had dropped to about 60 km/h, and were obviously experiencing
difficulty as a result of the light from their headlamps reflecting off
the mist and back into their eyes.
	Mark me down as one of the converted...
