I had intended to do something like running another set of power lines
for the lights, and using the existing lines to control a relay, much
as has been discussed for adding brighter headlights. The electricity
part does not scare me, but I am not anxious to drill more holes for
mounting new lights - I would like to make it look like everything is
stock... So the remaining questions are:
Where do I/can I get driving lights that will be brighter and still
fit into the bumper?
Are driving lights effective (assuming there is sufficient power) or
is the money and effort better spent upgrading the headlights.

My ignorance is showing - I thought that both fog lights and driving
lights were mounted lower, but fog lights tended to disperse more
(wide beam), while driving lights were more directed (narrow beam).
given your definition - what is the difference between headlights and
driving lights? are driving lights just more lights? or are they
mounted at headlight level, but have a narrower beam for better

Maybe this is a good idea - but which ones? Is there a review
Thanks for your input.
