You'd think most people would do that too. Most of my family with cars that
have DRLs and no automatic headlights are the ones that drive around at
night with just the DRLs lit up. I guess I'm like you and like to be able to
make out the stuff on the cluster. Another thing that is really hard to do
with automatic lights/DRLs is turn them on and off to show other people that
they don't have their lights on.
I do not know if you hold an engineering degree or not but you
certainly are entitled to your own opinion of DRL's. The
discussion, however, was in regard to REQUIRING the use in
Pennsylvania of DAYLIGHT Running lights, not headlamps. Title
75, the Pa motor Vehicle Code, currently requires the use of
headlamps to see as well as to be seen, "From sunset to sunrise
and other hours of limited vision" If one perceives the
lighting condition is such that they need to be extraordinary
visible during DAYLIGHT, like when driving with the sun at ones
back, they can simply activate the vehicles headlamps. A
lighting system that does NOT cause confusion, at least that was
the conclusion of the Pa legislature when they rejected the
required use of DRL's, based on the engineering schools

You may want to read up on comments submitted to the NHTSA. Driver confusion
over the status of their lights is a fairly significant complaint...nearly all
referring to GM model vehicles. The recent addition of the "auto" feature
actually seems to have made the issue worse, especially during daytime fog
situations when the "auto" system sometimes works and sometimes doesn't and
DRLs reflecting in the fog being the only visual queue (too bright to see dash
lights) is a combination where a driver simply has no easy way to know if their
real lights are on (or not). Adding to that, in fog the lights might cycle on
one minute and off a few minutes later and back on yet again later. One MUST
use the manual switch and not rely on the "auto" (so-called) system when
driving in fog. Many GM owners haven't figured that out. By
definition...confusion. You may not even realize you're confused. You may
think your lights are on when they're not and you've never realized it.

Let them come on anytime GM wants them to. I as the paying customer I just

What is the problem with that??
Now, can anyone tell me how to turn them off when the specific need
Simple solution, ready?
1) Snip each DRL headlight power wire about 6" back from the bulb and
connect those wires to a "push to open" switch.
2) Route the return line from the "push to open" switch to the
relevant wire of your headlight bulb plug. (i.e. the one you snipped).
3) Discreetly mount switch, depress & hold to keep DRL off.
Lights will operate as normal until you depress the button.
This recommendation is for "off road use only" as per liability blah,
Total cost should be no more than $10 & 1 hour max.
On some GM vehicles the BCM will set a code with this solution and light the
"Check Vehicle Soon" light.

Exactly. The BCM thinks that the headlamps have "failed." On those
vehicles, the only real solutions are to reprogram the BCM (not really
an option without access to specialized equipment AND specialized
documentation) or to replace out the sensor part of the circuit with a
fixed value device. The latter solution of I have detailed in a
recent posting here.

I don't know if with all GM's the DRL turn off with the parking brake,
but if yours does, it would be much easier to install a switch in
parallel with the switch on the parking brake. Then you would also have
the reminder that they are off since the parking brake warning light in
the dash will be lit.
Huh? What? Speak up I can't hear you! ;-) Seriously, I can only
attest to my only vehicle with DRL, a 2000 3500 cargo van. In that,
there is no chime to warn about the parking brake, only a dash display

Read your state vehicle lighting laws. I'd bet that they specifically state
that the operator (driver) of the vehicle is the sole entity that is
responsible for the operation of the lights. I'd further bet that mention of
the the manufacturer (as having any legal role whatsoever in the decision of
when lights should be on or not) is totally absent. GM is insinuating
themselves in what the law clearly says is *your* decision, NOT theirs. Now, I
don't have a problem with "auto" lights...however the operator has a legal
right (in my opinion) to decide if they want total control or if *they* want GM
to control the lights. The decision is not GM's to make (even though they
apparently think it is based on their arrogant design choices to thwart the
owners rights in the matter!).
On my girlfriend's 2002 Buick Century, you can turn off the head lamps
after they have come on automatically, by manually turning on the head
lamp switch, then turning it right back off.
On my 2001 Z28 Camaro, you cannot turn the head lamps off if the car
thinks it's dark enough outside. You can of course turn on the lights
manually even if it is bright out, but that's not what you are asking
On my 1985 Dodge Ram pickup, the lights turn on and off via the manual
switch only. This is the way I like best.

My guess is that that is also the preference of a fairly large number of
people. Not sure why GM has yet to get it.
Take a hike. "Safety feature" my rear end. Gee, if it wasn't for my
lights coming on automatically, I just don't know what I would driving
at night! I might have to use the headlamp switch and uhh, I would
uuhhhhh probably never think to do that and then uuuuhhhhh I would run
into things in the dark. UuUuuUhhhhhhh.
