I loved it on my Monte Carlo, but on the Vette I never use it. It seems to keep the lights on all the time and since the Vette has the pop-up lights it just got too intrusive...

I've tried it both on and off. I rather like the convenience, so I leave twilight sentinel turned on.
I'm going to have to read the manual (say it ain't so) on the delay time to see if it only controls when the lights go off, or whether it also controls when the lights turn on.
To whoever said it doesn't make sense, plenty of cars have delayed off on the headlights. Makes it easier for people to find their way out of unlit garages, or to the front door, or whatever.
As for what is legal or illegal, some of you may not know this, but traffic laws vary from state to state (and sometimes county to county or even city to city). Now if Chevy could make a Corvette that knew where it was, downloaded all applicable laws automatically, and then would only let you do things that were legal in the current jurisdiction I'd be pretty darn impressed. Short of that, don't assume that just because the car allows it it must be legal.

most "fog" lamps arent fog lamps at all anyway, more of auxillary driving lamps which these are. hate to burst our bubble on "knowing what is legal and not".

4) If it was completely illegal to drive with only fog lights, the car manufacturer would not have made it possible to drive with only fogs.
And, FWIW, some laws are allowed to be broken. For example, you can break a traffic law when it's safer to NOT adhere to the regulation. For example, while you would normally get a ticket for driving down the shoulder of the freeway, if there was too much water from a heavy downpour in the normal lanes of traffic, you can be excused for driving on the shoulder. Similarly, you can get a ticket for driving 55mph in a 55mph zone if fog is so heavy that that speed is deemed unsafe for the conditions. The same holds true for fog lights. Typically, it is unsafe to run only fog lights at night because other drivers may not be able to see you well, due to fog lights being low-powered. However, if it's safer to run only fog lights, as might be the case in heavy fog, you can be excused.
Driving lights, on the other hand, are designed to assist in normal night driving, and are meant to be used in conjunction with low beams. In most states, it is illegal to drive with only driving lights. They MUST be used together with headlights. But, this is a moot point on this thread, because Vettes don't come with driving lights, and nobody was talking about driving lights.
Apparently.

There are many things that manufactures make possible that are illegal in some states.

In fact, many laws can be "overturned", for lack of a better term, depending upon the circumstances. The law is a beautiful thing, and so is freedom of speech. And, since this forum is not a courtroom, I see no good reason to argue my position any further. See you on the road!
Edit: Case in point - an action that causes physical harm to someone is also illegal, HOWEVER, can be excused under mitigating circumstances, such as self-defense.

I would use Twilight Sentinel if the delay was for turning on the lights. I'd like to get out of the garage at high noon without going thru the lights up/lights down cycle. But, alas, Twilight Sentinel is off for me.

And, you're right, if the delay WAS for turning them on, I would use the feature at times, too. I wonder why GM didn't think of that? It would've been easy to make that feature work for both, ON and OFF delays.
Oh well, if they had thought of that, they would've thought twice about the column lock/fuel shut-off thing, too!
Thanks for the clarification, to you and all the others that posted the same.

I don't use mine for the same reason since they come on everytime when starting up in your or any garage. Had to replace a one hightlight gear already and another one is starting to act up.What's up 3B?

not sure if anybody knew or had addressed this:
foglights work with the low beams only. (besides turning them on during the daylight hours)
if you hit the high beams to flash for passing or whatever or just turn on the high beams your fog light turn off automatically.
found this out on a road trip 2 wks ago..
FWIW
