i see some guys drive with them on during the daytime .what do the rest of you guys do?

 

An option on the C5s was daytime running lights. They called it "Twilight Sentinal". We can turn the feature on or off with the options button on our DIC. When the option is turned on our parking lights in front is on during the daytime.

 

mmmmm the parking lights are always on, daytime running lights were not an option they were standard and are always be on (unless disabled manually). Twilight sentinel is automatic headlights which will turn on your headlights automatically when its dark enough.

 

Yes, Daytime Running Lights (DRLs) are standard on all C5s and are always on whenever the exterior lamps (i.e., headlamps and/or parking lamps) are off for all domestic C5s as they came from the factory. (For C5s built for export to some other countries, the DRLs operate differently and do not stay on constinently.) There are several ways of disabling the DRLs on the domestic models which a number of people have done:

How to disable DRL

 

I think he means the fog lights?

 

The easy way to disable them is to pull the A2 fuse. You get 3 DIC codes with this method.

Theres a more permanent fix that installs a jumper in place of the 38 and 40 relays. That allows the full approach light feature to operate and there are no DIC codes tripped.

Mine are disabled as amber DRLs are illegal in Europe and my car is modified ready to go back to UK.

 

sorry guys what i meant are the approach lights .as you go through the setting it has an option for running approach lights [daytime lights-parking lights]to be on or off.since you can set them either way ,i was wondering which way most of you have them .i kinda light them on but just wanted to see what alot of you guys think also.since 1/2 i pass have them on and they others dont.

 

The day time running lights are not the approach lights
That option is to have the outside lights come on when you unlock the door with the key FOB.
Read your owners manual to find out more.

 

i maybe wrong but i dont think so ,but by choosing the option approach lights[on or off] they stay on all the time .when u choos yes

 

I think so

See this poll about the DRL a few post down if you want to know what most people do http://forums.corvetteforum.com/show....php?t=1452744

 

No, StephenT and the information he provided above is correct. The approach lights, when this option is turned on, only light up when you press the UNLOCK button on the key FOB. Too, they only light up for approximately 30 seconds after pressing the UNLOCK button and only when it is dark outside. Their intended purpose when on is to provide some light as you approach the car in a dark parking lot or the like. Turning this option on in the DIC does not keep them on while driving in the daytime or night. Here's the description of their operation from the 2003 Owner's Manual:


cenzo mentioned the fog lamps in his post above. The fog lamps (if your car is so equipped - they are optional equipment for some model years) use the same lamps as the DRLs but are operated from a separate switch on the instrument panel just to the left of the steering column. Keep in mind that at night when you turn on the exterior lamps (headlamps and/or parking lamps), the DRLs are automatically turned off. The fog lamp switch allows one to turn the Fog Lamps/DRLs on during nighttime conditions, as needed. Here's a description on the operation of the fog lamps from the 2003 Owner's Manual:

And here's a description of the DRLs and their operation from the 2003 Owner's Manual (Note that the DRLs, fog lamps and front turn signals all use the same 2 front lamps):

The owner's manual is not all that clearly written and playing with all of the lamps should give you a better understanding of how they operate.

Hope this helps!

 

Just chiming in - what he said.
