When your DRLs are active the current is routed through a large resistor to the high beam lamp. This means that you get a dim high beam. This allows other drivers to clearly see the lights as they are pointed more towards them than the road. By running them dimmer you do not get blinded by oncoming DRLs.

That would be hard to do. When the DRLs are active your dash and marker lights are not on. As well, your high beam indicator light is dimly lit. The DRLs shine very little light on the road. Remember, they are your high beams running at a lower voltage.

On most cars DRLS are the High Beams run with low power. In Canada we’ve had DRL for about 10 years now. But my 99 Intrigue is the first car I’ve had with auto-headlights turned on upon darkness. At first I didn’t like it but I’m used to it now. Sometimes I would like the lights off while moving though, like when pulling into a residential driveway late at night.

I believe you can also push the dome light button 4 times and the lights will go off. Pain in the butt but it works. (I haven’t tried this in a while on my 2000 Silverado so I may be wrong).

Gary. It’s the same thing. The automatic headlamps are part of the DRL system and it is standard on all GM vehicles. There is no twilight sentinel. It is built in. Most people like it. Wojo

No, you’re right. It’s a recent change and only works in Silverado/Sierra’s to my knowledge. It disables the whole system until you do it again. Wojo

I think I know what you mean but not exactly. Daytime running lamps have the headlamps on to some intensity – usually reduced, at all times. Not this does NOT mean the tail lights are on. Twighlight sentinel switched the headlights and taillights on to full intensity when it gets dark. (Or theoretically dark
Response:
> No, he’s not talking about the daytime running lights. > He means that "pain in the ass" automatic headlight sensor > that switches from the DRL’s to the main headlights.
My 98 Regal has these, and it is the DRL module. It controls when the DRLs are on and when the headlights come on. I had the opposite problem, the headlights didn’t come on until I thought it was too dark. I fixed the problem by putting a piece of smoked celophane over the sensor that is on the dash. Now the lights turn on sooner. To make it go the other way (turn on the lights at a darker setpoint) it won’t be as easy. When it’s dark out, the sensor resistance is large, on the order of a Megohm. When it’s bright, the resistance is low, probably a couple KOhm. To change to a darker setpoint, you will need to reduce the resistance of the sensor. Perhaps you could find a small magnifier lens to try to increase the amount of light coming into the sensor. If you have any electronics expertise, you could probably take the DRL module apart and see what’s going on. Perhaps there’s a pot in there that can be adjusted. If someone has a spare module, I’d be willing to take it apart to see what I can do. Good luck, -L http://members.nccw.net/webe – WebElectric Magazine

My headlights have never came on even thru the long mountain tunnels in Penn. Maybe try a new sensor. I love my auto headlights and would not trade them for anything!! Anytime day or night.

Nope, the trigger level is not adjustable.

There is a way to disable them but there is know adjustment.

Response:
No, he’s not talking about the daytime running lights. He means that "pain in the ass" automatic headlight sensor that switches from the DRL’s to the main headlights. There’s a short delay, for shady spots and tunnels during the day, to keep them from blinking on and off every time you go under a tree, but it is way too sensitive in my opinion (and Steve K’s and probably thousands of others). I get stuck in a bright/dim section of secondary road with afternoon traffic. People in front of me must think I’m pissed at them or ignorant because my lights usually turn on then off 2 or 3 times while in that 5 minute stretch. Clicking the parking break on a notch or two will shut them off, but I’m not about to ride around like that. I wrote to Chevrolet asking if there was a fuse or other way to override the switch and use manual headlights. No response (go figure!). The other alternative might be to manually put the lights on permanent in locations that cause them to alternate (anything’s better than blinking) and look like a moron, even during the daytime. I assume the little sensor on the dash will put the lights on even earlier once a nice layer of dust builds up over the lens. Glad to at least hear it’s not just me bugged by this.

> > On most cars DRLS are the High Beams run with low power. > What?? Describe this, please!
When your DRLs are active the current is routed through a large resistor to the high beam lamp. This means that you get a dim high beam. This allows other drivers to clearly see the lights as they are pointed more towards them than the road. By running them dimmer you do not get blinded by oncoming DRLs.
Response:
My DRLs are the low beams, normal power. When I turn on the headlights, the yellow parking lights come on as well. That is the only difference, other than the taillights. Same power on or off.

It’s daytime running lamps. All GM vehicles have them now, Canadian or otherwise. There is, to my knowledge, no way to adjust them other than to disable them and use the manual headlamp switch.

My 98 Regal has these, and it is the DRL module. It controls when the DRLs are on and when the headlights come on. I had the opposite problem, the headlights didn’t come on until I thought it was too dark. I fixed the problem by putting a piece of smoked celophane over the sensor that is on the dash. Now the lights turn on sooner. To make it go the other way (turn on the lights at a darker setpoint) it won’t be as easy. When it’s dark out, the sensor resistance is large, on the order of a Megohm. When it’s bright, the resistance is low, probably a couple KOhm. To change to a darker setpoint, you will need to reduce the resistance of the sensor. Perhaps you could find a small magnifier lens to try to increase the amount of light coming into the sensor. If you have any electronics expertise, you could probably take the DRL module apart and see what’s going on. Perhaps there’s a pot in there that can be adjusted. If someone has a spare module, I’d be willing to take it apart to see what I can do. Good luck, -L http://members.nccw.net/webe – WebElectric Magazine

Why not turn yer headlights on with the switch for this stretch of road? BTW, I love my auto headlights, nifty little invention.

No, he’s not talking about the daytime running lights. He means that "pain in the ass" automatic headlight sensor that switches from the DRL’s to the main headlights. There’s a short delay, for shady spots and tunnels during the day, to keep them from blinking on and off every time you go under a tree, but it is way too sensitive in my opinion (and Steve K’s and probably thousands of others). I get stuck in a bright/dim section of secondary road with afternoon traffic. People in front of me must think I’m pissed at them or ignorant because my lights usually turn on then off 2 or 3 times while in that 5 minute stretch. Clicking the parking break on a notch or two will shut them off, but I’m not about to ride around like that. I wrote to Chevrolet asking if there was a fuse or other way to override the switch and use manual headlights. No response (go figure!). The other alternative might be to manually put the lights on permanent in locations that cause them to alternate (anything’s better than blinking) and look like a moron, even during the daytime. I assume the little sensor on the dash will put the lights on even earlier once a nice layer of dust builds up over the lens. Glad to at least hear it’s not just me bugged by this.
