Disabling daytime running lamps

My wife's daily driver is a 2003 Pontiac Grand Prix GT and it has the annoying DRLs. I followed the video on YouTube last night, I removed the fuse from the box located on the right side of the glove box and then I even went into the left side of the dash and unplugged the connector for the DRLs.

After I completed this, I got the annoying clicking sound under the dash, this is the lamps attempting to turn themselves off and on.

Is there another method of disabling the DRLs that will eliminate the clicking noise?

Thanks.
 
On the 01 i just pulled the fuse in the glove box and didn't bother with any harness.
Light switch works normally without the annoying PITA DRL. It does also disable the auto on/off feature.

Reduced bulb life and faster yellowing of the plastic headlight lenses from the heat.

Yeah, what's wrong with the DRLs? My Cobalt has them and the factory bulbs lasted 75,000 miles, so lifetime isn't really an issue...

As mentioned, shorter bulb life and headlight housing life.

My tax dollars seem to have found differently, according to IIHS in report DOT HS 811 029 (available here) when considering (1) two-passenger vehicle crashes excluding rear-end crashes, (2) single-passenger-vehicle to pedestrians/cyclists crashes, and (3) single passenger-vehicle to motorcycle crashes.

"The analysis found that DRLs have no statistically significant overall effects on the three target crashes. When combining these three target crashes into one target crash, the DRL effects were also not statistically significant"

Light trucks & vans did benefit from DRL usage in one of the crashes studied.
 
If its like my Cavalier, there is a relay in the dash fuse box. Thats the clicking as the computer cycles it. You'll be able to feel clicking in and out. You won't want to remove it as it does something else in the 'normally closed' position, but I forget what. Allows regular high beams or something.
Either way, what I did was pulled it, and cut the pins that lead to the coil. Should be a schematic on the relay itself. Then I reinstalled it, voila! No DRL, no clicking.

The OP didn't ask for an opinion on if its a decent safety feature or not he asked how to disconnect them.

They are safety feature for motorcycles that are mandated to use them like in Germany but once all vehicles are mandated it is not longer a safety feature for the motorcycle as it no longer stands out.

Not my opinion only this was the conclusion of a long term study done in Germany on whether it should be law for all vehicles, it was knocked down.
Agree or disagree there is another point of view.
 
I won't buy a car or truck without DRLs Sorry Ford.

I ride motorcycles and having the light lit will save you. This is an undisputed fact that I have experienced many times. The "studies" that say otherwise are simply hogwash IMO. With DRLs you can see a car or bike in your mirror or side vision or oncoming vision with a glance at dusk. You will see them in fog, rain, snow, darkness sooner. I'll take that extra XX% of being visible to the idiots who prowl our highways. Besides, when someone slams into the front end of your car or bike. Your headlamp life is greatly reduced.

Wrong...when you are in a crowd of traffic...maybe. But alone on a rural road at dusk traveling 55-60mph and that guy in the pickup truck who just glances to his right before pulling out in front of you...sees the DRL and steps on his brake? I have had 3 people tell me at gas stations, or a Dunkin Donuts. "Hey man it's a good thing you ride with your light on because I almost pulled out in front of you." Now this has been over a 40 year period. But how many people didn't bother to tell me?

All studies aside...I'll go with the guy(s) who almost hit me.
 
I turned off my DRL the first day I bought my car. My Volkswagen uses the low beam HID as the DRL. HID bulbs are expensive. I had to go to a VW tuning shop for them to turn it off via computer. My older VW's just had to tape over the pins on the backside of the headlight switch.

Don't get me started on the whole LED DRL craze. The new Kia's and Honda's are ridiculous!
 
Bulb life & headlight housing life are all baloney reasons to disable them.

They are usually under-volted and the sun's UV rays affect headlight lens longevity a lot more than a bulb will. The same goes for highway travel.

If you don't want them on then that is a fine reason but be warned depending on your state inspection laws you may fail for disabling a safety device.

Personally it doesn't bother me...

+1 They just blend in after a while. Those of us who ride bikes know how easily bke headlights are ignored by the dazed and confused on the roads today. I converted my parking lamps to LEDs to reduce power consumption and disconnected the drls which were just low voltage on the H4 low beam. Halogen bulbs are not designed for that. My led parking lamps draw much less current than the "drl" setup and have a very long life. They are switched off by the door switch so I don't have to bother turning them off when I leave the car.

Another study ignored by somebody who knows better. I rum my BM with the HIGH beam on and have had morons turn in front of me.

There's NO Federal mandate for DRLs, and I've not seen a state one yet, anywhere. BTW UNDERVOLTAGE is a sure way to kill a halogen cycle bulb, the halogen cycle doesn't work properly when the filament temp is low.

That is your opinion but for every pro DLR study there are studies that prove otherwise. I said studies show they are a safety feature for motorcycles.
If i buy a car that has them they are gone the same day.
 
I've always believed if small lights help you see the much larger car better in broad daylight, your eyesight is either too poor to be driving or your not paying enough attention because the lights generally run dimmer in the day so they really don't do anything to help. On my car I also have DRL (2003 Corolla), the worst feature I've seen on a vehicle, not in function, but design. I hate not having full control over my lights, it's very frustrating, but found that bringing the parking brake up to the first click, BEFORE turning the key, they won't come on. The hand brake is wired in as a switch, so if it's engaged before the key is turned, they will not come on. Now before people start assuming I'm driving with the brake on, no I'm not, the hand brake does not actually engage and brake until you go up several more clicks(depending on how loose you have it adjusted). Having it in the first click it's far enough up to trigger the brake light and open the DRL switch, but not far enough up to provide any braking or rubbing. And yes I drive this way during the day, yes I've felt my drums after a few hours of driving around town to see if they were hotter than normal, no, cold as the body, just as it should be. Besides if you grab the park brake, pull up, you'll find you can go through several clicks before meeting resistance, this is when it will rub, as a design safety, the shoes shouldn't contact drums for at least 2-3 clicks, there's too many dummies, which may "accidentally" not drop the brake all the way down before taking off. Overheating drums and possibly causing unwanted warranty claims, hence the need for a few clicks of room before actually engaging.
This is what works for me, I don't have to do any unnecessary work, remove any fuses, and when you want light, just let the brake down from its one click up, and on comes the lights. My mother also does this in the morning before leaving, while warming up the engine, she doesn't want her headlights shining into the Windows for 5 minutes, then just after pulling out let's it down.

Yeah, motorcycles are a different story. When everyone has DRLs though they just fade into background noise again.
Notching the park brake up to the first notch worked on my Cavalier, too. Bit harder on a foot pedal park brake, though.
