RE: Are there definitive studies on effectiveness?

Quote: I'm hoping she realizes that the DRLs are only up front...

When DRLs first appeared in the '90s, I remember seeing lots of cars with dim-looking headlights and no taillights at night. You'd think they'd notice the pitch-black instrument panel in front of them...

I'd certainly believe that running the headlights imposes an extremely marginal loss of horsepower. However, a car that's totaled because someone didn't see it turning left makes 0 horsepower.

LIGHTS OUT !!!

I hate daytime running lamps


#1 because when I drive home from the city I have 3 pitch black intersections that I come to... when I approach these crossroads I turn my headlights off for a second to see if I see any lights coming thus affecting my next move.

#2 because I don't like to advertise myself.

#3 I am a good driver... I know when my headlights need to be on for safety

#4 I am annoyed by vehicles with DRL on a nice sunny day therefore I choose not to annoy others who feel the same as I.

#5 headlight wear is impacted if DRL are incorporated into normal driving lights (hi/lo beams).

#6 some manufactures have DRL who come on always so that in a parking lot while their vehicle is running I am being blinded.

#7 some morons drive with only DRL after dark

#8 I like to drive up my driveway with my LIGHTS OUT!!!

#9 When riding at the local lights festival or in a parade, DRL take away from the effect. DRL certainly don't affect my insurance rates (yet)

#10 This country (USA) is supposed to be a free country but DRL are just another item to add to our growing list of freedoms taken away (and the sad part about this is that the government has nothing to do with it. (yet)


DRL are good for one thing and one thing only!

since drivers licences are so easy to get, there are many many bad drivers on the road today many of these drivers are too dumb to realize that headlights are not just so that you can see to drive but that lights are also necessary to be seen in inclement driving conditions and yet I see people driving a dark gray car in the driving rain with no lights.... these are the people who need DRL.

These two points seem a little contradictory to me. How is approaching an intersection in pitch black conditions with no lights on safe?

Suppose there is another car with no DRLs and no lights on approaching the intersection at the same time as you, how will you see them? Just as importantly, how will they see you? What if turning your lights off for that second causes you to not see a new regulatory sign?

re,re, lights out

That is a chance I have been taking for about 20 years now and never had any close calls, negative incidents, or seen any new signs..... Thats a chance I'm willing to take because my "check" system works for me and on many occasions this has alerted me to the presence of an approaching vehicle...

OK here is another issue - MOTORCYCLES.... do you remember when motorcycle companies started putting always on lighting on their bikes that was way before the DRL era on vehicles... motorcycles were much easier to see because they stood out due to their lights now they just blend in.

Not that I want to bore anyone BUT- Just yesterday it was 60° & sunny I was sitting in line at a 3 way stop sign... there were about 10 cars ahead of me...as I watched the cars on my left turn right the DRL equipped vehicles were blinding me when they made their turn- especially the cars that incorporate DRL into the high beam.... it was only 3 cars but for an old-schooler like me it was three too many... OK you can tell me not to look at the lights or something... Great suggestion but that is not realistic.... and truthfully I have no problem with someone who turns their lights on every time they start their car... even DRL for someone who really wants that feature because THAT IS WHAT THEY WANT... but I think it's becoming an annoyance epidemic that the feature cannot be overridden by switch then again the first thing I do when I get a new car is disconnect all chimes, beeps, dings, etc... because I am annoyed quite easily:o)

The lights go out just long enough to see if there are any approaching headlights... It's not like I sneak up on these intersections....
I have been driving for 24 years now and had one accident when I was 16 and thats it... I don't speed, or tailgate.... I am extremely safe & courteous in all regards of operating a motor vehicle

RE: LIGHTS OUT !!!

I know of no vehicle manufacturers that use the high-beam headlights as DRLs. The people you see with "glaring" headlights have more likely tripped the turn-signal stalk by accident and activated their brights (which, on some models, happens whether the DRLs are on or not).

DRL

If your car has daytime running lights (DRL), you can not turn them off. They will be on whenever your car is running. (In some cases, the lights come on when you release the emergency brake or when you shift out of "park.") DRL is intended to make your car more visible and will not otherwise hurt your car. You may burn out the lights a little more often and you will use a tiny bit more gasoline, but those are the only negative effects.

The very essence of daytime running lights is that they are always on when the engine is running. That's what they mean when they say both "daytime" and "running." As to whether they hurt your vehicle, it depends on what you mean by "hurt."

You will most likely find that your headlights have a reduced lifetime, since they're always on, although most manufacturers attempt to alleviate this problem by running them at reduced brightness - something like 50-60% in most cases.

As discussed above, the load on the car's generation system will have an incremental impact on your overall gas mileage, although since you can't turn them off, it's a "how can you tell?" kind of calculation. The common argument that our country would save NNN gallons of petroleum products every year is usually overstated, and it always neglects to allow for the petroleum products used by emergency vehicles making runs to accidents that might have been avoided with DRL.

After all, the purpose of daytime running lights is to make the vehicle more visible to other drivers and other people on the road (including pedestrians). I've seen many an idiot driving a "road-colored" car in fog, rain, and semi-darkness without lights because s/he's afraid s/he'll forget to turn them off when s/he gets to the office; or simply because s/he figures that "I can see everything so everybody else must be able to see me." Forcing such people to have lights on at all times probably saves a several accidents and a few lives every year, although Darwinists might argue about whether it improves the species to have the "drive-in-the-dark-without-headlights" gene preserved.

So "hurt" the car? It's intended, as I understand it, to reduce the likelihood of accidents, which is probably a "good" thing instead of a "hurtful" thing, at least in the long run.

HTH.

DRL studies in Canada

The best data is on the Transport Canada websites, where stats compiled in the 80's/90's indicated-as I recall-about a 30% decrease in accidents in two lane marked but physically undivided hwy. head ons..i.e, Trans.Canada Hwy.
For some reason, it concluded, the brain tends to view approaching objects on a long flat sloping road as relatively equal, and searches for peaks or changes diffrerently, i.e less effectively the longer the potential viewing area is in miles/km., so despite wider spaces of the West in particular, these kinds of areas are where we tire, or or brains don't pick out long range objects, even though you'd think a barren landscape would make for easy pickens!!
I can't stand the fact DOT didn't mandate them for US cars, and think, FWIW, that xenon driving lights should be standard, hell be cost, so that I can show I'm coming around corners with an adjustable driving light beam (Lexus and others are incorporating this update on Citroen turning headlights, but the current designs use HID for the DRIVER's benefit, NOT to warn the traffic coming the other way that doesn't see you and then suddenly gets blinded by your massive hot spots of lumens!!

The idea of a light is not so bad but where will they stick the battery??

RE: Your Opinion On Daytime Running Lights

The daytime running lights run your battery down to the point where a five year battery here in the south is probably good for two years.

RE: Your Opinion On Daytime Running Lights

Most daytime running lights use too much electricity. Most use 100 watts. How many homes leave 100 watt light bulb on during the day or even all night. Try touching a 100 watt bulb and you will get scorched.

They are profitable for manufacturers. I was forced to get DRLs when I upgraded to Leather seating. The DRLs cannot be switched off unless you rewire some circuit board.

Some nights I forget to turn on my headlights my dashboard stay lit up all day with DRLs.

The manufacturer should give you a disable switch and the ability to switch to 10 watt LEDs. LEDs are cool especially on the new AUDIs. I don't mind paying extra for cool LEDs.
