What is the difference(s) between the day-running mode from the headlights used at night? In other words, when I switch my headlights on I can't tell the difference between that and the day-running mode. Do other lights not come on in day-running, but do light when I "turn on" my headlights? Is the light (i.e. beam, or strength) from the headlights different in each mode?<p><br>Chronic<br>2001 V70 T5 manual<br>K&N High-Flow Air Filter<br>fingers crossed<br>

Re: Day running headlights vs. night headlights...? (Chronic)

Usually, DRLs are a low powered high beam. They turn on every time you start the car and none of the other lights (dash and rear tail lenses) turn on.<p>There are some vehicals out there that use full lights as DRLs. It might be the case for you.<p>RJ

I seem to recall the DRL's on my dad's car are around 85% of full low beam headlights.<p>Technically you could say Volvo has had full strength low beam DRL's since '86 in the 240! You can turn on your headlights and just leave them on ALL the time, and when the ignition is turned off, the lights all go out. But of course you could still run no lights or just parking lights too.

Re: Day running headlights vs. night headlights...? (towerymt)

So, I don't really know if we can consider that true DRL.....it's pretty much leaving the headlights on.

That leads me to this question...What is best, leave the lights on all the time knowing they shut off when I shut the engine off, never turn the lights on because "what's the difference?", or use them the way we've all been taught (i.e. keep 'em off when it's day, turn 'em on when it's night) AND FEEL LIKE A COMPLETE A-HOLE knowing I'm not doing anything, except flashing my lights!<p><br>Chronic<br>2001 V70 T5 manual<br>

VW's have a lower intensity high beam for DRLs. I had these on my Passat until I upgraded to HIDs.<p>RJ

When you are behind someone (with your lights on) they will notice you and are more apt to react to you. When you are going to pass on a one-lane road with no divider/median separating the two opposing lanes, oncoming traffic is going to notice you a lot faster. You will also be able to judge more accurately where the oncoming car is if their lights are on.<p>DRLs work...whether you feel comfortable with them or not. Why do you think more and more companies are adding them...becuase of marketing pressure or because they are documented to make the difference?<p>Yannis<br>

Re: Day running headlights vs. night headlights...? (GrecianVolvo)

Sorry Yannis,<p>I'll agree to disagree. Especially on your line about "I am not talking about a motorcycle and I could care less about that." You seriously don't care if your DRL's make another class of road user less visible?! I'm somewhat incredulous...<p>As far as DRL's working, you may find some of the following links on DRL's interesting reading.<p><A HREF="http://www.motorists.org/issues/drl" TARGET="_blank">http://www.motorists.org/issues/drl</a>/<p><A HREF="http://www.motorists.org/pressreleases/drl_petition.html" TARGET="_blank">http://www.motorists.org/pressreleases/drl_petition.html</a><p><A HREF="http://www.mrf.org/articles/1998/daylite.html" TARGET="_blank">http://www.mrf.org/articles/1998/daylite.html</a><p><A HREF="http://www.safespeed.org.uk/~dadrl/Danger%20at%20any%20speed.html" TARGET="_blank">http://www.safespeed.org.uk/~dadrl/Danger%20at%20any%20speed.html</a><p>especially section #4<p>If you do a Google search on DRL, DRL's Daytime Running Lights most of the links you'll find are about how to turn them off. Other points of note include:<p>Australia abandoned DRL's after finding they did not significantly decrease crash results.<p>US and Canada both saw a 12% decrease in traffic accidents over the same reporting period. Canada mandates DRL's, the USA does not.<p>Sweden and Britain have almost identical accident rates per million miles. Sweden is slightly higher (65/million miles) mandates DRL's, Britain (64/million miles) does not.<p>The EU mandates NO DRL's for the 2002 model year onwards.<BR><BR>

Sorry. <IMG NAME="icon" SRC="http://********************/smile/emsad.gif" BORDER="0"> To get back on track before I wear out my welcome...<p>I don't think it really matters. I leave my T-5 switch in the "lights on" position that way I'm never wondering why my high beams don't work at night, Duh! <IMG NAME="icon" SRC="http://********************/smile/emsmile.gif" BORDER="0">

Won't it cause more stress on the car when you leave the lights on during startup? I mean it's not like trying to crank up the car with the AC at full blast. The car would be in pain. But something to that extent?

Re: Day running headlights vs. night headlights...? (mike_c70)

That's conventional, but in this case the lights are always on. Even if one switches the dial to the off position, the DRL mode causes all the lights to be on as soon as the engine starts. Then (just to be safe) I switch the lights "on". Nothing really changes except the lights have to endure the sudden on/off stress resulting from being swithed from the "off" position to the "on" position (through the parking lights position). That's what I don't feel good about. <IMG NAME="icon" SRC="http://********************/smile/emcrook.gif" BORDER="0"> <p><br>Chronic<br>2001 V70 T5 Manual<br>K&N Air Filter<br>
