    I have a friend of mine that for some unknown reason HATES DRLs. I have them on my Silverado and give them zero thought until he brings them up.

    He rants on how bulb life is reduced and how it impacts his gas mileage. Seriously, does anyone think that when the DRLs are on that it significantly impacts their fuel economy.

    I had a 2008 Silverado and now a 2013 Silverado and I have never even needed to touch the headlight switch. The DRLs are on during the day and the headlights switch on when it gets dark.

    As far as bulb life, I had to replace one bulb in the 4 years I owned the 2008 Silverado. My old 2002 Explorer Sport Trac did not have DRLs and had manula headlamps and I had to replace both headlights twice in that vehicle, and to boot the Sport Trac with a V6 engine got worse fuel economy with cr@ppier power than either of my Silverados.

    I have should have DRLs, but they don't work (original owner must have messed with them) so I drive at all times with my headlights on. I like knowing people can see me and its nice having the dash illuminated all the time. I know some think this puts too much draw on the electrical system, but were only talking like 25-30 amps total with brake lights, park lights and headlights as well as interior lights. My factory alt is rated at 100 amps and I only see the voltmeter drop when I put the defroster on while running the blower on high and such. (after my big three upgrade)

    IMO, DRLs might make a vehicle 1% safer in an oncoming traffic situation and probably use 0.05% more fuel. Because of this I give DRLs almost no thought unless someone else brings them up. If a vehicle had DRLs OK, if it does not OK, makes no impact on my buying decision.

    Now what I do REALLY like is automatic headlamps on a vehicle. If a vehicle does not have automatic headlamps that does impact my buying decision.

    I don't give it a second thought. Clearly your friend is overly concerned with pinching pennies if he cares about replacing a 3-5 dollar bulb every 4 years and saving however much gas it takes to activate the alternator just enough to supply only the power used by said bulb across the entirety of a given average drive.

    Want to get his goat? Talk about how much energy he wasted thinking and b1tching about your DRL's and how it could have better spent on a real problem in the world. That should shut him up. :)

    I have the park light type drl on the early to
    mid 00' trucks and replaced them with amber sylvania long life bulbs about 6 years ago. I like the amber with my black truck and brush guard. As for fuel milage thats crap and probably not even measureable. Ask him how early he turns on his turn signals and how over the life of the bulbs that kills milage, or dome lights, or radio volume, or how driving not directly N,S,E,W wastes gas as the compass has to illuminate the NW, SW etc etc. You could go all day about that bs....

    my 2000 SILVERADO uses 66 amps with the ac on max and the headlights on . I measured the amperage . DRL lamps draw about 5 amps max .total ..

    Then my estimate of 25-30 amps for just lights seems accurate.

    I think he's more concerned that GM is "making" him have his headlights on. As I said, I don't even give DRLs a thought until someone else brings them up. If you Google "hate drls", you get a lot of people complaining about them. Seems to me that people have more time on their hands to complain about trivial stuff.

    I told him he needs to get a vehicle that has no computer at all.

    But he wouldn't want the DOT required night reflectors they make him have.

    Motorcycles must have DRL's so why not cars and trucks. I hope they make DRL's a law on all vehicle. Too many people driving in rain,fog, at dawn or dusk with no lights. Many states have a law thet when wipers are on the lights must be also.

    In 1996 the DOT began to require all cars to have DRLs. In CT you must have your headlights on while the wipers are on. No one follows either rule.....

    Under certain lighting conditions, DRL's/headlights can be the difference between life and death, literally. A drunk driver coming the other way on a two-lane highway at dusk may not see your car when he pulls out to pass someone, but he just might see the DRL's/headlights. If I had a car without them, I would always have my lights on.

    As for the automatic headlights, I will not own any car that does not have them. I wired my '65 Dodge Coronet to have the lights on anytime the engine was on, so I am pretty serious about that.

    Ask your friend how often he turns off the engine at a longer-than-average red light....that actually does save gas, and lowers overall emissions, but I'll bet he never does it.

    But if "someone" wants to, just pull fuses #31 and #33 from the under-hood fuse box and they are off. This doesn't affect the automatic operation of your headlights.

    My DRLs bulbs burned out years ago and I haven't replaced them.

    To me, DRLs are a solution looking for a problem. 15 or 20 years ago, when very few cars/trucks had their lights on during the day, yeah they stood out. But today, if every car has their lights on all the time, then all the cars look the same, just like they all did when no cars had their lights on during the day, so what's the point? And what's next, flashing lights? So, all cars have their lights on and in order to stand out, a few cars start using strobe lights. OK. So, 10 to 15 years from now, all cars have strobe lights and we're back to where we are now. Seems silly to me.

    This is a false example. The problem in your example is that there is a drunk driver, not whether or not someone has lights on in the day time. Drunk drivers kill, no head lights.

    I have a better example then. There have been countless times in my neighborhood where a new car that didn't have DRLs has pulled out a few streets away from me and I couldn't see them because their car is a neutral color/dark (there are a lot of trees and fences in my area) so when I look to pull out I don't see them until seconds before I pull out and I need to slam on the brakes not to hit them. I look very carefully multible times when pulling out. DRLs/headlights on make it 10x easier to see another car coming down the road day or night. Even just park lights are enough.

    The worst time of day for this is after dawn or before dusk when everything seems to be a neutral color. I keep my lights on just to prevent someone from hitting me! There are just too many blind intersections, hills and corners in CT and the whole New England region. Of course a new CT law states you can't pull up from the line if you can't see at a stop sign or turn on red to see better so you need to stay put until you can see its safe to go.. But by definition of the law you can't see so you can't go....

    As I said, maybe DRLs make a vehicle 1% safer, I don't know. I however don't think DRLs make a vehicle less safe.

    A vehicle having or not having DRLs would not impact my purchase decision whatsoever. I do insist on a vehicle having automatic headlamps.

    DRLs wouldn't impact my purchasing decision either. Like you said, it does no harm if the vehicle does have them. But likewise, automatic headlights are must.

    Another good question for your friend is if he has an aftermarket stereo in his car. If he's so worried about extra power draw reducing his fuel mileage, a more powerful stereo, even just the head unit, would pull more power than DRLs.
