Lights don't go on automatically in Australia, but the prevailing wisdom is that if you're driving in the country you should keep them switched on even in the day. Nobody does it in the city or suburbs, though, and I'm not really sure they're wrong.

Having your lights on whenever you drive is the norm here and it makes a car 1000x easier to spot, sometimes I've almost been surprised by a car because it's lights were off and it blended in so well with the road and surroundings. But if the car has the lights on, you'll spot it hundreds of meters away even if it's not in your direct field of vision thanks to the lamps. It's just such a loving useful thing I don't understand countries where they drive with the lamps off. I think the cops would stop you here if you forgot it, and cars will blink at you to say "hey dude you forgot the lights".

Atlanta simplifies things a bit in that you can just assume at any given hour the roads in both directions are solid lines of cars.

Jabor posted:Pretty much just big white goods at this point, I think. Perhaps some older kitchen appliances? Virtually everything these days has an actual microcontroller and hence at least some circuitry to turn AC into low-voltage DC. And a lot of portable appliances use that power circuitry to power the entire device, so you get it to be 110/230V agnostic for free. Electric heaters, electric stoves, blenders, mixers, toaster ovens, compressors, incandescent bulbs, fluorescent fixtures (they *can* run off DC of sufficient voltage, but if you do that the mercury tends to accumulate at one end of the lamp so fluorescent fixtures that run from DC actually use an inverter to convert to AC first). Think anything that's a big resistive or reactive load. Obviously running the resistive stuff off DC wouldn't be a problem, but the reactive stuff would be. spankmeister posted:Don't listen to this idiot.

Electronic ballasts do, yes, you find those in CF lamps. The old-style fluorescent tubes still frequently use equally old-style reactive ballasts.

Mikl posted:Personally I just have my headlights on every time I'm driving, even during the day. Am I weird for doing this? Same here, but only because I I replaced my headlights with LED bulbs. I have DRLs, but when they're on/the lights are in the "off" position, it sends a lower volage through, and it causes LED bulbs to flicker, so I have to turn them to 'on' to stop that.

Not even a residential neighborhood; it was on a two-lane road leading to or from an interstate. I enjoy Detroit more than Atlanta.

Phanatic posted:That's not borne out by actual research. That is the only study that found no effect that I could find. From Daytime running lights in the USA: what is the impact on vehicle crashes in Minnesota? quote:Daytime running lights (DRLs) are a safety feature intended to reduce crashes by increasing the contrast between vehicles and the background. Currently, Finland, Sweden, Norway, Canada, Denmark, Hungary, and Iceland all require vehicle lights during daytime hours. Most of the studies of the effectiveness of DRLs have been done in Scandinavia. Finland was the first to institute DRL legislation in rural areas, and literature reports a 27% crash rate reduction [1]. In 1977, Sweden started requiring the use of daytime vehicle lights on all roads, and reduction of crash rates from 9 to 21% were reported by Andersson and Nilsson [2]. Norway began to require installation of DRLs in all new cars beginning in 1985 and use of daytime lights on all vehicles by 1988. A 15% crash rate reduction for crashes involving more than one vehicle was later reported by Elvik [3]. Lastly, Denmark has required use of DRLs on all roads since 1990, with a statistically significant 37% rate reduction for crashes involving a left turn in a study by Hansen [4]. A 1995 paper by Theeuwes and Riemersma criticized the odds ratio methodology of all these early studies [6]. In response, a meta-analysis of 17 studies by Elvik estimated a decrease in crash rate of 10–15% for multi-vehicle crashes and total crash reduction of 3–12% [7].

DrBouvenstein posted:Same here, but only because I I replaced my headlights with LED bulbs. "Plug and play" LEDs have the same problems as ebay HID kits. The optics of your light assembly aren't designed for the light pattern emitted by an LED bulb. It may look brighter, in fact it probably does, but that brightness is almost certainly not being used optimally and is probably worse in at least one way (glare, foreground illumination, etc.) Right now there aren't really any good retrofit projectors for LEDs. The Toyota Corolla units are widely available but are generally considered to be worse than a standard HID projector retrofit. That'll eventually change of course, but a lot of the OEM LED lights aren't actually all that good either.

I've noticed that foreground and just off to the side illumination isn't as good, but I have fog lights that I always keep on that fill in those areas. I also only replaced my low beams, not my high beams, so mostly just in-town driving where there's street lights.

Alereon posted:I have been almost run over several times because of forward-firing LED turn signals that are completely invisible from the side, especially on a sunny day. It's ridiculously unsafe. Unfortunately the cheapest LED modules out there don't do this and just have a single LED aimed out. These are pretty terrible for basically everything except maybe license plate illumination, but idiots buy them because they're just want "LED" and don't really care how they get it. DrBouvenstein posted:Hmmm..interesting. I've noticed that foreground and just off to the side illumination isn't as good, but I have fog lights that I always keep on that fill in those areas. I also only replaced my low beams, not my high beams, so mostly just in-town driving where there's street lights. For a normal headlight less foreground is actually a good thing. The area that fog lights cover really shouldn't be covered by normal headlights because at speed that nearby brightness hurts your distance vision. With PnP LEDs the usual problems are too much foreground, too little distant output, and a certain amount of glare (though less than a HID bulb in halogen optics).

Anta posted:That is the only study that found no effect that I could find. Living in MN, I can say that before DRLs became standard, it was really common to see people driving in twilight without lights on, and by the time you noticed the car, it was blowing by you. I would chalk it up to people who started driving when headlights weren't necessary and didn't go by enough cars to notice that they actually need headlights until it was super obvious. Also, and this is anecdotal, but I've heard people remark on how quickly it goes from full sunlight to total darkness compared to elsewhere in the U.S., so there's more of a chance of needing to turn headlights on en route. Not sure if that's a north/south or a coasts/flyover country thing or what, but I could see there being variation in usefulness based on location.
