My Yamaha XTZ750 has a small bulb in the lower part of the headlight reflector, my BMW E34 with projector headlights has a bulb in the upper part of the headlight, and my Camaro has separate lights in the bumper cover (shared with the turn signal, side marker lights, and DRLs). All of these lights are what I call parking lights. You may call them whatever you want, but the point of the matter is that it's illegal to drive around with nothing but them on. Of course, the are allowed to be on in combination with the headlights, fog lights, etc. > > There are no requirements to have or use parking lights or city lights > anywhere in the US that I am aware of.

I don't know where you live, but here the weather isn't just hot and sunny. There's rain, overcast, fog, snow, etc. and in all of those situations high beam DRLs are too bright. Likewise during dusk and dawn. "Angle eye" DRLs, just like the LED DRLs on Audi's, are a great idea on the new E90 IMO. > > If you're saying that you are using your DRLs at night (instead of your > headlights) and that is when there is a glare problem, then you are > obviously using your lights incorrectly.

I kind of doubt that this is true. I'm sure you do, but there's no way you can get high beam DRLs approved as DRLs in "ECE-land". IIRC the maximum light from DRLs in Europe is 800 cd, while in NA it's 7000 cd. That should tell you something... > > Ulf |

Boy I wish cells were illegal in moving vehicles. They are in the UK. Unless you have a proper hands free kit. But it made absolutely no difference to the numbers using them as it's not enforced. And despite them now having been around for many a year, plenty still can't multi-task with them. So the driving gets neglected. -- *Money isn't everything, but it sure keeps the kids in touch.

Or the multi-tasker who lost control on a 2-lane road this past July. She was drinking coffee, using her computer and cell phone and eating a snack. That person hit two people on bicycles, killed one, put the other in the hospital and ruined her own life. My wife was on the same bike trip; but won't be doing that again. Too bad. You can't legislate common sense and what about smart people whose priorities are screwed up and just don't get it? I'd like to see devices in cars that disable the car when drivers aren't paying attention. TKM |

Back on subject. Standards are useful and the world lacks standards. In North America front amber colored lights are most often used as DRL's and parking lights and turn signals and front marker lights, often from the same unit. In Europe amber is typically only used for flashing turn signals, and DRL's and front marker lights (be they called city lights or parking lights, etc.), are white. But North America mandates side reflectors and rear reflectors, amber in the front and red in the rear. This is not required or even permitted in many countries and I have even seen amber rear side reflectors in Italy. German manufactures are the worse in North America in having eliminated amber rear turn signals to make the vehicles look more American. BMW/Mini, VW/Audi just don't care about providing this safety feature to the drivers of North America. Honda is not far behind in this trend. The irony is that Chrysler is slowly adding this feature across its line here in North America. Richard. |

Passing isn't very safe because of your actions. Well, to be honest it's because of my reaction to your action. But your action almost mandates my reaction which puts the responsibility on your shoulders. (I'm talking about the moral responsibility since I'm not an expert in the legal field.) BTW, I wont look into my mirrors for the same reason I wont look into the sun. |

Most of the world requires or accepts ECE-compliant automotive lighting and prohibits USA-compliant equipment; the US prohibits ECE and requires USA. > In North America front amber colored lights are most often used as DRL's and parking lights and > turn signals and front marker lights, often from the same unit. Yes. > In Europe amber is typically only used for flashing turn signals, and DRL's and front marker lights > (be they called city lights or parking lights, etc.), are white. Yes, but there's a terminology problem here. What we are talking about in this thread as "city lights" or "parking lights" are properly called *front position lamps* in ECE regulations and "parking lamps" in USA regulations. There is another function, properly called "parking lamps" in ECE regulations. This is the left-side-only / right-side-only front and rear lighting that can be switched on by the driver, as called for in the German road code (StVZO) when the vehicle is parked in certain kinds of streets after dark. ECE "parking lamps" are generally required to be white to the front and red to the rear, but may in some configurations be amber. > But North America mandates side reflectors and rear reflectors, amber in the front and red in the > rear. This is not required or even permitted in many countries USA and ECE regulations both require red rear reflectors. USA regulations have required amber front and red rear sidemarker lights _and_ reflectors on all vehicles since 1/1/70. In addition to improving side conspicuity by displaying the presence, position and direction of vehicles circulating in traffic after dark, the sidemarker reflectors serve the same function as the ECE "parking lamps" (i.e., provide parked-vehicle conspicuity in dark narrow roads). The US method is better in this case, for it is passive -- no action required by the driver to switch on -- and it consumes no power. ECE regulations require sidemarker lights on vehicles over 6m long, and permit but don't require them on vehicles under 6m long. They are required to emit amber light, except that a vehicle's rearmost sidemarkers may emit red light if they are grouped, combined, or reciprocally incorporated with the taillamp, the rear end-outline marker lamp, the rear fog lamp, the brake lamp, or it is grouped or has part of the light emitting surface in common with the rear reflector. Most ECE-spec vehicles that have sidemarkers have amber front and rear ones. The new Citroën C6 has amber front and rear sidemarkers even though the rear ones are built into the rear lamp cluster (and therefore could legally emit red light). But, many vehicles which in their US-spec configurations create the red rear sidemarker function by means of a wraparound red lens providing a "side view" of the bulb, likewise have the same setup in their ECE-spec configurations. Many BMW and Mercedes models have such a setup. As for side retroreflectors: They are, as already mentioned, mandatory in the US on all vehicles. Amber front and intermediate, red rearmost. They are mandatory under ECE regulations on vehicles over 6m long, optional on vehicles under 6m long, and the ECE color requirement is amber, but the rearmost side retroreflector may be red if it is grouped or has part of the light emitting surface in common with the rear position lamp, the rear end-outline marker lamp, the rear fog lamp, the brake lamp or the red rearmost sidemarker lamp. Many vehicles which in their US-spec configurations have the red side retroreflector built into the side of the rear lamp cluster lens also have this configuration in their ECE models. Examples abound from BMW, Mercedes, Chrysler, Volvo and other makers. > German manufactures are the worse in North America in having eliminated amber rear turn signals > to make the vehicles look more American. BMW/Mini, VW/Audi just don't care about providing this > safety feature to the drivers of North America. I agree with you that amber rear turn signals are an utterly basic component of a proper automotive lighting system, and I agree with you that it's shameful to treat safety devices as stylistic toys, but having just returned the other day from a large automotive lighting technology congress in France, I can say you haven't got the whole story. I spoke with the BMW exterior lighting chief, and he told me they wanted to use the same type of amber rear signal on their US-market E90 3er as they use everywhere else in the world, but the US DOT objected. This type of "hidden" amber rear signal uses a clear bulb with a green plastic balloon over it, all behind a rose-red (dark pink) lens. The result is a lamp that looks red when off, but shines amber when on. It's subtractive color mixing. The technique has been in use for about 13 years or so -- no problem, such signals work fine and don't notably degrade with age or use. But, the DOT said the green plastic for the balloon was not on the list of approved plastic materials for use in car lights, and they kept saying "no!" or simply stalling and not answering at all regardless of how much test data BMW submitted. Finally DOT said "OK", but by then it was too late; in order to meet production schedules, BMW had to make an alternate choice for the US market. They could've gone to a plain amber lens, or a clear lens with amber bulb, but for whatever reason (probably related to tooling cost), the red lens was their emergency "Plan B". This is the same reason why the first-year Audi A8 had these green-ballon/pink-lens/amber-light rear turn signals, but subsequent years had red lenses: DOT bitched about the green balloons being made out of an unapproved plastic. The situation is different with Audi: On some of their present car designs, they couldn't have an amber rear turn signal without the red brake/tail lamps being too small to comply with US surface area requirements, so the only choices were to redesign the rear lamps entirely (larger - not approved by the stylists) or have a red rear turn signal for the North American market. This is the same reason why older BMW 5er wagons had red rear turn signals. Other Audi models have plenty of rear lamp area to have an amber turn signal, but as Audi's chief of exterior lighting explained, "if some of your vehicles have red and some have amber, this does not look like a coherent line of vehicles. I don't like red rear signals, but they're just as legal as amber in North America." I didn't get a chance to ask about the MINI's red rear signals; that's neither a materials nor a surface area problem. > Honda is not far behind in this trend. Honda, Toyota and Subaru are actually markedly *worse*, together with Ford, GM and Chrysler: All their models have rear lamp designs with ample area for amber rear signals, and they don't tend to use materials that DOT gets itchy about -- they use red signals in North America for specious "customer preference" reasons (have you ever been asked to vote?) or because red ones are cheaper to make and "show us the pile of dead bodies indicating that amber is better!". > The irony is that Chrysler is slowly adding this feature across its line here in North America. No, they aren't. They play with it, back and forth, red to amber and back to red, as a stylistic toy. The newest Jeeps all have red, after many years of using amber, for instance. Red ones would be almost marginally tolerable if they were all the combination brake/turn type, but immediately-adjacent, colorimetrically- and photometrically-identical separate red brake and turn lights duelling with each other make it very difficult to acquire the vehicle's signalling messages quickly and accurately in traffic. It's known that following drivers react significantly more quickly and accurately to a vehicles *brake* lamps if the vehicle's turn signals are amber rather than red, but nobody's bothered doing a study in actual traffic, so while all the regulators know red ones are dumb and amber ones are good, the automakers' lobbyists prevent legislating for amber rear signals in North America. "Show us the pile of dead bodies!" (the Ford guy actually said "It's the only light that flashes on the back of the car, why does it need to be a different color?".) DS |

> I don't get how BMW can be stupid enough to use the high beams as DRLs. Very simple: COST! High beam headlamps aren't frequently used, so there's less impact on the effective useful life of a device a driver might be unhappy with if it were to last a shorter time than he expected (ask any VW Beetle owner how he likes having to replace low beam headlamp bulbs every other month). Also, with high beam DRLs, there's no need to worry about turn signal intensity. > Turn signals, fog lights or low beams at a reduced voltage would have > been much better... Well, high beam DRLs don't work very well (too much intensity straight ahead, not enough intensity out to the sides), but fog lamps are not legal as DRLs in the US, only in Canada. Low beams don't make very good DRLs at all. If one is constrained to using only the lighting equipment on a non-DRL vehicle, without adding any new lighting devices, then the front turn signal DRL is definitely the best pick, all things considered. |
