Daytime Lights: Best Thing I Ever Did
For anyone on the fence about whether to add daytime lights to your commuter, I just want to say that mine have added a much, much better sense of security to my rides, both to and from work. People clearly see me now and treat me like a moving vehicle, rather than just another annoying tree-hugger who's not in a car.
Don't even worry so much about WHICH headlight and tail light you buy; just do it. |

Smart move. I've decided this year that I'd rather have it there whenever I want it, even on my road bike, than save a little weight.

Definitely helps on days when you are in and out of shadows. It's a good investment.
|
|
As a driver, there have been times when I have been "surprised" by a bike either in the shadows and/or wearing dark clothing. These days, most cars on the road have DRL (Daytime Running Lights). Motorists expect lights. So I got one.
Still doesn't help much when the driver is staring at their phone (had someone run me out of the crosswalk this AM), but does make things a little easier - especially around intersections) |
Part of my morning commute is on a quiet "country" road, heading directly into a blinding sun. When I drive this road at the hour I commute, I cannot see ANYTHING on the side of the road, let alone pedestrians or cyclists. So when I am one of those objects on the side of this road, I want to do everything I can to attract the attention of drivers. My ultra-bright yellow t-shirt just isn't enough these days, but a flashing red light always wakes people up.
|
Earlier this week I was sitting on the side of the road next to my house talking to a neighbor. I was on the bike. All the lights were running.
Another neighbor turned onto the street and yelled "Geesh...think your lights are bright enough? I saw you from way down the street!" All I could do was thank her for verifying how effective they were for me. (She wasn't being nasty. She s very nice. She was just surprised as how far away she would see the lights) |

Wait...I want to change my response.....

Mind blown. :D |
Been doing this(runing w/ lites on all the time) for about 10 years now.
I'll add another tip; have at least 2 front and 2 rear lights. :) |

If the weight of a tiny modern LED bike light is slowing anyone down, they should be using an old MagLight with 4 D cell batteries for light AND for better cardio.
Wait...I want to change my response..... It's ironic that the bike becomes heavier the more light you add. Mind blown. :D |
I'm a big fan as well.
There is such a thing as TOO bright a blinkie at night. Prob less so during the day. I just got some Bontrager Ion/Flare 200 lights that I like a lot because they change brightness automatically based on the light conditions. Also very small and light. |

Night time I'd run one blinking, one solid up front. Bunch of solids and one blinking on the back.
|
I had a guy pull up next to me in his truck on my ride today (on a lightly traveled country road) to tell me without my rear light (a Blackburn Dayblazer 65) he probably wouldn't have seen me. I guess being 6'4" on a bright yellow bike wearing a fairly colorful jersey isn't good enough haha.
He was quite nice, wished me a good ride before he pulled away. |
I've been doing this for about 10 years too, back when I was using a 165 lumen light and thinking it was bright. I still remember the guy who saw me before I saw him and waited for me to go by before opening his door.
|
So how many lights is too many? I have one 850-lumen headlight set to steady/pulse and one 150-lumen taillight set to a delayed blink. I feel like they are perfect. At what point do you think multiple lights blinking at various speeds becomes more of a (potentially dangerous) distraction than an eye-catcher?
|
I turned my commuter's generator-hub powered lights on 10 years ago, and have thought little about it since. I have other lights, front and rear, but the two lights are always on, rain or shine, day or night.
On my (daylight) commute home tonight, while I was approaching a stop sign, a car coming from my left turned right at high speed, crossing all four wheels into my lane. He saw me, and widened his wide swing and passed on my RIGHT! I don't know if my daytime running headlight helped him see me or not, but it surely didn't hurt. |

Daytime running lights probably won't hurt; but I'm not convinced they help - at least not in urban conditions where visual overload is already an issue.
That said, I have started using a rear blinkie on the premise that it makes me more visible from behind on bright days when I ride into deep shade.

Just my opinion, but as one who cycles and occasionally drives in visually complex urban conditions, I think in ambient lighting a bright pinpoint light. especially flashing, is conspicuous [incuding a rear blinkie].

Yawn. Over in the A&S forum a cyclist was hit in broad daylight with a flasher going. At very, very high speed. I am amazed they survived at all.
While nice, it is not essential that oncoming traffic see you, it is more important that trailing traffic see you, but it is even more important that you as a cyclist do not act unpredictably and force a motorist to accommodate your erratic actions. Because they may not, whether they 'see' you or not.

Obviously night time lights are a necessity, but I think calling day time lights a crapshoot is begging the question. Personally, I run daytime lights, that I don’t think are overly bright, and daytime oncoming drivers’ or cyclists’ eyes are pretty well accomodated to sunlight.
If you believe in dayttime lights (independent of the cost of lights since they are a nighttime necessity ayways), you win with possibly increased safety, you lose with perhaps battery wastage and increased incremental costs;if you don’t believe daytime lights, you lose by possibly diminished safety [in specific singular instances], but win by conservation of your battery life. However, incredibly bright lights are a losing proposition to oncoming traffic, though they win if they are alerted. So IMO, unreasonable use of lights is determined not by cost, but by inconvenience to oncoming vehicles

Many disputed safety practices, while maybe ineffective, are of themselves relatively harmless, e,g daytime lights, rear view mirror; perhaps less so, FRAP vs Take the Lane.… I like to consider the perceived risk:benefit ratio (based on my own experience, and/or advice of trustworthy others). There are three kinds of lies: lies, damned lies, and statistics. |

Thanks, I understand your correction, but in this instance, I will stick with empirical
"Empirical evidence is the information received by means of the senses, particularly by observation and documentation of patterns and behavior through experimentation. The term comes from the Greek word for experience, ἐμπειρία."

When it comes to safety issues of bicycling, I consider the Aphorisms of Hippocrates, Greek, so-called Father of Medicine: : Life is short, and art long, opportunity fleeting, experimentations perilous, and judgment difficult. The alternative, “experimental” methodology was previously described:

Roughly thats it, unless you were trained properly, in a controlled setting and tested in a validly designed and executed study. Then, if the results for a large enough group of people were taken in aggregate, anomalous factors accounted for properly, then those results would mean something more.

I happen to be in a scientific profession where strict adherence to properly controlled studies is the norm with the statistical parameter “P<.05” as the holy grail. Yet in my career I have seen well-accepted hypotheses fall by the wayside, or have encountered outliers to the data set.

Why couldn't you see the cyclist wearing brightly colored clothing with flashing lights on his bike?

I hope my daytime lights attract the attention of drivers so they know I'm there, but we all know that all too often "I didn't see him" is what they say because they weren't looking. So I would hope that a cop would ask the driver, "WHY didn't you see them? What were you looking at which made you not see them?"

Nonetheless, I think that any safety practice, including daytime (front and rear) lights, helmets, FRAP, even if unproved by studies, would be favorably considered by even the non-cyling public, including judges and juries. The driver got a year in jail. |
Jim, I have no idea what you are trying to say with embedded quote after embedded quote, but the one thing that jumped out at me as wrong is “While nice, it is not essential that oncoming traffic see you, it is more important that trailing traffic see you.” Oncoming turning and crossing traffic has very little time to react to a cyclist, so it is equally important to be visible from the front and the rear.
