A more cheerful reflection on Autumnal cycling.


Along with cooler weather, Autumn brings other changes. For example, it's darker longer.

Bicycle/bicyclist illumination is an often misunderstood topic. The government's Consumer Product Safety Commission's (CPSC) requirements for bicycles are laughable. The side-visible spoke reflectors are useless, and the front and rear reflectors are not much better. I do happen to like the pedal reflectors bikes are supposed to come with, but that are too often deleted at delivery. The up-and-down pattern the pedal reflectors make is surprisingly visible to an overtaking motorists, and always communicates to me that there is a cyclist ahead (long before my headlights illuminate the rider). Most higher-end pedals lack these reflectors. That's a bad thing.

Headlights serve two purposes. First, they SHOULD illuminate the road in front of you (some are so pathetically powered that they're doing good to even illuminate your front tire), and the speed you ride plays an important factor here. In darkness, I like my headlight to illuminate the road for two seconds ahead of me: one second to recognize the open manhole, another second to maneuver my escape. The faster I ride, the more power I require. I'm needing less power now than I used to.

Secondly, they tell people you're coming. Back in the very early 1980s, when I was young and stupid (as opposed to now being old and dumb), I was on an autumnal pre-dawn ride in East Dallas (commuting back to my house from my girlfriend's house, I believe), wearing blue jeans, a navy turtleneck sweater and a watch cap. I passed through an unlit, tree-covered residential intersection heading south (Alderson at Llano, perhaps), when another cyclist going east came out of nowhere. Both of us were moving pretty fast, and we JUST missed each other. Neither of us had any lights. We were like Ninja cyclists in the dark, and we darn near took each other out. We were lucky (if you believe in luck).

So if the first purpose of a headlamp is to illuminate your path, the equally important second purpose of a bicycle headlight is to let others know you are coming their direction.

But I believe that reflectors and reflectorized accessories and clothing are even more important than head lights and tail lights. A good S.A.E. (Society of Automotive Engineers) approved reflector sends more light back to a following car than does all but the most expensive bicycle lighting. The picture of two of my bikes above shows rear led blinky lamps, CPSC approved reflectors, reflective material on bags, and S.A.E. reflectors from the auto parts store. The best one of the bunch is the 4" diameter reflector I've attached to the rack on the bike on the left.

With the exception of one blinky light, all of the lights and reflectors on these bikes have been attached with zip ties and plumber's straps. For some bizarre reason, the bicycle industry is moving away from the universal mouthing brackets they use to use for rear lights and reflectors to new styles that aren't very adaptable. Plus, just try and find a big reflector at a bike shop.

(Note: As is mentioned in the Comments Section below, the reflectors appear to be amber, they are all red, with the exception of the white on the panniers. The flash was reflected back with such intensity the camera was fooled.)

When I ride at dark, I also wear a safety lime-green mesh vest with wide stripes of 3M reflective tape. I am visible to both overtaking and approaching motorists, and with my helmet and vest, I look like a construction worker in the roadway, which is a bonus. Why is that good? Because the motorist's brain will issue an alert to be prepared for road construction. PsyOps is a cyclist's friend.

You don't need to be afraid of the dark when riding your bicycle, and you don't need to spend $500 for lighting, either (although if you can, that's cool!). You can easily make sure you can both see and can be seen.

Please do it.

Good reminders, PM. More importantly, good advice to those who are new to vehicular cycling at night.

A few comments of my own...

Reminder:
This Sunday we return to Standard Time. As such, there will be an hour more of light in the morning and an hour less of light in the evening.

As we continue into winter, there will be a few minutes less daylight in each of the morning an evening commutes. The evening ride will lose more light than the morning until early January, when both will slowly gain illumination (though the morning a bit slower than the evening).

Keep all of this in mind as batteries are recharged and be sure to carry spares if your ride extends (or begins) too far into darkness.

One nit to pick, PM.
you write:
"Secondly, they tell people your coming."

The proper term to use is the contraction "you're" - as in "they tell people you are coming."

Herman, you caught me in edit-mode. I can't proof read for shat in the typing box, but must see it posted (I have the same problem with printed material). I believe the correction had already been made as you were proofing. ;-)

So... who wants to talk about hub-dynamos? Helmet-mounted light?

What do others think of blinking rear lights? You want to get a driver's attention but not to distract or annoy them.

I really just left off the preposition "of"... as in "They tell people of your coming." ;-)

Nice article, securely mounted lights and reflectors is also key.

AndrewP at Orlando Commuter has written a smart, informative article on a hub dynamo lighting system.

One point to add: at least one of those items in the rear is required to be RED by Texas law. Three inch amber reflectors are the brightest and avoid problems with colorblind people. Blinkys draw attention, but something's got to be RED.

Anybody knows what "the department" approves?

PM Summer said...

Steve, good reminder. In my case, the 4" roundie IS red. It reflects so much light back, the camera reads it as amber.

The blinkie it's mounted with is red, also. The lens is clear, but the three LEDs are indeed red.

Years ago, I used to have an amber 4" roundie on a wire that stuck out 18" from the left hub. I thought Forester told me to do that, but I can't find any reference now to support that.


As for the "department", it wasn't too many years ago that an oficer in Dallas was writing tickets to cyclists for riding the wrong way when they were riding with traffic, and for not having a head light at 2 PM. In other words, they'll do what they want.

There's a recently deleted post in cyberspace where I vent my frustration with the "department".
