Directional signal lights on bicycles?(6 posts)

Continuing w/ the bicycle as vehicle thread, why doesn't anyone make a set of directional signals for bicycles? Motorcyles are required to have brake lights, directional arrow lights, etc. in the daytime. If bicycles had them on the road, maybe drivers would think they're more like vehicles...

Also found an interesting report while searching for this:
It's a breakdown of cycling accidents from 1983 in the Boston area. There are a couple of interesting statistics in this report. Too bad they don't have anything more updated.

How 'bout some streamers for the bar-ends, and maybe a little horn with a rubber ball, while you're at it???

As I noticed on Sunday when out riding when a lorry nearly wiped out a motorcycle from behind, with a following low winter sun you can see nothing of the rear lights on (even a) motor bike, let alone a cycle.

Far more difficult to miss a good clear arm signal, and people wouldn't use both, so dangerous IMHO.

Bicycles are smaller than motorcyles too. I hear similiar complaints from motorcylist coworkers though.
"cars can't see me"
"cars cut me off"
"car nearly sideswiped me"

And you also see motorcyles weave through traffic between lanes when traffic gets bad (which ticks car drivers off). I just thought it was interesting that motorcycles are required to have signals and brake lights. They do get treated more like vehicles than bicyles though. The similiarities are interesting. Maybe it should be a "what do you like about the way motorcylists are treated vs. cyclists?" thread.

Directional lights are not legally recognized on bicycles in most jurisdictions, and for good reason.

Motorcycles are already narrow enough that approaching drivers can have difficulty distinguishing which side a turn signal is on. A bicycle would need a bar two or three feet wide to hold the signals far enough apart to make them at all useful at a distance.

Motorcycles have electrical systems that support bright blinking and steady lights. A bicycle would need to have quite a heavy battery to power lights that were usefully bright.

If you want to make your turn signals more visible, add reflective trim to your cycling gloves. I use silver reflective cloth trim on the backs of my gloves, and noticed an immediate improvement in the behavior of overtaking motorists when I signal left turns -- they no logner attempt to swerve around me on the left, but either wiat behind me or pass on the right.
