I'm finding this thread interesting and useful--so far it's made me think about this subject in a couple of ways that I haven't really looked at too deeply before. First, I'd like to say that it shouldn't be--and isn't--a question of
". . . which is more effective lights vs. Hi-Viz for being seen by left turners,"
. . . because it's not H-V
versus lights or anything else. Lights help. H-V helps. Add 'em up and it helps more. If you want max visibility, you'll do everything you can, right? And not to pick on any one post, but Z'sdad also said this:
We look for bikes because we are interested. We see the shape, colors, lights and gear because we are interested.
I would like to see a study using cagers that don't ride and don't know a rider. Of course this is my VHO.
I agree, but it didn't stop l
this from happening to me a couple of weeks ago. I ride, and I was riding when I almost pulled out in front of an approaching scooter. You have to be aware of them, but you have to SEE them too, and this one just didn't show up very well in those circumstances. As I said in my post, it would have helped if she'd had better front end lighting. Or been weaving a bit, as was mentioned earlier.
OTOH, lights aren't always enough either. I have lots--3 sets of Hyperlites on the back end, a couple strips of stick-on LEDs, a very bright reflective strip all around my top case and side case reflectors too, but in the daytime, none of that makes a really huge difference. Night, yes. Day, not so much. Look at both pics Tom posted below.
I think lights are much more effective than Hi-Viz clothing. especially widely spaced lighting that gives motorists a wide enough target to detect motion and closure. Individual headlights, and even the FJR twin lights don't give this width. The bikes in the picture below show how a difference of 100 feet makes a huge difference in the visible target width..That is Sacramento Mike in front, Old Michael in the rear.
Compared to standard lighting:
The lit-up bikes in the top picture really jump out--and this picture doesn't even do the aux lights justice, since in person they show up WAY better than the headlights do. In the pic, they' hardly seem brighter at all. But if you compare the 3rd bike (OM) in the top picture to the bikes in the second picture (in full sun), the stock headlights show up much better. So I guess lights show up better in the dark than in the daylight. Not much of a surprise.
If there was one more picture that showed the LED-equipped bikes in full sun, they'd show up better than the ones without LEDs--at least they would if the pictures really showed what you'd see if you were approaching from the other direction. But it's pretty easy to imagine how the riders in any of these pictures would look with good High-Viz gear and helmets. The riders in those gray and silver outfits in the second pic, especially, would be SO much more visible in good bright colors.
Anyway, and finally getting back to the question raised in post no. 1--What About Hi-Viz Gear? Well, I like my gray Olympia Airglide jacket a lot. Also my black CyclePort gear that I use in the more temperate times of year, and the warm, black leather riding jacket I use in the coldest weather we get around here. I don't want to abandon any of them for a different jacket in Hi-Viz. Might replace one with H-V if it ever needs replacing, but not yet.
Tom's statement that "lights are much more effective than Hi-Viz clothing" is open to debate, but I don't think it's debatable that they BOTH help. So the answer for me is that I'm now looking for a good bright mesh vest with bright reflective strips all around to wear over the jackets I have--day
and night. And keep my lights shining too. Looks like the best solution for me.
