LED bike lane laser tail light

[sk8norcal]

saw a guy with one,
he said he got it on ebay...

edit, probably a copy of this,

Unfortunately, only works if the car drivers are looking out the front window. Cool idea, but I question its effectivness on drivers in the USA.

[kfong]

Nice idea, but only useful if you use lasers with industrial outputs that can slice the cars if they get too close

Half price sale today, $18 shipped. I had to buy one.

Sounds like a good idea. I wonder if it actually helps in real life.

I saw a guy riding with one a few weeks ago, it seemed pretty cool. I definitely noticed, but I was pulling up on my bike. Not sure if everyone would see it, but it can't hurt right?

even cheaper ^^

[snellemin]

I've seen it. It works when it's really dark. Other than that, it's useless. A bright flasher works better.

I got a contractor lazer, bought cheap from an auction house.This sat on a stand & finds its own level , has a spinning mirror that spreads the red light 360". It has a speed control, from a slow flash to solid appearance & beam width control. 1000 foot range. Still had some juice in the battery, rotates, but no light. SO I got to check if its because of low voltage. Its 12 or more year old, need to remove battery rather than jury rig a charge or fire.

These used to bother my eyes on construction sites, that was a narrow beam for a drop ceiling grid. The wide beam should be useful, flashing red will get a ticket, narrow beam might get me run over, "didn't see the bike, blinded by this red light". Wide beam should lightup everthing at 100 meters.

Then I got me some road line powder, them reflector beads spread on the fresh paint. Figure out how to glue on outside bike surfaces without wasting it. Catch the truck at night when the crews are working, bring your own container, you may snag a liter or two. Wait till one guy is running the machine, then hit the powder guy when he returns for another pail of beads. The spray guy is the crew boss. Its happenin" now.

Thanks for the reminder by your post. Anyone know technical on the laser used in the device?

found one from hong kong 12$ shipping.. should be good for the trike..

[Ypedal]

took almost a month, but it arrived this morning ! ( taking pictures.. more in a bit )

Nice box ! ( magnetized lid ) .. but was shipped in a brown bubble envelope so.. the corner has the expected crunch..

..

Uhm...

1- Pis ?... Please..
Should say " Please remove 3x screws from back cover

2- Pis put 2pcs AAA battery and lid the bicycle light
Should say " Please use 2x AAA batteries and reinstall rear cover

3- 2 " Buttons " lol...

A and B are just as badly translated... if i was going to spend this much money and time to make a product, the least i would do is insure proper translation.. this is hilarious on such a nice packaging.. i'd expect this on a photocopied piece of paper badly folded .. as sold on ebay.. but wow.

Enviromental Material ! lmao...

2 buttonS .. . you have to cycle thru all the modes to turn it off.. should be a " Hold button to turn off " or something like that.

the LED's are pretty bright,,. and you can combine laser or either one by itself ( LED and LASER )

The mounting bracket has a quick-release lever so you can remove the light from the bike, leaving the bracket behind. slide rail type..

Now if the weather can clear up i can give it a test... this week is nothing but cold temps and rain.. argh.. and i'm on vacation ( so .. well.. even if the weather sucks.. i'm home enjoying life ! )

Now retrofit it with 2 10mW 632nm laser diodes

Hehe...

[BATFINK]

Just seen this on ebay - quality does look a little crude but are they a good idea, looks good to me.

[BATFINK]

Oh and could the LED's be replaced by some really bright Cree led's?

[cal3thousand]

I think there's a thread floating around here about those lights.

About the cree's ... anything can be retrofitted with the right knowledge. I don't think those things run a high enough voltage, out of the box. LiPo ftw

Hehe...

So.. i'm ordering one of these... seriously... but do i need a driver for it ?.. or does the " module " include all i need to simply apply proper voltage ?

I heard blinkies hypnotize the drunks and bring them right into you, and while the lines are cute they are too thin to be seen by motorists. A strong rearward facing red with clear facing down to light up the road all around the rear of the bike, just like millions of motorcycle lights have, is the way to go. They've been at it for decades, so why not follow their lead? While you're doing lights don't forget the brake lights and turn signals, so you can signal your intent to the drivers behind instead of leaving them guessing.

Like this:

using pretty old (80s?) Honda motorcycle lights (and an '85 Ford LTD headlight)

Vs typical bike lights:

using pretty bright LEDs.

Like this:

using pretty old (80s?) Honda motorcycle lights (and an '85 Ford LTD headlight)

And what is the power requirement for that setup? 50W, 75W or 100W?

[amberwolf]

With just the taillight and front markers it's 25.4W.

With headlight too (whcih is a highbeam cuz I can't find the other regular one), it's 86W.

With brakelight too, it's 105.1W. (that is as-pictured above)

With a signal going, it's 150.2W but that may be partly the surge current as the reading doesn't have time to stabilize before it turns the light off.

I find it acceptable, since this lighting makes a huge difference in how cars react to me on the road, even on this bike (even moreso on CrazyBike2).


If I were to do what I did on CrazyBike2 and replace the taillight bulb with the CFL, it'd be just as brigth as on full braking, all the time, with only a few percent of the power usage of the taillight. Then I'd use either a "3rd brake-light" bar like on CB2 or a separate LED motorcycle taillight for the brake light.

Same for the markers/signals, where on CB2 they are little LED MR16 units that Texaspyro sent me to play with, kinda shoved into the space inside the incandescent-lamp holders. (but I would have to build a bit of electronics for those, first to run an always-on stepped-down voltage to them for front markers, diode-or'd with the signal flasher, and second to build an electronic (non-thermal) flasher that would operate at the much much lower currents used).

Then I'd only have the huge power consumption of the headlight. But so far, I haven't found an optics solution for LEDs or CFLs that gives me the right (useful and safe) beam pattern for a headlight, so actual headlights are the only thing that really work for me.


DayGlo Avenger has a similar setup, except it's just a red LED motorcycle taillight, no white light for plate lighting, so it doesn't have nearly the "presence" these others do. I have been contemplating adding some white LED or CFL lighting underneath it so that it isn't visible from the rear (just like the others), only below.


CB2's is even more effective than either of these others, though, because the taillight is above the big white cargo pods and rear wheel, just behind the 'bent seat, so it lights up the whole back of the bike below the light, as well as the road around it.

[SamTexas]

With brakelight too, it's 105.1W. (that is as-pictured above)

That's about 20% less than my power requirement at 18mph on flat.
