I need some super LED's where do I find them?

Reminds me of...me No, I'm sure of it. I hate him
Okay so for my sr500 build I want to build a tail light that goes under the rear tail section, so it will not be directly visible from behind.
With this in mind I know that the commercially available tail lights are just not going to be bright enough to do me any good (i have a bunch sitting around and they aren't even close)

What I am thinking is that I want some 3 watt LED's like used in offroad lights, they are insanely bright. I think 4-6 of those should give me enough light to light up the whole ass end of the bike.

My problem is I can't seem to find any?
Does anyone know where to get them? I'm thinking of buying a cheap light and tearing it apart, but I'd rather be able to buy the components.

This is what I am talking about:

I'm not sure how shining a light on your tire and shocks will serve as a good brake light. I don't know what you are planning to do as far as a rear fender goes, but maybe you could use some kind of reflective surface under your tail to spread the light out. Work it in to act as your fender. Or just a somewhat reflective finish on a fender would suffice. Like a white or chrome or bare clear coated fender.
 
I knew I'd get some criticism here!

The plan is to run a small running light on the swingarm. The brake light will be under the seat parallel to the seat/frame. When the brakes are hit the brake light will light up the whole rear end of the bike, which to me is a whole lot more eye catching then a small tail light.

To put it in perspective, average headlight for a bike is somewhere around 700 lumens. The ass end of my sr will light up with 1400 lumens.
Hard to miss.

I just found and bought this one ebay:

I will be modifying the housing somewhat and swapping over to a red lense.
 
WHY?
it wont do shit in the daytime ;D you need a bright light pointed right at the vehiculls behind you,.

At least I answered your question before implying you are an idiot.

And for that I thank you :D

I'm not worried about it, if it doesn't work or isn't noticeable I'll just redo it.
I have a feeling its going to work out really well though.
 
I agree. I think it will be hard to see on a sunny day. I do think you could get away with an indirect one like I mentioned as long as the surface is reflective enough.

You're probably right, we will have to see then won't we?
In the location it's going I think it will be visible while braking, but I won't know for sure until I ride it and see.

there is no probably about it unless you have a light pointed pretty darn directly towards behind you, it wont be visible for shit in daylight
thinking stuff up when drunk is fun i'll grant you that !

And not reading posts is even more fun ;)

In my reply to flug I said that the light will be mounted parallel to the road, pointed directly behind me. at ride height it will be concealed by the seat, but when braking when the weight shifts to the front my money is on it being visible.
But like I said you may be right 8) And if you are I'll buy ya a beer and swap the lights out ;D

i dunno, have it drop down outta the tail when you put on the brake ,then back up after you lift...
could eesily be done with a RC model servo motor ?
or just a shutter in the tail
 
Ooooooooo, intriguing. May check with Matt, but I think if you give the input channel a constant +5V, the servo will go to it's full + position, and likewise, -5V, to it's full negative position. One could probably figure out a simple voltage splitting circuit to work off of the 12V system.

You can get decent metal gear servos pretty cheap (around $10).

If it turns out you need a microcontroller to feed the servo the pulse-width modulated signal, you can also get really small ones pretty cheap ($7.95 - http://www.adafruit.com/products/1501). Couple guys on here including Matt and myself that can program them for you.

You could attach the back of the light to a hinge and then attach a control arm near the face of the light.
 
i think something like this servo operated with a similarly madmaxmechanicalsteampunkish looking tailpiece
