My dogs Bling Bling Blinker safety light is plenty bright to see a quarter mile away when it's dark. And check out how small the LED's are.

I can't even see them with a normal magnifying
glass and need to use a 14x jewelers type.

The view in that circle is at about 10x
and the LED is the dot in the middle.


Here is the product.

Yep, LED's are getting amazing in brightness and low cost.
It's cool you brought this up as I came in to post an update on my search for an 'always on' motor powered front blinking light for the motorized bikes I build and sell.

With 3 batteries I assume 4.5VDC, easy to obtain for any Chinese motor's Aux power and you wouldn't even notice it.

Niterider is advertising a cordless headlight for $150 now that's claimed to put out 600 lumens! I've read that cheaper manufacturing ptrocesses have been discovered, so the lamps would be getting cheaper. This may be just the first of those.

I plan to get one someday. The older lights available now in that lumen range sold for around $400 last year.

Ya, I would think a good hundred of the LED's used in this thing could fit on the end of a pencil eraser easy. And the flash is almost to bright (or maybe harsh) even when the dogs far away.

I don't know how long the battery's will last either because none have died. And this is my third light I've bought in the last few years.

Since we are on the subject, I have been eyeballing this for my Jeep:

I was wondering if some of you guys that know about vehicle electrics and LEDs know of a cheaper option for me. I am just wanting something to light up the underside when I am wheeling at night so I can see where the tires are going.

Just a guess but it looks like the housing for those lights is whats expensive to me? Maybe you could just make a clear Plexiglas cover for something you like thats tough enough.

Electrical fittings come to mind.


And those LED's for replacing taillight bulbs.


I would think the hardest part (if it matters) would be finding LED's that produce light thats not to white.

If using multiple LEDs, then just mix a few yellows in with the whites. ..



As far as do-it-yourself LED rock lights on the cheap...

I just finished my first custom retro bicycle headlight and it is just flat awesome for ~$60.

The retro bicycle light was nothing, it originally came with 2 flashlight bulbs and ran on a pair of AA batteries.





I pulled the reflector with 3 high power CREE LED's that pump out over 3,800 Lumes from this flashlight:

http://www.tmart.com/TrustFire-CREE-XML-T6-5Modes-3800LM-LED-Flashlight-Electric-Torch_p125449.html



LEDs 3
Luminous Flux 3800 LM
5 Modes High-Mid-Low-Strobe-SOS
Light Color White
Body Color Black
Power Supply 2 x 18650 3.7V battery (not included)
Flashlight Life 100,000 hours
$49.

And fit it inside the original lamps reflector and managed to wedge in a pair of 3.7V Li-Ion batteries to make this.

This is the old style bullet with new flashlight head in it.



This in the same position turned on.



It completely washed out my cameras ability to see any other light than the bulbs.

To emphasize just how bright it is, it's mid-morning, I have sunlight coming into my shop from a window and big sliding glass door, and that ceiling light has a pair of 100W incandescent bulbs in it.



Yes, that is the beam above and brighter than the ceiling lamps in a lit room from 15' away!

Not bad for ~$60 including the Li-Ion batteries ehhh ;-}
