The LED Bike Light is a bike marker light that uses two phosphor white LEDs behind a common positive (magnifying) lens.
It is powered by two CR2032 lithium coin cells (that are included and already installed) and has three operational modes plus "off".
The LED Bike Light comes in a plastic body with a silicone rubber outer "shell" that gives it some degree of weather-resistance.
Press the top of the product and then release it to turn the LED Bike Light on in steady-on mode.
Do this again to change to fast blink mode with a flash rate of approximately 6Hz (6 flashes per second).
Do this again to change to slow flash mode with a flash rate of approx 3Hz (three flashes per second).
Finally, do this again to neutralise the LED Bike Light.
Just like it reads on the backs of many shampoo bottles, "lather, rinse, repeat". In other words, actuatimg the unit again turns the unit on in steady-on mode.
This product appears as though it were designed to fit on the horizontal portion of your bicycle's handlebars.
Since I do not own or have access to a bike, I cannot show you with photographs.
To change the batteries in the LED Bike Light, "peel away" the black silicone rubber outer casing from the hard plastic light itself; peel it away enough to expose the bottom of the unit.
You'll see a circular white plastic "lid"; lift it straight off and set it aside.
Turn the unit rightside-up and gently "bang" it against the surface that you're changing the batteries on (a table, a desk, etc.) until the two dead batteries fall out.
Dispose of or recycle the dead batteries as you see fit.
Insert two new CR2032 lithium coin cells into the unit; orienting each cell so that its button-end (-) negative goes in first.
Place the white "lid" back on, orienting it so that the tab on one side of it faces the front of the light.
Gently pull the black silicone outer casing back in place, and you're done.
I don't expect anybody to be able to execute a successful battery change in total darkness, so please try to change the batteries in the daylight hours or indoors under artificial light.
THIS PROCESS SEEMS A BIT FIDDLY; THIS IS GOING TO DETRACT FROM ITS RATING!
This is a bicycle light in a plastic body, not a flashlight in a metal body that's meant to be bashed, thrashed, trashed, and abused, so I won't bash it against a steel rod or against the concrete floor of a porch, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a large claw hammer in order to smash it open to check it for candiosity, fire it from the cannoñata (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout, with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; and the cannoñata is only used to shoot piñatas to piñata parties away from picturesque Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight in a metal or sturdier plastic body might have to have performed on it. So this section of the web page will be a bit more bare than this section of the web page on a page about a flashlight that was born to be a flashlight and nothing but a flashlight.
The plastic window has a magnifying configuration and also serves to protect the LEDs and give a measure of water-resistance to the product as a whole.
There is no environmental protection (such as O-rings or gaskets) visible, so water-resistance is going to be minimal at best -- though that black silicone rubber outer covering will offer valuable weather-resistance -- that is, a few raindrops or snowflakes won't do it in, but please keep it out of puddles, water-filled ditches, snowbanks, wall-mounted porcelain or stainless steel urenals, pet water bowls, toliets, bathtubs, fishtanks, sinks, or other places where water or water-like liquids might be found.
If some asshaberdasher "pyst" on it or squirted a Massengill brand post-menstrual disposable douche or a Fleet brand phospho-soda disposable enema at it and hit their target, disassemble it as you would for a battery change, rinse all of the parts in fresh water, and let it dry for a day or so before reassembling and using it again and you ought to be OK.
The front of the packaging materials indicated that the product has two white *AND* two red LEDs; but the red LEDs are not present at all in this particular unit.

Spectrographic analysis of the LEDs in this bicycle light.
Spectrographic analysis of the LEDs in this bicycle light; spectrometer's response narrowed to a band between 430 and 450nm to pinpoint native emission peak wavelength, which is 443.760nm.
Spectrographic analysis of the LEDs in this bicycle light; spectrometer's response narrowed to a band between 540 and 560nm to pinpoint phosphor emission peak wavelength, which is 551.890nm.

A beam cross-sectional analysis would normally appear here, but the ProMetric System
that I used for that test was destroyed by lightning in mid-July 2013.
In this video, you'll see the LED Bike Light displaying its operational modes.
TEST NOTES:
Test unit was purchased at the Happy Mini Mart in Fresno CA. USA on 07-02-21.
UPDATE 00-00-00:
PROS:
Soft silicone outer covering gives the unit weather-resistance
NEUTRAL:
Not nearly bright enough to use as a headlight -- "marker light" would be more appropriate here.
Product is going to lose a bit off its rating because of this.
CONS:
Battery changing seems a bit on the fiddly side (this is what nocked the most stars off of its rating!)
