The Bicycle Head Light is a bike marker light that uses five phosphor white LEDs behind individual positive (magnifying) lenses .
It is powered by three AAA cells and has three operational modes plus "off".
The Bicycle Head Light comes in a plastic body.
Press the white button on the top of the product until you feel it click and then release it to turn the Bicycle Head Light on in steady-on mode.
Do this again to change to blink mode with a flash rate of approximately 3Hz (3 flashes per second).
Do this again to change to double blink mode (where the LEDs perform a quick double-flash) with a flash rate of approx 2Hz (two flashes per second).
Finally, do this again to neutralise the Bicycle Head 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.
To change the batteries in the Bicycle Head Light, locate the protruding button on the rear of the unit. Press & hold it in, and while holding it in, use your other hand to lift the two case halves away from one another by the rear of the unit. If you did this correctly, this is what you should see:
If necessary, remove and dispose of or recyle the AAA cells from the unit.
Install three new AAA cells, orienting them according to the polarity legends embossed into the bottom of each compartment. There are no traditional springs, so you indeed have to do it this way.
Press each cell firmly into its compartment, and close the case halves until they emit a fairly loud click.
There, done with that, fun yeah!!!
Nothing comes off the light; that's why I did not advise you to flush something away and then rather emphatically tell you not to.
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 Quickie Pulse 6 motorised wheelchair, stomp on it, viciously huck it at one of those wall-mounted porcelain urenals to see if it shatters and shoots little pieces everywhere (the bike light, not the urenal! ), use a medium sledgehammer 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 magnifying lenses moulded into it and positioned in front of each LED.
In my testing however, this window tends to pop off and go flying by doing nothing more than turning the light on.
There is no environmental protection (such as O-rings or gaskets) visible, so water-resistance is going to be minimal at best -- 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.
A small amount of rain or snow should not kill it, however.
If a snake did a wee on it or if some total and complete asshaberdasher squirted a Massengill brand post-menstrual disposable douche or a Fleet brand phospho-soda disposable enema at it and hit their target or they got really angry at it for some reason and "pyst" all over it or if the Bicycle Head Light fell off your bicyle and somehow found its way under the leaking radiator of a parked car (and the car's owner uses Prestone or other brand of antifreeze), 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.

With the lens assembly removed, it measures 120,700mcd on the same meter.
The "stripes" are because this product uses PWM (Pulse Width Modulation) where the light rapidly flashes instead of being true steady-on.

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 440 and 460nm to pinpoint native emission peak wavelength, which is 447.650nm.

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 Bicycle Head Light displaying its operational modes.
TEST NOTES:
Test unit was purchased at the Happy Mini Mart in Fresno CA. USA on 07-01-21.
UPDATE 00-00-00:
PROS:
Can easily be disengaged from your bike to use as a handheld flashlight (torch)
Uses batteries that are common and relatively inexpen$ive
NEUTRAL:
CONS:
Not nearly bright enough to be used as a true bicycle headlight
Lens pops off quite readily -- just turning the silly thing on frequently causes the lens to pop off & go flying!
