The Shun X1 SAFEGUARD All-Purpose Bike Warning Light is a bike taillight that uses three red and two green LEDs behind individual positive (magnifying) lenses.
It is powered by two AA cells (that you furnish yourself) and has seven operational modes plus "off".
The Shun X1 SAFEGUARD All-Purpose Bike Warning Light comes in a plastic body, and is weather-resistant but NOT submersible to ANY depth.
Feed the Shun X1 SAFEGUARD All-Purpose Bike Warning Light two AA cells first (see directly below), and THEN you'll be ready to rock.
Press the white button on the back and then release it to turn the Shun X1 SAFEGUARD All-Purpose Bike Warning Light on in steady-on mode.
Do this again to change to fast blink mode with a flash rate of approximately 10Hz (10 flashes per second).
Do this again to change to slow flash mode with a flash rate of approx 2Hz (two flashes per second).
Do this again to change to change to a mode where the LEDs flash sequentially left-to-right.
Do this again to change to change to a mode where the LEDs flash sequentially right to left.
Do this again to change to change to a mode where the LEDs flash sequentially left-to-right at a much greater speed than before.
Do this again to change to change to a mode where the LEDs flash sequentially left-to-right and then back from right-to-left (I call this the Cylon effect).
Finally, do this again to neutralise the Shun X1 SAFEGUARD All-Purpose Bike Warning 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 Shun X1 SAFEGUARD All-Purpose Bike Warning Light, hold onto the white bottom half with one hand, and pry the top off from the side with what appears to be a latch. Use a dull knife such as a butterknife if necessary. Tip the red piece out as well (only if necessary; it may well stay inside the upper half of the light) while you're at it.
THIS PROCESS SEEMS A BIT FIDDLY; THIS IS GOING TO DETRACT FROM ITS RATING!
Carry them to the top of the basement stairs, and kick it down into the basement crawling with thousands of hungry, hungry silverfish that have to go poddy so that they all sniff & snuffle at the damn things, find that they smell like poo, and decide to pass micturition on them in unison...O WAIT!!! YOU'LL NEED THOSE!!! So just set them aside instead.
If necessary, remove and dispose of or recycle the two used AA cells from their compartments.
Install two new AA cells, orienting them as directed by the polarity indicators embossed in the bottom of each compartment (there are no traditional springs in this unit). With AA cells, their flat-ends are always (-) negative.
Once you have each cell partway into its compartment, you may need to press it fairly firmly to get the other end of the cell to go down all the way and snap into place.
Lay the red thing over the LEDs (if it fell out of the upper half of the light anyway), and then place the upper half over the lower half of the light, squeezing them together until the parts are flush with one another.
Aren't you glad that you didn't kick that upper half and the red thing down the stairs to all of those hungry silverfish with full bladders now?
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.
Th positive (magnifying) lenses in front of each LED are moulded into the plastic window which 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. 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 other liquids might be found.
Does this evaluation look an awful lot like the one that I made for this product?
Thought that you'd say so.
That's because they're optically and electrically very similar; the visible differences being the color of the LEDs,the size (this one's somewhat longer), and the orientation of the unit when clipped to something (this one clips so that it is horizontal; the other one clips so that it is oriented vertically).

Spectrographic analysis of the green LEDs in this bicycle light.
That "hump" in the red is from the red LEDs and was unavoidable.
Spectrographic analysis of the green LEDs in this bicycle light; spectrometer's response narrowed to a band between 510nm and 540nm to pinpoint emission peak wavelength, which is 519.950nm.

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.
