Last updated 02-07-13




This is a flashing LED bicycle taillight with a twist: it also features a pair of laser line generators that project vivid red lines both port & starboard (left & right) of your rear tire!

The LEDs have three modes: all steady-on, all unison blink, and a back & forth "chaser" mode that I like to call, "Cylon mode" because the LEDs blink in a back & forth fashion that reminds me of the lights on the helmuts worn by Cylons on the old TV program, "Battlestar Galactica".


SIZE



To use this product, affix the bracket to your bicycle's seat post by unscrewing the large plastic standard screw with a medium flathead (standard) screwdriver until the strap is released. Wrap the strap & bracket ass'y around your seatpost, insert the strap into the slot provided for it on the bracket's body, and turn that screw clockwise until the strap is good & snug. Before finishing tightening it, be certain that the part of the bracket with the mounting shoe on it faces exactly rearward -- not forward or cocked at some funny angle that isn't truly lined up with your bike's back tire or fender.

Position the mounting shoe vertically and use the thumbscrew to tighten the mounting shoe to the desired position.

Slide the light itself onto the mounting shoe, and test it to be certain that the lasers run more-or-less parallel to your back tire.




To activate the LEDs in steady-on, press & release the button marked, "LED" on the unit.
Press & release it again to activate the LEDs in a unison blink mode (where they all blink on & off at the same time).
Press & release it again to activate the LEDs in a back & forth "chaser" mode that I like to call, "Cylon mode" because the LEDs blink in a back & forth fashion.
Press & release it again to neutralise them.

To activate the lasers, press & release the button marked, "LASER" on the unit.
Press & release it again to neutralise them.



To change the batteries, lift the Bicycle LED + Laser Taillight out of its mounting bracket and turn it upside-down.

Slide the battery door off in the direction of the arrow embossed into it (John Gastineau, that f***r was hard to remove!!! ), carry it to a bridge over deeper water (the Golden Gate Bridge would be ideal; however, the Juneau-Douglas Bridge would also suffice here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, remove the two used AAA cells from the compartment, and dispose of or recycle them as you see fit.

Place two new AAA cells into the battery compartment, orienting them so that their flat-ends (-) negatives face the springs for them in each chamber.

Slide the battery door back on, and place it back onto its mounting bracket.
Aren't you glad that you didn't throw that battery door over the side of the Juneau-Douglas Bridge now?


This is what the Juneau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.


And this is what the bridge looks like now.



The Bicycle LED + Laser Taillight is intended to be used as a bicycle taillight, not as a flashlight meant to be carried around, thrashed, trashed, and abused; I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash 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 scanner-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 inflict upon it punishments that I might inflict upon a flashlight.
So this section of the Bicycle LED + Laser Taillight's web page will be substantially more bare than this section of the web page on a page about a flashlight who's sole purpose in life is to be a flashlight.

Although I do not own or have access to a bicycle, I'm going to see if I can affix it to my scooter or electric wheelchair...in any case, it will be handled in a manner consistent with how the average consumer would handle it.

Image is not that great for two reasons:
1: Camera doesn't image red light all that well.
2: Light output isn't huge.

That kitty cat in this picture is Bear-Bear; he was simply curious as all cats are.

Laser power cannot be measured with the instruments at my disposal because their sensor size is way too small to encompass the entire laser beam emitted by this product.

That music you hear is zax from the Sega coin-op arcade video game, "Afterburner II" from 1987.
This product is not sound-sensitive; the zax may be ignored or even muted if it tees you off.
