I didn't see it either so it's not just you. Ask them. I'd guess they aren't carrying the taillight package since most folks buy the headlight if they buy the battery/charger. It's a big battery pack for just a taillight, IMO.

That's the taillight only. I thought the OP wanted the whole enchilada - taillight, battery pack and charger in one box.

Iowegian is correct, I was looking for the whole kit. I did email them asking about the light kit

I saw that kit which include light, old style battery and charger for $55. Last time I saw that was on Monday the 21st. It seem indeed they took it out of their listing. It was a good value kit since the new battery are almost the same price as the whole kit with the old battery. Perhaps they were trying to sell out the stock of the old battery with that kit???? Who knows.

I just got home and read my emails, they wrote me back and told me that they were out of stock for now and that is why they are not listed now. They didn't say if they planned on getting any more in the future, just told me they had the light by itself if I was interested.

That's I'm thinking. That's why they include a Y-cable with it. I've just ordered two front lights and two rear lights for my kommuter My old Macicshine headlight will go on my helmet Overkill? You bet! Ha ha ha haaaaaa......

Naw, no such thing as Overkill

Better too much than too little. I'm running 2 PBSF and a MS tail light in the back. For my front, I have a MS 900(600 lumen) and a MG P rocket SST 50(800 lumen) on my handle bar. Also.....I have a MG X Thrower SST 50 (800 lumen) on my helmet. Total front light lumen: 2200 lumen, throwing more photon than a Klingon battleship

Why? Honestly I seldom run them all on high at once. However I do run them all on high when I ride through this shopping mall parking lot early in the morning. It's usually empty with no cars and kinda spooky because the mall conserve energy and have all those lights in that section turned off. Last thing I need is to get my bike jacked, so I light up the lot flooding the area with photon until I reach the main road.

I received my MS tailights yesterday. They have have pretty annoying design flaw: their position is not vertically adjustable if mounted on the seatpost. Its mount is rigid like the headlight's so it just moves around the seatpost left and right, but not up and down - that means it's pointing downwards. I mounted it on the rack, but that's like a foot lower.

Yes, I've posted on that. I have two cheap solutions. The first is a 5 minute DIY copy of the Dinotte taillight mount made from some plastic pipe using a saw and a heat gun.

The next works if you've got a sprung saddle


There are other solutions that involve various ways of attaching 3/4" PVC to a bike frame, rack, rack trunk or various other contraptions.

I just got one of those tail-lights (and the front). I wasn't able to buy it as a kit , so I ordered them individually (they all came together anyway.)

I'm not as handy with the DIY mounts, so I do wish they had some sort of clamp mount for it. I've got the tail-light O-ring mounted to my seatpost which seems to work fine, but it is true that it points a bit downwards as a result and isn't adjustable.

The light itself is awesome. Great blinking patterns that change up, and several times brigher than a PBSF. Great for dusk!

When it's dark enough to need your own to-see lighting though, a PBSF or Mars 3.0 with fresh batteries is pretty impressive - I've been passing commuters and night riders here in Norcal in the early mornings who use these, and I'm always impressed with how incredibly bright they look to me. (I use both of them myself!) But with the MS tail-light, NOBODY will miss you from rear approach. I like that safety factor since I'm on roads where cars routinely drive 50-55 most of the way.

Bummer - did geoman figure out people were buying tail light kits with separate "head light" only?

I did it twice and got both head light and tail light = charger and battery for $10 more then a head light only system

pretty sad mount photos - all you have to do is - use tape to "build" a "wedge" to make the seat post "seem" vertical. sheeesh...

Please further enlighten us - I'm looking for a way do put in a wedge that doesn't interfere with the quick on/off of the O-ring and won't break off by accident.

Yes, but the bottom photo is what I use - If I put a light on the seat post, I can't use a rack trunk or put anything at all on top of the rack.

Also, I don't really consider a balled up wad of tape to be a very stable or long term solution. I've never had something like that stay put properly. I ride 8 miles a day over gravel roads and any dodgy solution like that always winds up pointing at the ground or sky at the end of the ride.

I'm actually thinking that I'm going to build a PVC mount to put the light a few inches behind the rack, along with my truck reflector that's back there.

I built a seat post bracket for my MS taillight a few months back, but I since added rear baskets to my bikes, so I nixed the taillight bracket, bolted the MS taillight to the back of the basket after removing it's curved mounting bracket, rubber grommet, and then I water proofed the holes on the taillight's rear surface with silicone.

Mounting on the rack works out for me. Also, I don't like the mode selector ring. I'd much rather have a button, or at least make the ring click. As it is it's pretty annoying. Plus it's hard to operate with wet hands.

The new 900 headlights also have lower quality clickies that the old one, they're much harder to press.

Yeah, the ring is a pain in the butt. I like to be able to reach behind me and change modes without looking. Yesterday I realized after 1/2 mile that I'd forgotten to turn the light on. I just gave it a full turn and hoped for the best. I'd rather have a button.

There is also some inconsistency with the pressure force of rotating the ring. I got two taillight. The first one is easily turnable. A little to easy as a matter of fact and can get bumped into the next mode. The other light takes a lot more force where it's too much.

I asked GeoManGear if they planned on getting more of these and here is there reply

"Sorry, it could be more than a month, China is going on an 8 day holiday and we were able to get our headlights produced before their holiday begins but all other items are on backorder"

I figure I'll wait til they get them in to place an order.

did you get the battery with the back light? They still have just the lights for sale but they don't have the light and battery set to sell is what they told me.

I hear you. My second tai light has a lot more resistance as well.

I just concluded a dual tail light blinker test for run rime - and if you choose the alternate/ring pulse mode you can run two lights well over six hours. But this was using 6xAA - a Lithium battery would last even longer. I'm going to test the "long pulse" mode next.
