As for mounts, this mount is very simple but works well. Now, that's probably not going to work for use on a *** (unless you want the light to shine sideways), but there's a lot of other mounts that might work too.
I recently picked up the new ALB-10 flashlight mount from Fenix, and after some use can say that it's the best flashlight mount I've ever used. It's dead solid, adjustable side to side so you can get your light centered to your liking, quick release, and completely jiggle free. It's a winner.
Flashlights are really benevolent for any situation. Choosing an appropriate flashlight is important.
After browsing the forum(s) and the last couple pages of this thread, here's what I decided. I'll give a short review once I've had a chance to use them a few times. Front and Rear for under $36...
Note they are both in the US, as I didn't want to wait for them to come from China or Hong Kong.

That said, even if it's really "a mere" 1000 lumens, that's sounds good for the price.
I've seen several of the "laser bike lane" lights and have never been impressed ...
We'll see how your review turns out.
Quality wise it is way better than expected. The only thing that looks cheap to me is the battery holder.
Brightness wise, well this is a very bright light! About 3 years ago I bought a nice branded $300 HID light. It was about 13 watts and rated at 750 lumens. I loved it because it was a lot brighter than my older 10watt halogen light but it only lasted me 2 seasons. I was fairly bummed when it quit working. I was looking for a replacement bulb and realized I can buy a whole new light for cheaper. Not surprisingly lighting technology had come a long way. Given the battery was also 3 years old I decided to by a new one instead, but wasn't wanting to pay another $300...
So I came to BF and started researching lighting. It was fairly obvious LED and battery technology had surpassed the old lighting I was used to. I always loved the newer LED flashlights anyway.
Sorry, getting long winded. I'll get back to the point. Brightness wise, it's as bright on medium as my HID is on high. I used it on medium in pitch black dark but I feel low would have been fine. Medium seems twice as bright as low and high seems twice as bright as medium.
Only question now is how long it will last. If it lasts only 1 year it will be well worth it. I'll just buy another one next season lol...
I just ordered this Metro 360 & Hotshot 2W Combo from ebay (CygoLite Bicycle Metro 360 Hotshot 2 Watt USB Rechargeable Combo Set Rear Front | eBay). Not quite under $50, but it comes with the Hotshot rear flasher, and was under $70 with free shipping. The rack mount wasn't included, so if the one I have now isn't compatible I'll buy it from either cygolight spare parts, the ebay vendor (says it'll be available by the end of the week), or rig something up like I talk about in this other post: USB rear light that mounts on rear rack.
I wanted something I didn't need to worry about breaking, buying extra lenses for, and that didn't have an external battery pack. mtbr and bike light database have some beam-shot comparisons that make deciding easier. I'll let you know how it works out.
