Hi Tremor, I happen to also be looking at different LED riding lights, actually looked at PIAA amongst many others. I'm in the market for a few different riding lights for several bikes at the same time.
- XT1200Z / S10
- XVS1100AC
- CFMoto Jetmax maxi scooter
Background;
I've upgraded my Dragstar Classic 1100 from a halogen to HID headlight conversion over a year ago. However I've wanted something to make the bike stand out. I've bought the OEM Yamaha driving lamps from an online dealer in the USA along with loads of other OEM accessories two years ago. The only item I'd ordered and paid for at the time that didn't arrive (USA-China) was the driving lamps mounting bracket (signal/turn/indicator lamp and driving lamp bracket conversion kit) to go with the OEM driving lamps (halogen) and the OEM front screen - the bracket was on backorder. The dealer I'd ordered from went bust and I never did get the mounting bracket nor a refund, and all emails went unanswered. The dealers website business was bought by another dealership and when I contacted them they replied that they weren't obligated to honour the previous deal. Consequently I took my business elsewhere and ordered some more OEM goodies online from another dealer (in MA) including the missing mounting bracket. Had a friend who has a building renovations company in MA receive the goods in his warehouse, where one of his logistics people unpacked and then repacked the goods, so my friend could being with on his next trip to China (he trips between USA-China 6-8 times per year). Long story short, that friggin mounting bracket wasn't in the package. Friend never saw any of the goods himself, though he checked with his logistics people who swore they un/repacked everything and nothing was misplaced. The dealer swore they sent it, so I ended up wearing that one. So I've had my Dragstar fitted with everything except those driving lamps. Fast forward to now, and I'm thinking of going with a set of LED lamps with a round clamp fitted to the indicator/turn signal bracket so I don't have to worry about trying to obtain that elusive driving lamp mounting bracket for a third time.
Since I'm looking for LED style lamps for the Dragstar I also want something inexpensive for the S10 as well. I've read lots of reviews on a range of websites including web bike world
http://www.webbikeworld.com/lights/ ;
http://www.clearwaterlights.com lamps,
http://www.bikevis.com,
http://www.optronicsinc.com available through Walmart

and many others.
For the Jetmax, I changed out the 35w halogen dual headlight bulbs and went with 25w HID lights although the packaging has 35w printed on the outside. They are a Chinese brand bought locally and work well, fairly bright. I also swapped out the small little T10 park light bulbs with a pair of T10 4w LED's which are bright, but not big enough to be seen with gusto from any kind of distance especially during the day. Since the scoot has a huge surface area, I'm thinking about either multiple LED's like bikevis or a LED light strip.
I'm looking at a few different options for all 3 bikes, and even though some of the vendors are having their products made in China (optronics being one), I can't seem to locate any on the ebay equivalent in China - taobao
http://www.taobao.com the majority of products are for cars and the like.
At the same time, I'm very interested in some LED strips, like what AUDI and BMW et al. are putting on their cars, these are a bright white when on, and figure something like this would help my bikes standout during daytime riding. Lots of choices in this area.
Likely will go with some PIAA which are being sold via a auto accessory company

using the B2C taobao
http://item.taobao.com/item.htm?id=9595187215 platform although these look like they are supplied as a car application.
I'd go with the Optronics lamps based on the price alone, somewhere in a vicinity of $25-30. Just have to get them into China unscathed.
Just my 0.10c
