VERY Small
If small and BRIGHT is what you're after, these are the answer. Bought front (2 wire) and rear (3 wire). Super bright! had an issue with 1 of the rears, wired as turn and brake (wouldn't come on very bright in brake mode), cross checked by swapping sides, all good with other light, getting a replacement. But, these are very nice.

Bright light in a small package
This is a great product and exactly what I needed. I installed as turn signals on a chopper. The light is very bright / visible, but in a small package that you barely notice on the bike. I also purchased this accessory (Kuryakyn 2568 Motorcycle Lighting Accessory) because the hole I was putting the light into was larger than the light stem.

Amazing
It is an amazing thing, it shines perfectly and very sharply, it is very beautiful and very small.It is very high quality and enriches the motorcycle. Probably all of my future motorcycles will just put this on

Only 1 signal
Did not read close enough to realize you are buying 1 signal! It's nice they offer that should you need to replace it at that price point but seriously? Who buys 1 turn signal??

OPEN PACKAGE, ITEMS MISSING
Bought two of these, one package was opened prior to receipt, the nut for securing the light is missing, as well as the crimps, heat-shrink and instructions. $70 is a lot to pay for a used item that's missing parts.

Super bright and small
These are excellent and expensive but you pay for what you get. Very well made and they are super bright / super small. I don't think it can get any better than this.
