Anyone know what kind of turn signals these are?

I stumbled across this bike somewhere on the interwebs. I really like the turn signals on it. Does anyone recognize the brand? or know of anything that looks close? I want to get some smaller turn signals, but the new ones all look like bug antennae.

Looked here? www.kandstech.com/

Seems that those are the large DOT approved turn signals. The ones in the photo appear to be pretty small, so I'm willing to bet they are not DOT approved. I did track down where the bike came from, its a custom shop in Japan called Bulldock. I emailed them asking what kind of turn signals they use. maybe Ill get a response. Check out their website, there are some sweet Kaws on there, and some fancy Z1 rear sets. www.bulldock.jp
