Yes headlights are the best mod in my opinion, the bike looks so much better with them. Since I live in Thailand, I bought them from Bangkok, here is the contact, they can speak english more or less, and I used line to contact them (app for smartphone):

I don't think there is a need for BK Moto to wait, as the lights are universal, installation was relatively easy, just wiring and electric was difficult. I just got a local mechanic to do it... But in terms of fixing it, the headlight enclosure had to be open, the reflector was taken out, and then the new lights just fit in place of the old fixtures... I do not think this set was designed for R3, but it fits perfectly. And the LED strips were easy to install yes. The lights are called "angel eyes" projector head light...
And here is the video of the exhaust sound, but it sounds much better in real life, in my opinion the microphone on whatever device used does not really capture it...

Also Devil is a french company, but they have a factory in Thailand now, so this model is made in thailand.
About mirrors yes I think red, but yesterday I find another thai store:
http://www.kdprojectracing.com/product/1245/mirror-aluminum-cnc-red
And they are selling pretty awesome looking alluminum mirrors for only 30$

it is 10 times cheaper than the original ones I posted. So I think I might go for those, with red accent, yes.
And also better clutch and break levers, and a rear fender eliminator.
Bu the way, ordered yesterday an LED tail light, which eliminates the need for rear turn signals all together, but also ordered 2 pairs of barracuda "Futura 2" turn signals.
