I had it on my Ducati Scrambler (tucked) before I sold the bike, so i figured i would get one for the my Thruxton R as well since i liked it on that bike.
I got the regular version (plate sticking out). My order came with the LED lighting premounted backwards on the plate and the wiring too was backwards (left signal was turning on right LED instead). It was an easy fix to say the least (NRC Customer Support are very quick in answering your questions\concerns). Mounting was easy (although it was a tight fit). Build quality is good, it almost looks like they 3D print the LED outer shell, therefor it'll have a rough finish (once installed you won't be able to tell).
LEDs are bright and i too asked my girlfriend to drive behind me to verify if she an see the turn signals and brake lights. She says she could, so i was happy.
**Just be prepared to clean the rear cowl\seat more often (even with the regular plate location version)
If you plan on keeping the front signals Halogen, then you have three options
1) Install and leave the flash bike settings to "Type 1". You will get "hyper flash" but your emergency lights will work and at a normal rate
2) Set the bike flash rate to "Type 3". The flash rate will be normal with the NRC rear and halogen fronts, HOWEVER, when you put on the emergency lights, it'll short out causing the turn signals not to function at all until you turn the bike off and back on again. (type 2 and 4 will just short everything out)
3) Install, add two resistors (one for each rear turn signal) and leave the flash bike setting to "Type 1". Emergency and Signal rate will be normal
*4) Change your front turn signal to LED (either Bulb wise or entire housing) and play with the flash rate "Type 2 thru 4" settings to get the proper flash rate.
