I replaced the main tail light with the led from KTM Twins, didn't know there were 2 small bulbs hiding in there. Has anyone replaced the small bulbs? Googling around was pointing me to Phillips 5W5 units, but those seem to be more for interior lights, not sure if they would be happy in the tail. It looked like most of the threads here are for the main headlight and/or tail tidy kits. I'm really liking the look of the stock taillight with the duckbill and Rizoma plate holder so far, almost done with my build!

These are working great so far:
