I installed SOS Priority Plus and Lites for my MP3 500 for more safer appeal on the road. The SOS Priority Lites make the two front turn signal lights to be turn signal with running lights future. The SOS Priority Plus make the two rear turn signal lights to be turn signals with running lights future also to be an extra stop lights with pulse future.
I also upgraded LED light bulbs for two sets of stop and tail lights. This up grades make MP3 much more recognizable while driving on the road and especially when you are stopping.
For using LED lights bulbs: I contacted SOS priority and spoke with "Doug" since there was small concern about LED bulbs. Doug was very kind and detail, he explained me that there will be 50/50 chance with combination using LED because LED are not DOT rated and there are always an electric currency there even lights is not on. I purchased high quality LED 1156 bulbs and tail bulbs and I set all up with the original bulbs and make sure everything works and then swapped with LED's to assure all circuits works.
Now running with all four turn signals as running lights and two rear lights are function as tail and stop lights with pulse. Addition to much brighter tail and stop light. It works so well. (note: Rear turn signal bulb's color has to be red color not yellow or amber when function as stop lights. Please check you local state for the law and regulations)
