You only need this part if you want to keep your Original Triumph Indicators along with the Motone rear harness 

Sold as a pair - these adapters allow you to plug your Original Equipment (OE) TRIUMPH branded indicators into either an aftermarket loom (like we make at Motone for our tail tidies) - OR they also allow you to fit OE Triumph Indicators to non Triumph vehicles 

We specifically made these to help when you wish to fit one of our Motone tail tidies but you are either not quite ready yet to upgrade the turn signals, or naming no names (ALBERTO GARCIA) your girlfriend bought you a new set of Triumph indicators so you couldnt fit Motone Indicators but you also didnt want to splice the Triumph wires (so you can later resell them on ebay without damage when shes forgotten what they look like) and then come back and plug and play some Motone ones (We recommend the PICO for low profile of the ICON for more classical styling)
