RESISTOR

If your indicator light flashes too quickly, or if other cockpit warning lights are incorrectly activated, after converting your turn signals, the solution to this problem is provided by the i.BOS systems (intelligent boxing operation system).

i.BOS - EL1 prevents incorrect activation of warning lights when DF combinations are used with original LED tail lights, e.g. BMW R nineT

You will need 1 set for 2 turn signals /2 DF turn signals (turn signal, tail light, brake light)
