This is the way we put "custom" turnsignals on the rear of Pams S40. These are off the front of a Triumph SpeedMaster. We really like them as they sit closer to the fender and they are made of metal. We used the factory harness all the way to the bulb and rerouted the wires under the fender and then up thru the same hole the tail light goes thru. They are a bit larget so more vis too. We put small reflectors where the stalks of the factory lights went to dress the holes. Pam likes the look. Makes plenty of room for the saddle bags too..





 

Very clean.  I like the reflector idea to cover the old holes.
