Signal has 3 wires exiting out the back of it. FITS THE FOLLOWING BIKE APPLICATIONS. OEM CROSS REFERENCE PART NUMBER(S) Manufacturer Part Number: 8501A.
The lights were very nice, however I was unable to use the lights on my motorcycle. They did not come with the mounting hardware and were 3 wire lights and my turn signals are 2 wire. Just verify the fit before you buy.
