Even though it took us 3 try's with miss marked packaging JP Cycles went out of their way to help me get the correct part for my bike. Thank you Don I appreciate your follow through.


Good thing i just checked this part number and the previous review. i must also have the incorrect unit and will need to return.


Had to return because my it was the wrong part. This part number is for the Dual Intensity Brake Light, not the Flashing, Knight Rider" style which is described. First time I have ever had to return to J&P in the 3 + years I have been shopping from them. Return process was simple and painless. Currently waiting for the correct part to be shipped to me.
