I bought the blu halogen bulbs for my 08 sportsman 400HO from a dealer. the right cat. # (checked twice by me and multiple salesmen) and they are 2-prong. My 2008 is a 3-prong! what am i missing. It's also listed as correcxt on polaris' website. are there 2-3 prong adapters?

 

Is your headlight a hi/low beam, or do you have a hi beam central, and low beam on the outer lights? A 3 prong would be for a hi/low light, 2 different elements, while a 2 prong is either hi or low beam, depending on how the element is set up. Not being a Polaris owner, I cant tell you if the dealer looked up the wrong part, or Polaris maybe didnt update the parts manual for your model?
