I have a 2016 Can Am Outlander L 570 DPS and like others, was confused on what type of bulb to use. If you have a Can Am, they use different type bulbs in different models. So if you have a 2016 Can Am like mine, it's an H4 bulb.These bulbs are easy to install and look great. Literally plug and play. I have a picture of the new Nilight bulb on the left with a stock bulb on the right. They are bright and for the cost, it's definitely worth it.
