I had an Exciter back in the day and it’s headlight was mounted on the bars. I hated it. If your carving left, you have to turn right to initiate the turn and your headlight is pointing the wrong way. It was always pointing the opposite way that I was trying to go. Probably better to go with a helmet light.
I’ve got the BRP Aux light as well as a custom bar mounted led from WPM. Makes it seem like daytime in front of the sled. Sled cane with them but I would invest in a helmet light over these any day. It’s more important to see where your going vs the direction the front of your sled is pointing.
