Hello everyone just picked up a 2018 500s and i love it so far!  Last machine was an arctic cat 300 4x4. 

Out of curiousity since i have not seen it anywhere can the 500ho headlights go on the 500s?

Welcome. I'm not sure but I suspect they will if the plastics are the same...also where there is a will...there is always a way..

Welcome to the forum and congrats on the new ride!

From the front view, the HO and S look like their plastics are slightly different.  Also, the HO has more lights than the S, so you would probably have to also replace the light controls on the handlebars. 

Thank you for the welcome and response.
