Lighting issue

Hello everyone, I have a 1985 atc110 the im restoring. My dad bought it for me and my brothers when we were kids. It’s been sitting in the garage since 2008. Put gas in it the other day and it fired right up. Awsome news. The head light and tail light are not light up. I changed the bulbs and still nothing. I could really use some help on this issue. Any suggestions? Thank you
