I have a 1985 Spree. I recently got some LED lights for Christmas

For the headlight swap, I have some questions.
1. Is this even possible on an 85 Spree?
2. If so, is it easy (like, for instance, plug n play, or is wiring and electrical skills required)?
Thanks so much for help in advance!
If anyone wants pictures of the lights I got, please let me know.
