Can I replace my headlight assembly myself?

Hey there! I'm wondering if I can replace my headlight assembly myself instead of taking it to a mechanic. My headlight is cracked and needs to be replaced, but I'm not sure if this is something I should attempt on my own. I'm pretty handy with basic tools and have done some minor car maintenance before, but I've never worked on headlights specifically. What do you think - is this a DIY-friendly job, or should I leave it to the professionals?
