Outdoor lights not working -- switch or lamp? Also, other light-switch issues..

I've got two outdoor lights/lamps in the front of my house. They work off of the same switch. One stopped working at one point, and then the other stopped working about 6 months later. If both had stopped working at the same time, I would have thought that it's the switch. Since one stopped working and then the other 6 months later (and like I said, they work off of the same switch), I'm unsure if the issue would be the switch or the lights/lamps. I'm not a handy guy and by no means an electrician, but I'll try to do work like this by myself to save money. These projects normally take me a while because I'm hesitant due to my inexperience. Does this sound like a switch, light/lamp or even an electrical wire issue to anyone here with experience/professionals? Any help would be appreciated. Best regards,
