I just ordered all of the parts to put OEM fogs in my 2019 Altima SR. There are a couple of Nissan OEM websites that you can order the parts, your going to need: a new steering column switch(the one that has fogs), foglights, bezels and screws/washers.
It really depends on what you are after, you can go the OEM route or you can go over to Ebay and purchase an aftermarket kit that will have everything you need. The only issue with Ebay is that your going to have an aftermarket switch to turn them on or your going to need to splice into the wiring harness.
As for the headlights I have found a couple of used and new sets on Ebay but its going to cost you some money to go this route, if you are looking to go the cheaper route you can always upgrade both your low and high beam to a high quality LED bulb.
