Fog Lights?

Hey there, long time no post! Anyway, on to my real question. I've seen someone on here a while ago who had a 03-05ish Silverado (can't remember exact year, all I remember was it was either black or dark green) and they installed fog lights inside the grille, and I think it would look cool on my 1998, I was just wondering how complicated, pricey, and if it will even work with my truck. My trans cooler is (I think? The little radiator looking thing on the front of the radiator) in a not so good place, so I'm not sure if I could make them fit. If they would fit, what brands do you recommend, what sizes, halogens, no halogens, what should I do? I don't want to go too all out on it, I just don't want to get them and have them be POS's and break within a couple months. Thanks for your help! Let me know if I'm in the wrong place and I'll move it, thanks
