Tinting works - there are lots of examples on this site of what you could do. Some people put red film over the turn signals and others use niight shades (I think) to tint them like windows. But because you have a yellow car IMO, I wouldn't tint the taillights though because they will really stand out. As for replacing them I would stay away from the Ebay 'Carbon Fibre' 'Altezza' taillights - to me none of them look good. The only other option are the JDM taillights which look very similar to the Protege sedan taillights but are a different shape. I personally like these best and is what I have on my car right now. Unfortunately these are the most expensive and you can get them from places like
www.corksport.com or occasionally they pop up in the for sale section. I have a pic of them on my car somewhere...
