I have to purchase a new pair of fog lights/ DLRs for my 2LT/RS because I noticed condensation was getting in after I modified them to insert LED halos. When I go to purchase them online from gmpartshouse I am given the option to purchase the foglight lamp housing which are about $80 or the DLR lamp housing which is about $70. What is the difference between these two housings and which one would I need to purchase for a 2LT/ RS. Ive gone through a few threads about the DLRs vs Foglights but they have only confused me even more!!
