Thanks a lot for the reply. I think that if both the owner's manual and Sylvania say H16 then that's what I'll go with. The last time I bought a pair of low beams via Amazon, it said they would fit. But they did NOT fit. You're right about the Philips link. But what's even weirder is that I checked each set the search produced, and found that the size varies based on which particular grade of bulbs one chooses (HUH?!?). One even says that it replaces H7, H8/H16, H11, 9006, 9145, and PS24W. Some of them appear to attach at the rear, and some at the side -- so I know some of them can't be correct. Well, I'll buy a pair of H16s and just keep my fingers crossed. Thanks again for replying!

This is Alla Lighting’s page specific to a 2013 Subaru Legacy, and it says all these fog lights will fit correctly(!). You can tell that the ones for $29.99 appear to attach in a very different way than the ones for $79.99: https://allalighting.com/pages/bulb-finder-shop-by-vehicle-led-light-bulb-car-truck I asked them which ones are the correct ones and they said H16 was the right size, but also said that the H11 and H16 sizes are interchangeable. Another time they said that “Per your vehicles owner manual, H11 bulb size will fit fog light housing.” When I try Amazon and do a search for “2013 Subaru Legacy fog lights”, I get results that are also in sizes HB3, H7, H11 and 9005! Amazon says all of these fit in the fog light sockets. And if Alla says one of their light sets will definitely work on my Legacy, Amazon will say the exact same pair will NOT fit! At this point I’m about to pull my hair out… All I want to know is the correct size so I know what to buy. Can someone PLEASE tell me?? Thanks!
