I would just be weary of the size of them. The FX-R's are honestly the best bet for these because they fit in the low beam area of the P5 lights perfectly, and are better than the TSX's for the money. Plus with the shroud it was a VERY tight fit but it works perfectly.
Also, if you email Retrofit Source and tell them Matt with the Protege5 sent you, they will add a 5% discount code that you can use upon checkout.
And BTW, the more you buy the more you save, ask them about combo deals and tell them you're on HID Planet for an even bigger discount. If you want to know more info Dub you can chat with me on AIM if you want.
