I'd be careful about 55w HID, they really have only minor brightness increases over 35w at a much higher temp and likely would overwhelm the housings designed for 35w... But yeah, I heartily recommend the Morimoto 2stroke 2.0 as being the brightest our factory halogen reflector housing can handle and I can see myself not bothering with the TYC Euro's and start saving for a turbo upgrade
Another housing option is Hella, if you are interested in brand-name aftermarket, they have
units at $300 each side, so about the same price as the Ford Euro OEM but look even higher quality
Now, if you are really going to go with the OEM housings then I'd recommend even the TechMax as a temporary solution for $35, they are 90%+ as good as the Morimoto while also being simpler with no external driver module and extra adapter pigtail to tuck away like on the Morimoto, or maybe even the Nineo at $50, it just depends on how much you want to spend now and then spend again on H7 bulbs for the new housings later... I originally started this thread as I was tired of all the crappy, glaring sets that people rate 5 stars on Amazon so I was happy to find a real review site, and now we have proof pics to share with each other instead of no-photo 5 star reviews on Amazon to go along with real testing!
