I put those in my mazda3i when I had it. I was scared as fudge when they told me I had to bake the lights, but it aint that bad, you heat them, take them out, take them apart, put them on, put them back again and with a hairdryier, heat them together, let it dry for a minute and its back to normal. Had no problems with water or stuff getting in them. After I put them on I receieve a lot of compliment and thumbs up from passer bys...more than my wheels that cost me more lol. They look great during the day, at night they look good to but with the headlights/fog light, they dont stick out as much as in the day. Definately a good mod.
