These are honestly beautiful, if you’re willing to work with them and properly do it then the ending will be worth it. Seal the crap outta them. Do NOT let any hole be uncovered. Only thing I didn’t seal was the back vent. These are obviously mass produced so there’s gonna be errors, seems like it’s probably machine made. Anyway, seems like there’s a glob of glue on all of them, had 3 replaced and the glue drop was on the center in all of them, you can actually see it kinda in the promotional pictures, anyway, I sealed them, coated them in Meguiar's headlight coating spray, to protect from turning yellow. I bought a pair of LEDs which is a must!!!! Im using “FireHawk 2022 New H7 LED Bulbs” from Amazon in these and they work great and are bright!!!! Now onto the moisture, mine fogged up a couple of times in the beginning however it’s been through HEAVY thunderstorms and it seems to have not gotten a single drop of water inside or mist “knock on wood with me” they stopped misting up after the first week of having the silicone on. And gotta say I’m extremely happy with my purchase. Just hope that they never go bad. Had these for I think a month now.— 06/12/32: UPDATE ON THE “ FireHawk 2022 New H7 LED Bulbs” they gave out this month, the oEdRo headlight housing assembly is still working perfectly. Still very satisfied with my purchase.
