I have a 2013 Skoda Spaceback and I have noticed what looks to be like frosting on the inside of the front headlights, If you look close enough it seems to be many tiny fractures across the whole lens. This is also effecting visibility in my opinion as when the lights are on they are more evident. now I have come across lens replacements on Amazon which seem like a good option to go for instead of changing the whole unit. https://amzn.eu/d/gVfx6t0 My question is this, would such replacement be possible? As I have no idea how the original units are sealed ; as the lenses looks like they have tabs which lock in place maybe around a weather strip to keep moisture out or if the units are indeed sealed with a sealant and you would have to bake the units to loosen the adhesive. any information would be appreciated
