Just picked up my 05 Roadster Limited yesterday and see some fogging in the driver's side light. Just on the high-beam side, though. Canadian car I bought in Toronto, so I've got the daytime running lights. Anyhow, having the daytime lights didn't seem to help this Roadster. Dunno if the problem is bad enough to warrant a replacement. Not sure if this is a weather thing, or was exacerbated by how the dealer washed the car just before I took it out in yesterday's amazingly cold weather. That wind could cut you to the bone. God, bring on April already. Seems to be better today.
