I used to be fair weather / daylight only cyclist but have now started going out in the evenings / dark and intend to do so throughout the winter but probably not if it's chucking it down with rain.

I was having a look at jackets as I probably need more visibility as much as anything and had a few queries, the lightweight ones appeal as my thinking was ... if it's windproof I can just put more layers on underneath when it's cold and yet still use without so many layers when it's not so cold.

Will that be warm enough in the winter when peddling reasonably hard or will I really need to go for something that's more specific to winter usage???

Also I see quite a few of them now are blue, do they show up as much / are they "fluorescent" like the more traditional yellow / orange high vis jackets????

If anyone has any recommendations it'd be appreciated as well, I don't want to spend a huge sum of money at the moment as I may get half way into the winter and decide it's not for me after all so more looking at the Seat rather than Rolls Royce end of the range for now.
