Yes, the noun 'jacket' is a common noun, a general word for any jacket of any kind.
It should be two words: life jacket. But it is probably better to hyphenate it as life-jacket. The two words are inseperable and make a concept different from what a jacket is--a life-jacket is not a kind of jacket. Semantically, they form a single word. Probably in due course it will be spelled as a single word, but in the meantime use the hyphen.
