Many compound adjectives have the main stress on the final element. Examples are
light green long-haired user-friendly
However, as you might expect, there are exceptions to this. Adjectives ending in <-proof> have the main stress on the initial element. Here are some examples:
fireproof ˈfaɪəpruːf
foolproof ˈfuːlpruːf
soundproof ˈsaʊndpruːf
waterproof ˈwɔːtəpruːf
