Bulbs in clear taillights question...

I've ordered the clear taillights for a 92 civic si hatchback (not euro) and I just need to know how many clear bulbs (they have red lights in them) I need. Is it 2, or 4? Are the red lights that go on when you turn the headlamps on the same lights that go on when you press the brake? or are they two diferent ones? Heres a pic of the bulbs.

more than likely youll need 4 bulbs.......prolly 1157,those are dual filament which are dim when the headlights come on then when you press the brake they get brighter.......you will also need 2 1156(single filament)bulbs for your turn signals and 2 more 1156 bulbs for your reverse......at least thats how my 4th gen accord is, if im not mistaken your tails have 4 pieces,if they do then thats what youll need:sun:
