amber corner lights

i just recently bought a 92 eg hatch and was thinking about adding 2 amber lights on both corner. there are quite a few of them and wasn't sure which one to choose from. do they all work the same way or different? are amber lights necessary for JDM hatch? i heard pple talk about JDM style for civic hatch all the time but i have no clue what they mean. any recommendations would be helpful thanks.
