foglights

[_VVTi_]

hi, i'm planning to buy a set of foglights for my 94 camry, but i have a few questions...
is there a type of foglights i should be looking into? projector style or just "lamp" style?
like a certain specification?
color output?
and most important...
then lower bumper doesnt' seem to offer me lots of space to put a pair of headlights, so wut size should i be looking into?

i could just go pick up a set of foglights at walmart for like $50 CDN...
