When I say "tail light", I mean the light in the housing that is on when your headlights are on. When I say "brake light" or "signal light", I mean the higher intensity light in the housing that is on when you hit the brakes or when you signal.
It looks like your light housings are dual function. You will need to determine which wire on the housing is "tail" and which is "brake".
In most cases the brown will be the tail light, and the red will be the brake light.
Before you start,do your brake lights and tail lights function correctly the way you have them now?
The tear drops will work as front signal lights. Just make sure the light is bright enough.
