I believe no JDM Prelude's had the rear reflectors in the rear bumper. Well I havnt seen any and all we have are JDM Prelude's.
The outer lenses on the front bumper (beside the indicator) either have a light or not. They are optional. Mine have a bulb but arnt hooked up atm.
Pic of mine with fender "Indicator" lights. Look just infront of the door and behind the wheel. it's that clear long thing..
They come on with the indicators because then whoever is beside you (bike, car etc) and they cant see your front or rear know if your indicating their way. That's all they are for.
