the oem fog light comes with a 7440 harness with 7440 bulb which is a single filament. thus, it has the always on look.

you can modify a 7443 harness with 7443 bulb to fit inside of the oem fog light. the 7443 bulb has dual filament that has the low/high intensity for parking/brake features. i'm personally using a wal-mart or sylvania brand of bulb that cost me around $2.

hope that cleared things up for you.
