Just to reiterate:
Yes, the corner lights on an 93+ MX6 are completely clear. The only thing that has color is the bulb itself. it is Amber in color. If you look at the corner light from the outside, it will look amber. However, that is only the color of the bulb reflecting on the inside of the light.
On a side note- There is a company now that makes these bulbs that are completely clear. They have a chrome coating on them but if you look at them, they look CLEAR. But, once they are turned on, they flash AMBER. This will look excellent in our cars by leaving the corner light completely CLEAR during the day and only flashing ABLER when turned on.
