trav_19 - being my car is a cobra I don't have the 3rd light in the trunk lid, they came on the wing. If I had a GT and was gonna do that mod, I would put it on the outside, seems alittle cheesy to me, rather, I would take off the lens and put it on the inside so when the light came on I would show through in the SVT letters. Just my idea, but not the only way to do it. That being said, you wouldn't get any show points probably but it would look good on the street.
