Slick 60's

Looks like a deer whistle.

I think it's from the James Bond era. Mounts under the rear licence plate.

Sprays oil on the road when the Evil Blofeld gets too close.

Those little things were mounted on the outer ends of the header panel and a 4" turn signal screwed into the end. I know they were used on the 64's and some of the heavier slicks. They were required in some states ie: Pa at least. The grill lights then used 1 wire and were for parking only.

I have a set on my 66 Wrecker

That's the first time I've seen anything like that. Anybody have a pic of one in action?
