they are located on top of the headlights, i looked for over 6 months for some originals without any luck. I accidently dropped one of the originals, needless to say the 84 yr old glass shattered into a fine powder . These are 3d replicas printed in translucent amber. I worked out a relay blinker circuit to make the marker lights work as blinkers too. If anyone one would like a wiring diagram to make the marker lights work as blinkers i would be happy to share the diagram .
