Marker lights flashing

I just purchased my dream car, 70 convertible, and I have a problem? with the lights. Are the rear marker lights supposed to flash with the turn signals? I have never seen the rears flash on a car but theres always the first time. Thanks.

Yes. Both front and rear marker lights flash with the turn signals in 1970.

Thanks!

Is that 1970 only. Reason I asked is because I downloaded a diagram for a 69 and it shouldn’t flash the marker lamps.

The side markers do not flash with the turn signals on a 69.

70,71,and 72 have side markers that flash with the turn signals, 69 and 73 do not.

OK, thanks everyone.
