The period lights for the '67 Overlander are the oval "non-bullseye" units. The cat's eye marker lights I linked are the closest to OEM I could find on a marker light, but I'm not sure how they attach to the skin. Right now, I'm just getting the lights working for the tow. Even so, I figure that if I buy good running lights now I can just use them after the trailer has all new copper wiring throughout. I really like the LED for visibility, low draw and low maintenance. I just don't want to get too funkadelic in terms of appearance... although I have to say some of the lights are kind of interesting like
this or
this. I may order one of the catseye lamps to see how it looks. I'll post my results... or the lack thereof.
