Mike,
You are referring to lights below the headlight, in the grill, and on the top of the fenders?
Any chance you could post a photo? People have been very creative in the location and the style of additional lights.
- In the grill were Chevrolet truck parking lamps.
- Below the headlights on GMC trucks (and 1954/55 Chevrolet trucks) were parking lamps.
- On the top of the fenders was a common location for after-market directional signals.
