Turn signal help
1980 corvette installing new wiring harness and cant figure out the turn signal lights. On the diagram it shows 3 lights in the front. You have a directional/park light with 3 wires, cornerning light with 2 wires (bigger bulb) and a marker light with 2 wires.
1.) The dual filament bulb should be clear or yellow? 2.) Does the dual filament bulb plug into the front of the car? Or the side light?3.) The marker lights on the front side are yellow and clear. Do they both turn signal or is one turn signal and the other marking light?Thanks in advance for the help

The dual filament amber lamp is for the park/turn lamps below the headlamps.
On the side the one with the amber lens is the side mark lamp; the one with the clear lens is the cornering lamp (cornering lamps turn on constantly as their respective turn lamp flashes). The cornering lamp should be physically larger and higher output as it is supposed to provided usable illumination to the side you are turning--cornering lamp units vary greatly in their ability to achieve that goal

Thank you for the information. I was thinking that but not 100%.

That marker lamp wiring is dual purpose. It will light up with the headlights but also flash with the signal. However, that wiring only works if the bulbs are filament bulbs. It won't work if you use LED's.
