Marker light signals with headlights on?

Anyone know how to get your side marker/parking lights to act as signal WITH HEADLIGHTS ON? I can get them with dtrl mod and marker flash mod but nothing if i turn on headlights and that just wont work at night.

 

The only way this can be done unless the coffee has not kicked in.

Is to go to a dual filament bulb or install a second bulb one for marker lights and one for turn signal .

where you are do you need the marker light ?

using a trailer converter might be possible using those bulbs the same as trailer lights just thinking out loud

 

Might be possible to get dually leds....pretty sure they exist just not about tacos. Not sure if they are mandatory and the gov't speak is a bit confusing on that point.

 

These lights on my bumper are both marker and turn signal
