No parking lights and front side marker lights

I finally broke down and bought one of these a few years back. It's like an old 12 v test light on steroids. Once you get the hang of it, you can check power, ground, continuity etc in seconds.

I would start where the forward light harness attaches to the firewall and find out if you've got power there? If no power at the firewall going forward, I would look at the turn signal switch. Mopar engineers liked to run important circuits through switches and guages for some reason??? Bad turn signal switches and connections have caused me to pull out more than one handfull of hair over the years.
