tail light bulbs in 1950 F1

[oneoldtruckguy]

Got the wiring pretty much done thanks to You Guys. Turn signals all working good. had to ground the tail lights to the frame good. My question is that the tail lights still seem very dim. My brake and turn signals are hooked up to the larger filament. tail lights hooked to the small one. Is that the right way to hook up?? Thanks Again Fordbarners!
