1998 Dodge Dakota lights

Welcome to the forum, does the high mount brake lite work? the lower brake lites and turn use the same bulb filament, just not at the same time. Check voltage circuits at the rear, dark green wire with brown tracer is voltage circuit for brake and turn. Black wire with yellow tracer is voltage circuit for tail lites. Solid black wire is ground. Any fuse that applies, you need to use testlite, see if fuse circuit is hot when it should be. Some circuits are hot all the time, some go hot when you turn on the key.
