Do the back lights do the same? Check all you bulbs for a filiment that broke and is crossing over to the running light side. Check your grounds.

You don't have a problem. What you describe above is proper operation. The lighting assemblies behind the grill are combination parking/directional lamps and have a dual filament bulb.

The parking light filaments are connected to the brown wires and only come on when the main headlight switch is pulled out (either halfway or all the way).

The directional filaments are connected to the light blue (LH side) and dark blue (RH side) leads. These leads are powered through the flasher and the directional switch in the steering column. They are independent of the headlight/parking light circuits.


See if this makes sense:

In the daytime (headlight switch pushed all the way in) the parking light filament is dead. The directional filament is also dead - except when the directional switch is moved up or down. Then, when the switch is moved, the filament on whichever side selected receives a pulsed signal from the flasher.

In the night time, when the headlight switch is pulled out (to either the parking or headlight position) the parking light filament is energized. It lights up and stays that way - until you push the headlight switch all the way back in. The directional filament operates just as it did in the daytime - only lighting up when the directional switch is moved to the up or down position. The headlight switch has no effect on the directional filament.
