Please 1999 jeep grand Cherokee why does your right brake light turn off when headlights are on?
This will happen if the ground terminal for the brakelight bulb is connected to the power side by accident. If you have a 3 wire socket or light assembly with GROUND, TAIL, and BRAKE wires two of them are wired incorrectly. When the headlights are off the brake light is finding ground thru the filaments of the headlights. Since the headlights have much heavier filaments, they provide a good ground for weaker brake light. When power is on the headlights the brake light will have power on both sides, so no current flows and it goes out.

How do you turn off headlights in a 1998 Oldsmobile silhouette when it is running?
You can only turn off the headlights by applying the emergency brake. When the emergency brake is on, the headlights will not light. Otherwise the best of my expererience is that they are on all the time. If you have remote start, put the emergency brake on before you leave the vehicle and when you remote start it, the headlights will not be on, but the driving lights (if switch is on) will be on as well as the parking lights.
