I would replace the headlight switch as Ford has had their share of these problems.
The parking lights are turned on when the headlights are on and you pull out on the light switch. The parking lights cannot be turned on by themselves.
If you turn up your interior dashboard light settings, then the radio display will be brighter too. The radio dims to the setting for the dashboard when the lights are turned on.
The middle two lights should be on when you turn on the headlights.
Break lights come on when you step on the break, they do not come on when the head lights are turned on.
Because you have to eat french fries with ketchup!
the dash and radio lights are supposed to dim when the headlights come on. Make sure you have the brightness of the dash lights turned up as much as possible.
Perhaps you turned on the interior lights when you were adjusting the headlights?
It may be wired wrong.
Brake lights should NOT be effected by the headlights. Brake light function is completely independent of the headlights. Assuming you are not refering to the tail lights, or marker lights, which are supposed to come when the head lights are turned on. Not having brake lights when the head lights are on is a big safety problem and should be corrected.
First thing you want to check is the dimmer switch to see if it is turned all the way down.
is there anyone who knows the answer?
Short to ground in the circuit or a faulty chassis node.
The dash lights and the tail lights are on the same fuse. In all probability, you have a short circuit in the tail light wiring.
It is important to know what is going on inside of a vehicle. The headlights dim when a stereo is turned on or turned up because power is being drawn away from the lights to the stereo.
hi i think that is your oil level
sounds like a bad light switch.
It's a relay. Which one it depends... I would start from testing headlights relay.
Rotate the headlight switch knob left or right with headlights turned on.
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
They are either the wrong bulbs or one of the filaments is burned out. The bulbs should have two filaments. One is illuminated when the lights are on. The other is brighter when the brakes are used.
i found it to be the tail light harnesses go bad . a common problem with them because the bulb sockets short out.
The parking lights may stay on because the headlights have not been turned off completely. If the car is parked, the key is out of the ignition, and the headlights are turned all the way off, the issue is in your electrical system. It will need to be taken to a mechanic to be tracked down and repaired.
I have a 2006 Pacifica. If yours is equipped with fog lights, grab the end of the left light control tree, and pull firmly. Then, have the parking lights or headlights turned on. You can't have just the fog lights on.
Check the bulbs - they are double filamented larger for tailights and smaller for stop/turn Check the fuse for parking/tail and dash lights
