I need help with the overnight parking light's

[A horse with no name]

Hi, I have had no need to use them, but the overnight park lights did work in the past...When I now switch to turn on the overnight park lights, say the right side, all of the park lights, both front and rear go on. This happens when I switch to the right or to the left side. My brake, turn signals, including the four way flashers, work well... If anyone can help me out with this issue it would be most appreciated.

Thanks

We may be beating a dead horse here but, does the knob-switch pull out and then rotate too or does it only rotate L & R ?
And wasn't there an era when you lifted the turn signal lever up for right curb-side parking/overnight light, or pushed it down for left street-side parking/overnight light ?
I'll Gandalf-guess that it's a worn out or partially corroded or shorting relay or the switch in the circuit. Then again, my name's not Con-Edison, nor Einstein, nor Lucas:Prince of Darkness

No, it's done with the turn signal switch. This is provided while there's no key in the ignition. Just turn your signal switch and the light will turn off, there are two steps in the switch for each side.
