But did the indicator light go off?
Haynes manual describes this procedure on page 12-6, section 10.
There is an adjusting screw located on the connecting link that screws onto the adjusting rod.
It is located just behind where the microswitch is located when the lights are up.
When properly adjusted the flat end of the connecting link will touch the buttons on the microswitches and turn off the indicator light.
It is possible that the switches are worn enough so that you have adjusted the linkage too far and it is past the fulcrum that will allow it to be shut.
Try backing off the adjustment until the lights go down on their own again.
If the indicator light stays on at this point, you could replace the switches, you could tape the buttons closed so the light goes off or you could unplug them.
