See my profile, I do not know your rig well.
The 1st place I would go at this point would be the actual "BRAKE SWITCH".
I'm sure a CJ switch is different than yours, however function should be the same.
My 1977 CJ 5s is located near the top of the Brake Pedal, and is a push button switch (pushed in is off).
My 1946 Willys is a fluid operated pressure switch located on the Master Cylinder (on Willys, under floor pan).
In either case, They are a OFF-ON switch with 2 wires....... Basically1--12 Volt wire, with a Switch in it.
On mine, with your situation, I would unplug the wires off of the switchthen run a "Jumper" between the 2 wires. This would, "Act as a switch" and my lights would come on.
Thus either confirming or denying that the Actual Switch is not working.....Or whether to continue searching for another cause.
Even new stuff could be bad or incorrectly installed, or movement not enough to activate it.
The Actual switch can be tested with the wires disconnected, and a Voltmeter set to OHMs, to run a Continuity Test thru it....while on/ off the Pedal with your foot.
If you have antilocks, maybe there is a pressure switch on it somewhere.
A manual would really assist you, in finding and testing!
Good Luck, I hope its simple, like the wires have come off of the switch!
Reply back with your findings, or if I need to explain more.
Love, Turddog
