Brake Lights don't work(???)

[Jerry Hotdog]

I have a 2005 Mahindra 2535.

My brake lights stopped working intermittently a few weeks ago.
I attempted to follow the wiring as best as I could without dismantling the tractor. I did not see any cracks or grounding issues.
I checked the bulbs, even though they do come one when I turn on the head lights. All bulbs are good and work. I check the fuse, it is not blown and tester indicate no disconnect. As best as I could see, the wiring to the back of the fuse box appears to be connected.
I then replaced the spring loaded brake switch Absolutely no affect. Now the brake lights don稚 come on at all.

Where to now? Due to the intermittent activity at first, I figure it is likely a short or ground issue (maybe?) but have not been able to locate. I turned on my hazard/flashers last night and only one side will flash. They both flashed a few days ago. What痴 going on with the electrical system on this tractor?

Any suggestion would be greatly appreciated.

Check the actuator on the brake pedal itself.

Pardon my ignorance, but what is the "actuator" and where is it?

I replaced the Brake light switch. I attempted to attach a picture of it.

I notice that when the brake bar is locked the brake lights don't stay on, which I assume is the way it is supposed to be. But, even when I pull the brake switch sping all the way down they still don't work. The small thin spring comes out of the switch and hooks to a small hole on the brake peddle. When the peddle is pressed all the way down it pulls on the spring.
However, pressing the peddle or pulling manually still doesn't work for some reason.
Is the welded piece on the brake peddle the actuator?
Thank you friend

I would be checking all of the ground points.

I was afraid someone was going to say that Well, I have my work cut out for me. I知 glad I have next week off work.
I will report back should I find a resolution to this irritating problem, and thank you all for your input.
Please have a Merry Christmas and safe travels to those who will be doing so.
