Helping my buddy fix his New Holland TC33D tractor because the headlights just went dark. He knows nothing about it, but I’m guessing it’s a blown fuse, but since I’ll be digging around in there anyway, I figured we might as well swap the old bulbs for some LEDs.
Has anyone done this swap on a TC33D? I’m looking for recommendations on a specific brand or model number that’ll actually fit, and the best spot to grab them.

Also, if there's a common reason these lights cut out besides the fuse, let me know.
I’m starting with the fuse box, but any tips on the LED upgrade would be appreciated.
 
Absolutely, blown fuses are a classic issue. I’d definitely check the circuit before swapping in LEDs, but those LED replacements usually brighten up the night. Just make sure to choose ones that fit your existing sockets, and you’ll be all set
 
Fuses are definitely the first thing to check.
LEDs are awesome, but don’t forget to verify the polarity and pick ones that fit the TC33D housing.
A quick clean of the harness can often prevent flickering down the line too.
 
I’ve swapped out LEDs before, just ensure they fit the stock clips and keep an eye on the polarity.
Also, check for any loose ground wires; that can be a sneaky culprit for lights going out, aside from a blown fuse.
