Those look like the same type you can buy from Tractor Supply from China. They are sealed so you can't replace the bulb in the future. Originals updated to 12 volt is the best long term option in my opinion. But it's your tractor so it's up to you. I would keep the originals for the next guy if you decide to sell it in the future.

What I mean by "sealed" is, the plastic light housing is hard molded plastic with the bulb inside the plastic. There is no rubber seal that I could see. I purchased two of these lights at Tractor Supply for my MF 65 and took them back. One did not work out of the box. When I found the bulbs were not replaceable that was enough reason for me to return them. Just what I found. To each his own.

"They are sealed so you can't replace the bulb in the future." That "rubber" housing probably has enough elasticity to permit changing the lamp.

I would have refurbished lights if I had them, but you can't get junk lights for what I spent on these. The ones I bought do have replaceable bulbs. I cut the bulb number off the box and hung it on my pegboard, but haven't had to replace one yet. I have no idea how much the bulbs cost or how much trouble they are to change. For me, I need my cub to do work and I needed lights, these lights took care of that need, which made me happy. Like John said , if I wanted a tractor for show, I wouldn't be knocking my muffler and headlights around with tree limbs.

Harbor freight, same light 7.99...

The topic is 12 Volt head lights-- to be sure.
As far as I know the Harbor Freight lights are available 12 volts only. Those seeking 6 volt should shop elsewhere. For those who may have a burn-out of a 12 volt unit, the HF unit may possibly have the equivalent lamp of yours. The $7.99 might be lower price than just the lamp alone from some other sources. So the HF unit might be a donor for the lamp for your different housing. Perhaps it is worth investigating.
