If you have an open station and no radio, the type of LED lights don't matter much. But if you DO have a Radio, the LED bulb type matter significantly.
I purchased an NILIGHT LED bar and a couple smaller lights. I put the smaller lights on the back, replacing the factory halogens. I immediately lost all signal to my radio. The LEDs were 'generic' and created interference. I was unable to fix it with any sort of addition, so I ended up removing them completely. After more research, I purchased another set of LEDs with CREE LEDs. I put them on and have had no issues with radio interference. So, my recommendation would be to do some research if you have a radio on your tractor, and save yourself a lot of hassle. I won't purchase anything without CREE bulbs, just because of that reason. It isn't worth saving the few dollars, to spend a few hours putting them on then taking them off.
