Near Intersection of I-35 & I-90 Southern Mn. | I got a set of our older 8310 and another set for our somewhat newer 8120. I believe they were from Tiger Lights. The LED style is the way to go. We were able to remove our originals without stripping the heads although a few were quite tough. Personally I wouldn't be too concerned about breaking the original assemblies to get to the screws.
We have not experienced any electrical problems with flashers or the like. We just plugged them in and they have worked properly for about 2 years now.
The LED replacement style for the Deere tractors is fairly expensive but is the route to take in my opinion.
Some other older vehicles that use the old style "flashers" could be a problem. The old flashers work on the principle that the bulb creates an electrical load which causes a set of points in the flasher to open due to the heat developed. This breaks the circuit until the heat dissipates and the points come back together and once again complete the circuit. This movement of the points causes the ON/OFF or blinking action.
If a signal light is burned out, the other light might still blink but at a slower rate. If a trailer gets involved with signal lights of its own, the electrical load is greater and the flash rate may be faster.
With those systems, if a single old style signal light is replaced by the LED style, the electrical load of the LED may be much less and the flashers might not ever get "hot" enough to cycle.
Modern vehicles don't use the old style "get hot and open" approach to flashing the lights. Commonly a microcontroller is involved that triggers the circuit based on time rather than electrical load.
