I have a John Deere GT225 garden tractor. I bought it new a number of years ago. While I don't operate it all that much after dark, the OEM lighting is pretty mediocre. It would appear that the OEM bulbs are simply 1156 incandescent bulbs. I know that there is, or at least was, a quartz halogen kit with heat shields more more lighting. I am interested in using LEDs. What are some of the LEDs that have a good number of lumens that I should consider?
