I replaced my oem tail lights with a pair of boat trailer lights (with the clear bottoms ) and they help light the area when backing up ,especially bright if you touch the brakes a bit. The extra light they throw while in park even helps when you are closing a gate behind your machine. Mud will cover the clear bottoms though if you are in muddy conditions. I had them on my '05 and liked them so much, that I swapped out the oem from the new 2011 to the '05 when I sold it, and put the boat lights on my new machine. An oem back up light would be real handy . This is an old issue I wish Kubota had addressed with the improvements. bordercollie
