I use the original-option style side-lights/lamps for brake/driving/turn (now with 6v dual "filament" LED lamp/bulb) and the original lamp on the rear driver's-side door with a 6v dual "filament" LED lamp/bulb (brake/driving "lamps"). Much brighter than original 6v bulbs - as bright as 12v LED bulbs.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
