If plate is in one piece, you can replace just the light part.
Or remove light and shave down remaining stalk base off plate. Bolting flattened plate back onto fairing lets you use many aftermarket lights with backing washer under plate. I've even used rear turn-signals from my VF500 on front of pre-gen this way.
