Moto Guzzi never produced a spot light. Instead, they provided spot light brackets (for police use) which permitted individual police departments to fit spot lights of their choosing. A popular choice by police departments was the Dietz brand of spot light. Specifically, their 9-51 model spot light was approximately 5 1⁄2 inch in diameter and 3 inch deep. It accepted General Electric bulb style 4001 and could be of a variety of colors (e.g., 4001-R for red). Dietz has long been out of business (first bought out by Federal Mogul, then by Truck-Lite).

A good replacement for the original spot lights are these 4 3⁄4 inch spot lights and bulbs sold by JC Whitney (thanks to Charlie Mullendore of Antietam Classic Cycle for making me aware of these spot lights). Note that the housing/body and sealed beam lens/bulb are sold separately.
