It's a sans serif of some sort. It is on the lens of a Whelen M7 Lighthead, the most visible text is on the lower left, right, and top right corners. Font is used on the lenses of other Whelen lightheads and products too,

The most distinct features I am noticing are the sharp angle on top of the 3, the middle line on uppercase E being shorter than the other two, and the uppercase G being fully rounded on the outside.
Use is recreating this same lighthead as a 3D model.
