Yeah it is but from my understand sounds quite good.
edit: update, the unit in the photo appears to be missing the cover to prevent people from getting their hands on it. Protection if you will.
The model is a gates m-6144
Here is a link to the manual with schematics...

Hi, I just got one of these, but it didn't come with the on-indicator lightbulb. Does anyone know the model of bulb that this needs? It's not a bayonet type.
Thanks.
