Q: Does an outdoor diesel-fueled generator need a light fixture? If so, does a flashlight or wired fixture meet that standard?

A: Yes. Section 7.3.2 of NFPA 110-2010 does discuss the need for “normal service room lighting,” which is required to be at least 3.0 ft-candles. And while section 7.3.3 does require emergency lighting in outdoor units, it does exempt emergency lighting in outdoor units that are not designed to be “walked into.” But NFPA 110 is rather strong on this point and does say in the Annex section of 7.3.3, where units housed outdoors are used, it is recommended that a flashlight or battery-powered light with a flexible cord be maintained in the housing.
