Question:
Good Afternoon to you, i bought a ceiling light to replace in an 03 model, am wondering if i had bought the half inch smaller light if the screws would be located narrower, as my old one is a screw pattern- only one screw at lateral ends. If you’ve happened to seen or worked on these things. Thanks.

Hey Cortney,
The Optronics 12V RV Dome Light # RVIL22 you purchased will have at least the same dimensions, if not closer together, than the Gustafson 12V LED RV Dome Light # 277-000340 you're looking to replace it with.

Hey Cortney, how did the fit go with the Optronics dome light compared to your old one? It’d be great to know if the screw spacing lined up the way you hoped. Your update could make it easier for the next person replacing a similar light.
