Newer is a relative term, but years ago my parents had a late 60's or early 70's travel trailer that had both 12v and 120v bulbs in the same fixture. They had 2 switches on the fixtures. If you want to get technical, some even older trailers had gas lighting so it hasn't always been 12v.

So if you want to be so inclusively "technical" why not go back to the stage coach days and include lighting systems used then?! Be real ... the OP has a ~ 10 yr old travel trailer and simply wants to know where / how to best pull 12 vdc for a radio so of course even the suggestion that his interior lighting could be 120 vac is totally ridiculous. :W

Allow me to mediate----the post that had reference to 120V lighting, the phrase "newer" pertained to being inclusive of all ages and was referenced in that manner. The follow up post explained the inclusion of 120V and various ages and types of lighting, in reference to your exclusion of any trailer having 120V lighting. There is no ridicule involved here nor should there be.
IMO, you are showing a pretty thin skin in this matter.
