Okay, so I've been collecting interior lights for the past year and have been thinking of doing this for a while. So some of you may be irked by my next statement, but it is factual. There is truly no such thing as a Porsche 914 interior light. All of these lights carry a VW part designation and the VW light was already in mass production before the first 914 was ever built. But, I see the topic come up from time to time as to which light is for a 914? All of these lights can be used in a 914 application, some with a minor mod electrically speaking, others are plug 'n play.
The light which is branded "Hella", "VW", "Made in Germany" with a white square button and chrome edge is the one typically found on 914's imported to the US market. The Sidler light was also made in Germany and Saturnus was made in Yugoslavia. Hella later acquired Saturnus and is now known as Hella - Saturnus. All of the lights below, to my knowledge however, are authentic authorized OEM VW parts. So, if you need to be period correct, you would get a white square button, chrome edge light. If you just need to be able to see in the dark, any will do just fine.
BTW, there are other lights out there, but they are typically aftermarket, non-VW,
non-OEM reproductions.
Let the debate begin...
