I bought mine from Lights4all a few years ago and they do fit my (donated by a forum member) Vaq turn signal housings without any issue whatsoever... I wouldn't imagine they've changed them at all, and you're right - they warn they won't fit the Vaquero on their website. That looks very much like a mistake on their part though... Their Ebay store listings show:
"Kawasaki VN 1700 Voyager Custom, 2011 - (Nicht passend für VN 1700 Voyager!)"
Which makes me think they meant to say it won't fit what the rest of the world calls a Voyager?
It’s not that they don’t fit, they fit fine, you just have to put the left one in the right housing and visa-versa like I described. If the cast printing on the face of your lenses are on the inside of the bike closest to the headlight or tail light and not outside of the turn signals, then you already unknowingly put them on the way I described. You will also noticed they have an “R” for Right and an “L” for Left with that writing on the lenses.
Yes, as I mentioned, nobody makes them for a Voyager at all, they call a Vaquero a “Voyager Custom”, and for some reason, the Voyager Custom uses different housings for the turn signals that look identical but clock the lenses differently, that’s why you have to put the after market lenses in the way I described. You will also note that even in your own quote of their eBay ad, they do not mention at all that they fit a Vaquero.
I see you are in New Zealand, do you guys even get a Vaquero there or is it a Voyager Custom? In America, we don’t get the Voyager Custom, we get the Vaquero. Apparently there are small differences between the two, like the turn signals. It’s no mistake on their part at all when they say it won’t “fit” a Vaquero, as mentioned, it’s because of how the left and right lenses clock in the housings. The reason why there are even a left and right lens is because of the drain in them, it has to be at the bottom.
I contacted them to let them know they do work if you swap the lenses side to side, but they can’t exactly sell lenses that are marked Left and Right and tell their customers to just ignore that and install them in the opposite housings, they can however tell people that others have done that if they email them and ask if they will fit a Vaquero like I did instead of just flat out saying “No”.
The main point of me posting was to show people that these lenses do fit, even though the sellers state that they do not fit.
