Is this one what yours looks like??
1994 Winnebago Elante 33 1/2' Class A Motorhome
I Am Not sure what vehicle that headlight is from. But I'd bet it is from a Ford.
Look close at your light lens for a Ford number.
And when you do find it it wouldn't surpeise one bit if For has discontinued it as well. But don't worry You will be able to find one on ebay and other places if that happens.
My guess is its definitely from a Ford
Just for reference here are the winnebago part numbers
095213-01-000 EA HEADLAMP-PASSENGER, W/TURN SIGNAL LIGHT
095213-02-000 EA HEADLAMP-DRIVER SIDE, W/TURN SIGNAL LIGHT
Why these RV companys can't tell you what vehicle they are from after they WON"T sell them to you irritates me
