Fellows, I contacted Snapper Pro and they looked up my serial number and they had on record my headlight purchase.
The tech support told me that the dealer ordered the wrong headlight assy.
They sent me a copy of the catalog page that had the correct number and the sheet that showed the complete installation, and they did all this within a couple of hours.
What great tech service, I have never seen service like this especially in these troubled times, I even feel better about getting a Snapper mower.
Hat's off to Snapper!
Sincerely, Ron
