possibly they realized that barely anyone gets halogen models now (nightmare), because the Led and HID (which is no longer advertised for) "are so much better" and had to offer a lower priced model.
The missing customers for the holgen are quite numerous and bring the money, Wilma/Betty/Edison sales alone dont cover cost.
Aside from some specialists not liking the P7, the tesla seems to become their cash-cow light now (when it will be purchaseable).
(unfortunately the buyers are tricked, even when it is "cheap" - compared to the other offerings.
f.e. the head alone is argued to will be offered for ~ € 170,-- --> making the batt pack pretty much the same price.
Now we all know the manufactoring cost for such a complete head to run around 70-100,-- (I tend to 70 at max), but the batt pack?
Must be a pure 150,-- of net earnings.
Thats real economic genious!
(and the converts pay it)
