Well. Here is the respond from Vlad.
"Well, I am glad to have such feedback from customers! Basically this is the first time we are selling them for NBFL, means the market are mostly the NAs. They are not having the interior light in the middle, thus, we need the long cables to make it universal fit. Then, comes the next point. Although it is shorter to connect to an interior light NBFL has, it is not professional to sell something, where welding in a car is involved. I guess many guys will still prefer the connection down, other than cut and weld."
