I have seen how sketchy the LED lighting market can get and that alone is a good reason to go with the dealer. At least for one its a reputable source and if you come across problems in the future getting it resolved will be easy.
I was thinking about it as well, but I am opting for aftermarket LED lighting in my fog lights. As I understand, it's just the bulb they're changing out and the housing is the same. There are several contenders (available on Amazon); all with good reviews and warranty.
I have 2020 Qashqai. It is the SL Platinum package. I was very dissapointed to see that the bulbs in the fog lights are not LED and therefore not as "white" as the headlights. I asked my dealer about changing the bulbs and he told me that the bulbs could be changed but some other thing would have to be changed as well so as not to "burn" or "short" the system. Anyone else heard of this?
