Considering the price, Nokya bulbs are by far the best bargain we have available for your F250 fog lights or headlights. Sylvania are very pale color-wise (even worse than PIAA), Luminics have an overall higher defect ratio, and most other brands do not stack up to Nokya quality (let alone PIAA).
Winjet is about as close as F250 Foglights get to having a “name brand.” The quality is a bit better, and they usually install easier as well. Also, unlike X3 F250 Fog Light Kits, every Winjet F250 Fog Light Kit comes with wiring harness and fog light switch (universal style in some cases), even for models where the vehicle should already have them pre-installed. This makes Winjet a perfect choice for people looking to make a clean installation on their vehicle that have harnesses that might be missing or damaged.
