LEDs make a huge difference! Not sure why Kia cheaped out here when they have some many LEDs elsewhere.The stock reverse lights are standard incandescent, dim, and give off a yellow-ish tone. For me they didn't do a very good job of illuminating the area behind the vehicle. I therefore upgraded the bulbs to LEDs and it has vastly improved the visibility. You can search on here for product recommendations and directions for replacement (videos and pictures galore).
I will look into the LED lights, but even the regular ones are a HUGE improvement over my old MDX from the factory. I had an LED light kit installed at a 4WD shop so I can out the back at night.LEDs make a huge difference! Not sure why Kia cheaped out here when they have some many LEDs elsewhere.
