I didn't have to do anything to the car as far as dropping the bumper or moving any part under the hood. Once I saw for myself where the low beams were located and how easy it was to access them, I pretty much knew I'd be able to do it this way. And I have big fat boy hands but it still wasn't that bad. Dust covers off, old lights twisted off, new lights twisted on, done! The little diagnostic plug bracket scraped up my hand a bit, but that's better than doing it any other way in my book! I bought Lasfit LEDs by the way, no affiliation I promise, just putting it out there since they are specially designed to fit the Hyundai/Kia bulb holder. Went right in without a hitch and they fit nice and tight.
