To answer all the questions...
Autospark - I was using these resistors:
50 Watt 6 Ohm Load Resistor
Tiger-Heli - I tried the parallel once already, and it didn't work. Thanks for the idea though.
GreyOwl - I know how to wire them, I did the rear ones just fine. The problem with the 13 HSH is that the front lights are a "plug" type, that can be completely removed from the car, without wires on it. You twist, pull, and the entire light and socket comes out of the housing. There are no visible wires in that area to put the resistors on, unfortunately.
MButkus - Because I wanted brighter, cleaner, lighting on my car? The tail lights (brake and side markers) were already LED, I changed the license plate bulbs to LED, the turns to LED, the trunk light to LED, the glove box to LED, and the dome/map lights to LED. Why? I have always done it to my cars (since 2009, when I owned my first car). They flash brighter, are faster response time (instant, compared to the "delay" of incandescent, and yes, fractions of a second matter sometimes in situations where someone needs to be alerted faster), and they look better on the car. Also, my Scion had a "flash controller" that I could buy and switch out (the thing that clicks behind the dashboard) instead of load resistors in that car. I couldn't find one for the Sonata, otherwise, I would've just went that route. I also have blue and red LED strips inside the foot wells and under the front seats to illuminate the interior. Why? Because I like it. Are you going to tell me that that's wrong, too?
Tiger-Heli - The sonata doesn't have switchback, unfortunately.
