Dude...the bulb just comes out of the socket you didn't have to buy a whole new one. Just get two socket 3157 switchback LEDs (3757 is exactly the same except amber). You'll need the
switchback bulbs and a pair of
load resistors (those links are taken directly from my order review).
Now, once you get them, wire the load resistors from the light blue wire on the harness to the black wire on the harness (wire taps are also necessary) then just zip tie the resistor to the wiring to keep it from swinging all over the place. Repeat for the other signal, and you're done! You now have pure white running lights and nice amber signals with no hyperflash.
