This weekend I also replaced my front grill from silver to angry black. And swapping out my factory headlights for some nice LEDs.
The grill was simple to remove and head lights and turn signals were easy to remove as well.
6 little tabs along the top of the grill just under the hood pop right out with a flat head screw driver. Then the bottom of the grill you can just yank straight out as the connectors aren't too strong. Just don't bend them up or down, but pull straight.
You also have to disconnect the turn signal or unattach from the grill as the turn signal housing is connected directly to the grill by little tabs. I found it easy to just unplug each signal then take the signal out of the grill after it was completely disconnected, but you could also leave plugged in and take out the light or bulb as well.
Factory silver grill and lights before and after
I am really happy with the LED lights. HUGE improvement in lighting and looks.
The lights were simple enough to install but as my 2012 jku doesn't have DRL, I couldn't figure out how to wire the Halo part and there is also a feature where the halo's will connect and flash with the turn signals, but wasn't too concerned with that feature or exactly how to wire so I will save the DRL and turn signals for another day.
Pic of box but not sure why there is another light on right side as mine is the left one.
