I was just wondering if anyone knows why the lights on the jk have covers over them, notice light are dim and going to try to take caps off

 

Can you clarify what you mean by covers? Are you referring to the reflector that is on the inside of the head light enclosure? If so you do not want to remove that.
Just replace the bulb with a silverstar or something brighter and call it a day.

 

I was actually going to ask about this. I find the lights quite dim in my 2011 JKU, any bulb suggestions out there?

 

HID's would be your best route.

Had them on my last car and it was great, but won't be upgrading to HIDs with the Jeep. I think I am the only that thinks the light output is fine.

 

I don't have an issue with the stock output either. So that makes two of us

 

Sylvania H13ST bulb is a lot brighter than the stock bulb.

The problem then is the fogs. If you replace the headlight bulbs they are whiter than the fogs so now the fogs will look on the warm side (yellowish). Unfortunately due to the wattage of the fog lights you are pretty much stuck with getting an LED upgrade such as http://www.ebay.com/itm/HID-White-68...-/170693551455
