Well I do much of my driving during the week when it is dark out. I have owned my JK since last December and I have really been wishing I had a bit more light. Not wanting to use my fog lights as crutches all the time. So I did some reading on the forums around and the best bang for the buck I found was to just replace the headlamp light bulb. I went with the trusty SYLVANIA brand. Not that they don't already own most of the market already, LOL. I put in H13(9008)ST in the 2011 JK and what a world of difference.
