We all know the stock JK headlights are an embarrassment. So one of the first things I did was replace them with the infamous (and oft used) Trucklite LED headlights. But as the technology has improved in the space, I never thought to see what else might be on the market, or what the improvements could be.
UPDATED 10/8/2014 with a very important update! Even though I applied this fix to my battery terminals, there must have been a very tiny gap that remained between my terminal and the battery post.
On a recent offroading trip, I was winching another vehicle and the additional strain on the battery caused a spark to arc and actually fused the terminal to the battery, causing battery failure. The ground winch cable was too hot to touch. I was lucky to get out under power and make it home. It remains an expensive fix (the OEM battery was only a year old) but if you are stuck in the woods, the costs and risks increase. Based on the temperatures, I would not rule out a fire risk. Please REPLACE your terminals immediately to prevent you from getting stuck, or worse.

The forums are ablaze with questions around concerned Jeep drivers, that their gauge cluster will suddenly light up, chime, and do some weird things – but only for a second or two.
I found myself dealing with this exact same problem in both my 2012 and 2013 Rubicons (the videos above are mine). Taking the 2013 in under warranty, the dealer was just as perplexed as I was. Eventually they changed the electronic sway bar disconnect motor (claiming it was not sealed for water and thus causing the short).
