First mod I did (not cheap) was swap the pathetic stock head lights for some TruckLites.
First thing I did the day after I bought my Rubicon was take it off road and mangle the crap out of the driver side of the bumper so I had to buy the stubby bumper end caps, then a light bar, then lights and all hell has broken loose.
