How much difference did they make, I'm considering changing all my bulbs to LED.
I read good reviews about StreetGlow XHP LED Headlights in another Jeep forum.One of the first things I discovered was the headlights (specially the high beams) were lousy at night. I first tried replacing the standard bulbs with Sylvania Silverstar Ultra's. They were better than the stock ones, but I needed brighter high beams at night to watch out for deer. I then bought a set of LED bulbs from my local performance shop...StreetGlow XHP LED Headlights. They are a plug and play bulb that put out 6000 Lumens (brightness) and a color temp of 6500K. They cost me around $175 for the pair....a little pricey, but they will last a long time. A standard bulb has a 800 to 1000 hr life where the LED's are rated at 100,000 hrs. What A Difference!
