You now have your new IPF H4 headlights.
I found the look of these headlights to be rather retro. They look more like an old-school sealed beam headlight than a fancy pants upgrade. These headlights don't announce themselves as an aftermarket light.
The color of the light produced by the IPF H4 headlights is closer to the color of natural light, and that makes it look slightly more blue in comparison to the factory headlights.
The light color is on the factory headlights is yellowish, and the pattern is apparent on this close-range picture. The light is produced in a solid "bar" through the whole width.
The IPF lights have a more natural blue tone to the light, and the E-Code pattern is more sharply defined. Notice the kick up on the right side of the light pattern.
These headlights did not carry a DOT stamp (that I could find). They are, however, E-Code stamped, which is the designation for a European standard headlight. The pattern of an E-Code is generally understood to be sharper with a more defined upper cutoff than a typical DOT headlight.
If you live in a state that has very strict vehicle inspections, they might give you trouble if they can't find a DOT stamp. This is just something to think about.
Aiming the headlights is a fairly straight forward process, and there are good resources on JKO as to the process. The IPF headlights had to be aimed a good bit higher to get what I felt was good coverage. I have not had anybody flash their brights at me thus far.
IPF H4 Conversion:
Notice how the factory pattern doesn't even show up on the ground until quite a distance from the front of the Jeep. The IPF lights, by comparison, put more light closer to the front of the Jeep. Initially, I found the light being closer to the front of the Jeep to be more distracting than the factory lights, especially with the brighter output.
The factory lights put more light off to the sides of the road than the IPF H4's. The IPF lights have a pattern that is "straight ahead" compared to the factory lights. I found the IPF lights to be lacking in tight turns on dark roads, there wasn't enough light cast to the sides to illuminate the road. I particularly noticed this in neighborhoods with 90-degree turns in the road.
One can tell by the stop sign in the distance that the more natural light color combined with the pattern of the lights sets off reflective surfaces far better than the factory lights. This was one thing about the IPF lights that I particularly liked.
Living with the IPF H4 Conversion:
Initially, I was not very impressed with these lights. The lights had a far better color and brightness than the factory lights. However, the light being cast so close to the front of the Jeep was very distracting to me. I don't normally drive with the fog lights on, so those who do might not have a problem with this pattern. I didn't like it.
It seemed like I had to keep aiming the IPF lights higher and higher just to get them to put any meaningful light down the road where I felt it would be useful. I drove this Jeep and another Jeep (with stock headlights) back to back, and I felt like I preferred the stock lights. It was hard to believe that was the case.
It took me about seven days of driving with these headlights before I started to come around to the IPF lights. I was driving down a two-lane blacktop with no street lights, and I realized that I was actually seeing the road quite well.
These headlights seem to be better suited to highway driving. The beam projects dead-straight, with little to the sides. Road signs and lane markers are far easier to see and read from greater distances than the factory lights. The high-beams are aircraft landing-light bright. I grown to like the sharp cutoff of the E-Code beams, and the limited light being cast to the side of the road doesn't seem as bad as I originally thought.
My main concerns with these headlights were mostly with fitment. The housings did not fit into the Jeep particularly well, and the bulb-end of the adapter harness did not inspire confidence. The look of the lights is old-school, and I haven't really decided if I like it or not. The pattern of the lights really boils down to a matter of preference. Overall, I was not blown away by these lights. I can't really be sure if I'm seeing the road any better, or if I've just grown used to them. There was not that "wow" factor one would hope for with an upgrade to better lighting.
