Short story: I put in an H4 wiring harness and lights with 100/80W bulbs and it was a huge improvement. Less than $200 invested. But I kept breaking headlight lenses for some reason.
This time I was considering biting the bullet and going with J.W. Speaker. I'd compared the JWS to my H4's and the J.W.S. were a bit nicer light pattern and a bit brighter. Not 3x better to match the 3x price, but since I was replacing my H4 headlights once a year due to breakage, I figure the J.W.S would pay for themselves in 4-5 years plus save me from needing to fuck with the headlights every again.
But while searching for deals I came across Chinese clones of the J.W.S. for around $200. Good reviews. I figured I'd give them a try. Have had them for 2 months now and I'm satisfied. They have a weird, square hotspot in the middle of the road. But that hotspot actually works out well for illuminating distance. They also have halos with turn switchback function so I can pretend I'm a ricer while driving the Jeep.
We'll see how they last, but I feel like I've got my money's worth.
