Well, my install is not H4, but since you mentioned Hella and Ecode lights,..... Figured I would chime in. My install was a Hella HB2/9003 bulb and lens kit. This is a common bulb, and if you look at the bottom of my link below, you will see the light pattern in the dark - pretty good I think.
I'm in central MD, and the cops are strict on jeeps. The non-E code lights were all I had a choice of. Since Hella was highly rated here on the forum, I took a look at them and bought them. Here's my install.
If you want another picture of light distribution at night down a long road, I think I can accommodate. Just let me know.
Best of luck!
