I didn't put much thought into the before/after pic location. it doesn't show much other than the fact I adjusted my headlight up some...yes it needs to come up some more. one thing the pics don't illustrate well is the difference in how the harness lays light on the road. I can tell a major difference how the light lays on the road now AFTER the harness, it is much better. there is a much wider area covered and it is lit up better. the light is obviously much brighter in the after pics. I used an iphone5 hd setting for all of them.

I feel the harness definitely made a difference. the end result of how the lights work is undisputable. they work much better with the harness in place. anyone on the fence or just curious, this is a worthwhile upgrade, even for stock-style sealed beam lights. hope this is helpful.

 

Thank you for the review and the excellent pictorial. It really show the difference.
An upgrade that works!

 

Probably worth mentioning that when coupled with a H4 headlights replacement, the results are even more evident...

 

want to update the thread with some pictures of the install. I think it looks fairly clean. I ran the harness underneath and it basically lays in the lip on the bottom of the rad core support. I ran both sides up between the bumper and inner fenderwell, right up to the back of the headlights.

from the top, this is all of the harness you can see. I ground this side on the bolt right next to the hood latch spring dealio.



this is what it looks like from the bottom

Looks like a factory install too good job.
