If I had access to the Holleys, I'd gladly do a side by side test. I did a lot of comparisons between the Grotes I purchased and several other brands of LED headlights for my use.
Comments on tests-
1- Shining lights on a wall 20' away is a great way to make any quality of light look decent.
2- pics of how a light works on city street is essentially worthless also. You need a dark street or country road so the only light in the pic is from the test light.
3- comparison pics btw different tested lights so if you only test one it looks good because you haven't compared it to a great beam pattern showing light intensity & pattern.
Anyway, just some random thoughts. There's a few of us that daily drive on County roads so actually having a great beam pattern is more important that how it looks so without street lights and having deer jumping out from the ditch sides or from behind trees several times week (damn critters!) Is extremely important. lol
Just some thoughts is all.
I know 95% of the guys with restomods in our club, hot rods& Broncos, never and I mean never drive at night so looks (like a great paint job) is their highest priority.
