Blind them with science, not your lights! ☀️☀️
I recently drove my 4 runner at night for the first time after installing my new Alpharex Luxx G2 headlights and I couldn’t see a thing. And I’m pretty sure oncoming cars couldn’t either.
My light beams were way too high and I was getting no light on the ground. So I went home right away, checked out the
@runnin4tacos install video, and contacted
@alpharexusa to ask some questions. Here’s what I found out.
According to the
@runnin4tacos YouTube install video for these lights, you should take a measurement from the ground to the center of your headlights. Mine was 44.5 inches. Subtract 2 inches to get 42.5, and that’s the height in step 1 of my reel (The desired height of your beam cutoff at 25 ft from a wall).
When I messaged with
@alpharexusa , they suggested the cutoff should be at 40-41 inches.
I decided to start with 41.5. (Between the R4T-based reco of 42.5 and the Alpharex reco of 41-42).
* In step 2, I measured 12.5 ft from the garage door. Why did I use 12.5 ft? That’s what I have available in my driveway and I wanted to be able to come back to that location for testing. It’s also half of the 25 ft recommendation. So, if I want my cutoff to be at 41.5 inches, and my headlight center is 44.5, math suggests that at half the distance, my beam cutoff on the garage door should be half the difference of 3 inches (44.5 - 41.5 = 3 inches divided by 2 = 1.5 inches), which puts it at 43 inches (44.5 - 1.5 = 43). Make sense? I think it’s harder to explain than it is to understand. Ha.
Once I had my beam cutoff level at the tape line, Steps 3 and 4, I made sure both beams were level (step 5). I then went and tested it (Step 6). During the test it was much brighter than it was prior! I think it still needs some adjustment, but now I have a process I can control in my own driveway to try different adjustments.
