Default Morimoto headlight adjustment

Just purchased these from vette lights and I need to adjust as the height projections do not match up on both. Does anybody have tips on what type of wrench to use for adjusting the headlights? I see the brass colored bolt thru the small hole (when you remove the plastic cover thing) but it is very tight to get any tool in there! The 3/8 socket wrench head will not even fit in the hole. The 1/4" socket wrench will fit but it is not long enough and even then I cannot get the angle to turn the wrench. Also, if someone can confirm the bolt size? Any advice would be greatly appreciated.

I suggest returning them when you have time. The LED emitters they are using are weak, and the optical design is middling. And as you found out, the quality control is lacking. I've analyzed several pairs of their headlamps and found tremendous variances between samples--much bigger variances that I'd expect from a pair of OEM headlamps.




The size of the bars in the below chart represent the amount of variance in luminous intensity for various headlamps. Morimoto's are all on the left half of the chart. OEM lamps are on the right. Note the much smaller variances (smaller bars) present across various OEM lamps.

That's some good data. Do you do this analysis as part of your job or just for fun? As someone who likes to play with Excel spreadsheets I can see where it would be for fun but how do you get so many samples to test? Just curious

Not sure how you get your info but I had the C6 Morimoto lights and they were almost twice as bright as OEM. I blinded everyone in front of me.

It's a Phillips head screw. Nothing special.

After reviewing the charts in more detail, the Morimoto have more variability overall, but they are still brighter overall about 80-90% of the time. Plus, there is no evaluation for c7 stock lights or the Morimotos for the c7. Not sure what you're trying to prove as this data doesn't apply to the c7 or the Morimoto lights for the c7.

How would you compare the brightness of the stock lights vs the Morimotos?

I'd say they are pretty close to one another. Now if I can figure out how to adjust them!

I found them to be brighter over the stock lights and they project light further without blinding oncoming traffic when adjusted properly. As mentioned in your other post, I have had success using a flat tip screw driver using it to move the serrated portion of the adjustment. I still have some fine tuning to do and will let you know how this tool works out when it comes in.

​​​​​How are you using this when the correct tool is a phillips head screwdriver?

From the engine compartment I just move that piece that looks like a gear with a flat tip. How are you using a philips head screw driver?

The phillips head fits into the hole and you just turn the screw.

I don't think we are talking about the same adjustment screw. There's one that you can get to by moving the fender liner away and put a phillips on easily and another that is accessible through the small hole in the engine compartment which a typical phillips wont fit in.

This thread shows the hole in the engine compartment and position of the oem headlight adjuster.

I'm wondering if the oem adjuster can fit on the new lights. Does yours by chance look like the one in the pictures?

Correct. According to vette lights there is only one adjustment screw which is visible thru the small hole in the engine compartment and a typical phillips wont fit! That is what im trying to figure out. Maybe a short video will explain better.

one for up and down and the other for side to side. I suppose it is possible they only intended for the other one to be used but there are most definitely 2 adjustment screws. I’ll do a video or something on it next week to show y’all how I get it done.

That would be great. How are you supposed to access those screws?
