I did a projector and HID retro fit on my car and I was wondering about the beam pattern and lenght of travel. It seems to go on forever on the freeway it lights up 5 lanes and has a sharp small thin rainbow effect at cut off line .Did I do something wrong or is this right ? I have no glare when looking at the headlights and have not had anybody flashing there highbeams at me when driving.

 

What projectors are you using? Post some pictures.

 

the rainbow effect is normal.

There is a way to adjust your headlight to the right height, but I'll need to find a picture. If someone has it, please post it. It'll save me some time

But to 'quickly' check to see if your headlight is aim too high or too low, drive parallel to a wall and see if the cutoff beam is angling down or upwards.

 

It is level, that is how I adjusted them.

 

Hellas is what I used.

 

Then you're good to go

 

Level doesnt mean they are aimed correctly.
