Does anyone know if you could aim 04-05 headlights outside of the car by placing it on a flat level surface?

Would the way the headlights are sitting on a flat level surface be the same as the headlights sitting on the car? Or would they be angled differently?

u gotta aim them while they are on the car

basically if you take them off and put them back on your most liukely going to need to aim them again as it will be off a little bit

Let's say you could power them off the car... if you had a perfect horizontal line while the headlights are mounted to the car, and u took them off and put them a surface parallel to the floor instead and shined it on the same wall, would there still be a perfect horizontal line?

just wondering so I could figure out if i could aim hid projectors in them without them being installed on the car.


In that pic, there are little pegs on the bottom that make them sit they way they do on a horizonal surface. I'm not sure if they're mounting points or not. But maybe they're there so you can aim the lights without them being on the car?

you have to have them on the car and there are adjustment screws on the backside...get a philips screwdrivers and you will see a little knotch...turn the screwdriver right to make it point higher and left for lower

if your doing a retrofit you want to align them when there on the car. The most important alignment is the rotational. If your rotation alignment is off your beam pattern won't be that wide. Everything else is relatively easy to fit. But trust me, you wanna aim them with them on the car.

Are you sure that's the only way to get a proper alignment? I'm just worried about rotational alignment because I don't want to drill extra holes if it turns out crooked.



Is there a way to get perfect rotational alignment by looking at the oem reflector? In that pic, there are two horizontal lines on the reflector... did you find that with your retrofit, your projector shield lined up with those lines?

you can try using the lines, but you want to mount them on the car before you finalize it. On my e46 projectors i tried to make the opening of the projector as flush with the back stock opening where the stock bulbs plugs in. I also used the dot line on the lense of the e46 to give me an idea on the rotational.

I mounted it on my car and made minor adjustments to try to correct the rotational. Its still a little off though.
