2014 Summit HIDs Blinding Oncoming Traffic
 
Hey Folks,

I've read a bunch of threads here on the forum about the HIDs blinding oncoming traffic in some WK2s. However, I haven't found the answer I need to fix the issue in terms of adjustment height (in normal mode---not Sport).

It has been my "simpleton" understanding that you back a vehicle 25-feet (or 33-feet in some vehicles) away from a wall (on level ground sitting in it) and measure up to the top of where the headlight beam line cuts off. That beam should cut-off at about 3-feet. Am I wrong? Is it 25-feet for the Jeep or 33-feet?

I get flashed by oncoming traffic constantly going to work in the early AM. The dealership says all kinds of funky things like "the bulbs are new and have to age" and "are you accidentally using the high beams?" etc etc.

Yes, I know:

1) The HIDs are adjustable from the screws in the top with a long phillip screw driver.
2) When you drop it into Sport Mode it lowers the beam.
3) The lights are "supposed" to adjust automatically (and they probably do IF the beams are aimed correctly to begin with).

I have read this: http://www.coolbulbs.com/HID-VISUAL-...-PROCEDURE.pdf

But it does not state the Height that the light should be.

Any ideas on how high the beam should be on a wall if I back the vehicle 25-feet away? Mine seems to be coming in at around 4 to 4.5 feet from the ground.

Sorry this does not help you with the exact measurement but I just experimented with mine to find a height that provided plenty of light on the road without blinding other drivers. Mine were set high enough that when I drove in Normal mode at night I would light up the entire interior of the car in front of me. So I backed them down a few turns, went out at night to see where my cutoff was and adjusted from there.

It only took two adjustments to find the "sweet-spot" so to speak that provides plenty of light in Normal, acceptable light in Sport and which does not blind others.

Also I'm not sure if those measurements completely apply to a vehicle that has an adjustable suspension. I found that if you have them aimed a little too low and drive in Sport mode the beam does not travel far enough down the road. YMMV:thumbsup:

Hey Berk...thanks.

Well, the lights will adjust as the vehicle's height goes up and down---I tested that on the wall in my parking garage this AM. The cut-off with mine seems to stay the same---right about 4 feet from the ground to the top edge of the beam. I just think that mine are aimed too high to begin with as mine seem to be doing EXACTLY what yours did to vehicles in front of you.

You actually did help. Question---to drop the lights did you crank it clockwise or counter-clockwise? I'm just going to crank mine down about 4-inches at 25-feet and see how that goes.

Regards,
John

I think it's clock-wise to drop. If you leave them on when you adjust the screws you can watch the beam drop and make sure you are going the right direction.

Yea my lights adjust as well when I change the suspension height, I watched them on a wall as well, but it seams like the beam travel is not the same out on the road. maybe something to do with an incremental angle change between Sport and Normal. Oh well, it doesn't matter I've got them just right now.

Good luck with yours.
Berk

The light beam should slope down. Measure from the center of your headlight beams to the ground AT THE VEHICLE. On flat ground 25 feet away, the upper cutoff of the pattern needs to be lower than the measurement at the vehicle. If its more, your headlights are aiming UP and you will be blinding oncoming traffic!

Just adjust , drive around the block, adjust, drive around the block.
Then when you get it looking correct, stop. If over the next few AM drives to work you still get flashed, adjust.
You are making this way to complicated.

Can't argue with that technique! Also, if your gonna eyeball it when adjusting, look at the pattern it throws. Try to get it to illuminate the ground on low beams as far out as possible without it getting dimmer. If you can find a dark level lot or safe road, its easier.

Hey Guys....took it to the dealership again on the way home and the lead mechanic offered to put it on some kind of device that measures the light alignment. I agreed! Anyway---5 minutes later they had a lead tech adjusting the lights. They never admitted that there was an issue---but the guys pulled it up against the wall and showed me that they cranked them down quite a bit.

So yeah...some do come from the factory aimed high---they won't admit it openly but this is not our imagination. They also offered to dial them down more after I drive it for a week and test it out.

Thanks for the replies.

By making the adjustment at no charge, they admitted it. :thumbsup:

Not sure why you would go spend all the time and effort to have the dealership deal with this when it can be fixed by you with a screwdriver in less than 5 min.
But to each there own i guess.

Thanks Bill---I tried to make the adjustment myself but didn't have a philips screw driver long enough. I dug through my tool box and had 15 flat head's but ZERO philips that would reach. I figured it was cheaper to swing into the dealership than to go buy another screw driver. It was free and took 5 minutes. I spent more time posting that it took to fix it.

Anyways...thanks guys.

Gratz on the CIB, sir!
