I20N headlights
- Thread starter tc222
- Start date
Based on your avatar photo, I believe you own an i30N model, whereas this thread was discussing the headlights of i20N cars.
Hyundai i20N and I30N models have full-LED headlights (so no traditional bulbs), but the design of the headlights themselves is very different. Adjustment of the headlight aim is covered in the Owner's Manual and the two attached drawings show the design variation.
Although the Owner's Manual guidance on adjusting the aim of the headlights is identical in both cases, the headlight design difference almost certainly explains the confusion over whether there are 3 screws (i20N) or 4 screws (i30N).
Ok - I see that you have now changed your avatar to show an i20N.
I still do not understand your earlier question "Does anyone know what bulbs he has and if there are better ones?" as the headlights of an i20N are LED type with no bulbs that can be replaced. (Example of i20N headlight here).
The only i20N front lights with incandescent bulbs are the fog lights. These use a HB4 bulb and these could be replaced with upgraded incandescent bulbs (or LEDs). But that would not affect the performance of the headlights.

This is just idle curiosity...
My 2021 i20 SE Connect has headlamp-units with halogen bulbs that can be replaced if they fail. The image below shows the underside of the headlamp unit with the yellow circle showing the 'cap' that needs to be unscrewed to access the direction-indicator bulb, and the green circle shows the cap that needs to be unscrewed to reach the main/dip-beam bulb.
The following image shows the underside of an i20N headlamp-unit. This (as I understand it) has no replaceable bulbs and - if any of the unit's LEDs fail - the complete headlamp-unit has to be replaced. If that is correct, does anybody know what the large 'cap' I have arrowed in red is for?

I have the same problem (with the high beam not being high).
My Hyundai dealer tested them to be fine ... I assume the only looked at the low beam because those measure devices are made for low beam adjustment.
Now I found the "hidden" screw to adjust them, but some has to take out the headlight to adjust them. They are protected somewhat and you adjust the offset to the low beam with them.

Now I can see in the dark ! 
OK, you can do it with the headlights in place ... but I wouldn't call it easy.
On one side is the cable in the way and I disconnected the plug to be able to push it out of the way. One important thing, DON'T lose the screw holding that plate ! I let it on there dangling around.
up = clockwise
I turned them 3 rotations up.
There went definitively something wrong in the factory, because mine pointed at the ground about 20m in front of the car.

The position of the cover 'plate' over the 4th screw is shown by the green circle and green arrow in the next two images
For what it's worth, the halogen-bulb headlamp-unit fitted to my i20 SE Connect has a similar cover (that presumably also covers an adjustment screw) although the cover's position on the my car's headlamp-unit is different.

Are these the FULL LEDs or the halogen ones? Thank YouNow I can see in the dark !

OK, I think I now understand how the LED headlamp-units (as fitted to all Hyundai i20N cars) are adjusted.
The headlamp is shown here
and the Handbook describes the adjustment method as follows
Only the aim of the high and low beam LEDs can be adjusted, and this is carried out by turning 'drivers' that have a hexagon head that also includes a screwdriver X-insert. There are four drivers and the head of one of these is partially hidden by a small metal 'cover-plate'. This cover-plate is attached to the headlamp by a Pozidriv screw that will need to be undone to allow the plate to be swivelled sideways so that the driver can be accessed in order to turn it. (The cover-plate plays no part in the adjustment itself - it just gets in the way!)
My own i20 SE Connect's non-LED headlamp-unit has a single H19 twin-filament halogen bulb providing high and low beams. Vertical and horizontal adjustment of the aim of those beams cannot be carried out on an individual basis, and any change made to the aim of the high beam will also alter the aim of the low beam (or vice versa). Consequently, my car's headlamp only needs two 'drivers' - one for vertical adjustment and the other for horizontal adjustment. Although my car's headlamps carry a similar 'cover-plate' to that of the LED headlamp, the plate (apparently) does not obstruct access to the driver next to it. (I've no idea what is under the cover-plate!)

you turned all 3 screws in the picture?Now I can see in the dark !

It would be useful to know the purpose of each of the four adjustment screws.
I have assumed that two of the screws are used to adjust the high beam and two of the screws are used to adjust the low beam, with one of each pair of screws adjusting the vertical aim and the other screw adjusting the horizontal aim. Presumably, if it is wished to just adjust the height of the high beam, only one screw on each headlight needs turning?

I adjusted my dipped beam before Christmas and it made a great deal of difference. This was how low they were. The line is 670mm low beam cut off point as listed in the manual. I could only get the board 6m away on flat ground, but the beam was 70mm lower just at 6m. Using some man maths that gave me that the low beam was focused no more than 50m down the road.
I used a long screw driver to adjust then. but it felt "wrong". I have just been out to have a look and can see why. This is the actual adjuster. You can adjust it with a spanner. If you have one of the lovely ratchet types, your life will be far easier. However, the adjuster has teeth on the edge which a pozidrive screwdriver will engage with. You do need a long screwdriver though and better to use a spanner.

Thanks
Each of my 'common' i20's halogen-bulb headlamps has two two adjusters, unlike the four adjusters of the LED headlamps fitted to more upmarket i20 models and the i20N.
Logically, it must be practicable for the headlamp aim be adjusted with the headlamps in place and, although I think I could rotate the uppermost adjuster with a slim spanner reasonably easily, I'm unsure whether I could do the same with the other less accessible adjuster without first moving the wheel-arch liner as if I were going to replace the main/dip bulb.
I might try experimenting, but not until Spring...

You can most definitely adjust the lights without having to remove the unit from the car. However, I very much suspect the operation is different between the filament bulb head lights and the LED ones. Generally with "normal" filament bulbs, you will make adjustment by moving the whole reflector in the headlight housing to change the aim. With the LED ones, particularly as you can adjust both the main beam and dipped beam independently, within what looks like a single reflecter moulding, you must be moving the the LED bulb position within the unit to change the aim.
The headlamp aim adjustment guidance in the Hyundai handbooks for all current model i20 cars (including the i20N) has a drawing of the rear of the headlamp-unit. However, that drawing is of the non-LED headlamp variant fitted to cheapo i20s (like my SE Connect) where main and dip beams are provided by the same twin-filament H19 halogen bulb. Consequently my car's headlamps have just two adjustment 'drivers and (as you've said) these will move the whole reflector. One driver must alter the horizontal aim and the other must alter the vertical aim. It's tempting to think (hope!) that the more easily reached driver that's nearer to the top of the headlamp will handle the vertical aim, but the only way to prove this would be to rotate that driver and see what happens.
I have now had the opportunity to examine my i20 car's (halogen bulb) headlamps more closely and it's plain how the aim of the beam is adjusted.
This image shows the headlamp's upper surface
There are two holes - one for vertical adjustment and marked for Down or UP (green oval) and the other for horizontal adjustment and marked for Right or Left (blue oval). The end of a suitable tool inserted in a hole will arrive at the appropriate adjuster.
Although a cross-head screwdriver is sometimes recommended be used for the adjustment task, advertised headlamp adjustment tools suggest that the end of the tool should be a male hex or star type, depending on the make of the vehicle. In my car's case, as I would only be interested in vertical adjustment and I can reach the (13mm male) head of that adjuster fairly easily, I'd make myself a bespoke spanner (with a long piece of string on it for when I dropped it into the car's undertray).

I made this adjustment last night, all you need to do is move the metal cover out the way and just turn the adjuster ( top left one in the pic) to adjust just your high beam. Found mine just fires low and just created a puddle of light where the dip beam is. Much better now. NOTE: this will not effect low beam aim at all which are regulated in the UK MOT.Now I can see in the dark !

Just taken delivery of my i20N and first time out at night the high beam was certainly more low beam, quickly resolved by adjusting the setting from 3 to 0 for just two up with no luggage. What a difference!
