Hey everyone,

Just wondering if anyone is aware of a method of adjusting the high beams only on a 2IS. I replaced the high beam halogen bulbs with LEDs some time ago and while they do light up nicely, they seem to be pointing quite low in front of the car, as opposed to pointing high up and lighting up long roads when driving at night. Output is still great since they are about 10,000 lumens each which is miles better than the stock halogen bulbs.

Weird thing is that low beams are fine. The only thing I can think of is the difference between the two bulbs, since a regular halogen bulb will light up in a 360 degree radius, while the LEDs that I have fitted have two opposing diodes.

Google did not yield any results on adjusting high beams only and I don't even know if that's possible. Would appreciate any tips if anyone is aware of how to adjust high beam only.

I Think you might have problems come MOT time when headlights are checked! ( if you have to get MOT that is!) 

Either way after market LED bulbs ( Lamps actually…..”Bulbs Grow & Lamps Glow” an old Electrician told my, more than once, when I was an apprentice sparks) do not normally give out a beam pattern that is workable with the lens and diffusers that are in the car as OEM and have been designed for halogen lamps. Newer cars that have LED headlights are designed for them. I would therefore not want to be driving in front of you at night for very long!

I'm not from the UK so no MOT issues here. Blinding is not an issue as well since high beams are off when cars are in front anyway. I tend to travel at night and good bulbs that can light up long roads make everything easier.

Still, will try to rotate the bulbs and see if there is any improvement. Will update if I manage to make this work.

Why not just get upgrade halogen bulbs? 

I agree.

I’m guessing that it’s an HB3 fitting for your models Main  beam, but I fitted the Osram Night Breaker Laser in my 2015 IS250 and have been delighted with the results.

it was like switching from a Toc H standard of lighting - and yet in fact the originals actually were halogens!

Worth a look, I suggest.

Normally the adjustment screws accessible from the top of the headlights is only the horizintal adjustment.

For the height adjustment you need to remove the plastic wheel well liner.

If you have separate low and high beams, there are sepatate adjustments for each beam for horizontal and vertical.

For maximum visibility without blinding oncoming traffic, dip the low beam to 0.2 % from the horizontal reference mark on the low beam.

I did previously test out upgraded halogen bulbs, however, there was barely any improvement in brightness.

As for the adjustment screws, there are only two of them available that move the entire headlight assembly vertically or horizontally. This is what prompted my initial question, in case there is a not-so-obvious way.

Yes that is all there is. The headlight is a complete unit so if one beam is set correct the other one is too (if the correct bulbs are installed).


Since the low-beam light and the high-beam light are a unit, if the aim on one is correct, the other should also be correct.

Check the bulbs are the correct ones and from quality brand, they are seated correct and your low beam is in fact properly adjusted. My above quote is from the official repair manual - there is no separate adjustment for high and low beams, just for the whole light assembly.

I'm going to attempt rotating the LED bulbs in a different direction to see if this will help with the aim, even though I'm pretty sure they are currently set properly. Will also stick in the original halogen bulbs to see the results.

I would have fitted an HID kit by now, however, the HID warmup period means that they aren't really viable when you have to constantly turn them on and off.

I'll make sure to post an update when I've had the chance to do this.

    • 10 years of Lexus design: from spindle grille to spindle body
      After 10 years as a defining style feature of every new Lexus model, the famous spindle grille is undergoing a transformation. In tune with a new era of electrified vehicles, the distinctive shape is evolving into a new “spindle body,” as seen on the upcoming new generation Lexus RX SUV and the all-electric RZ.

      The spindle grille has been an unmistakeable Lexus feature since it was first revealed on the LF-Gh concept model of 2011, the basis for the fourth generation GS executive saloon that was launched the following year. Since then, it has been constantly adapted to suit the character of each successive Lexus model, with different mesh patterns, dimensions and finishes.

      Speaking at the time of the grille’s debut, the then Head of Lexus Kiyotake Ise said: “You should be able to identify a car as a Lexus immediately… Instant visual recognition, for example, is the reason behind our spindle grille. It may look aggressive at first glance, that’s intentional, but it also conveys its boldness with sophistication and elegance.”

      It has progressed to become a hallmark expression of Lexus’s L-finesse design, adopted not only for road-going cars, but also incorporated in the futuristic Skyjet spacecraft created for the Lexus-supported movie Valerian and the City of a Thousand Planets and adopted as a design motif in the Loft, the award-winning Lexus and Brussels Airlines lounge at Brussels Airport.

      Today, the original grille concept is the starting point for a more radical application of the spindle shape in which it becomes an integral part of the vehicle’s overall design. This “spindle body” approach is part of the Lexus Next Chapter design for the all-new RX, where the grille is reinterpreted as a seamless unit that flows into the bodywork. The lower section retains a mesh pattern, while the upper section takes in the lower edge of the bonnet; the Lexus emblems sits at the centre of the spindle’s high pinch-point.

      The same concept has been applied to the RZ 450e. As a battery electric vehicle, this requires less cooling than a car with a conventional engine, so the grille has been dispensed with, giving the designers greater freedom. Nonetheless, the spindle shape remains prominent in a central front panel, finished in the car’s body colour. Its impact is heightened by the adjacent frontal areas being contrast-finished in black, the low bonnet line and more boldly shaped front wings.

      On both models, the spindle generates lines that flow back from the front of the car through the bonnet and headlamp units to create a strong and distinctive frontal appearance, reinforcing the brand-defining ambitions of the original concept.
