Thread: D4 high-beam alignment

No, still possum lights.

If I am interpreting this correctly my 2012 has possum lights.
When I flick on high beam the is a spread of light from left to right fairly high up.....above where it should be on the road.

Brett,
Would you still consider the light output and quality for low and high beam to be satisfactory? Maybe in comparison to other vehicles you have owned! I wouldn't mind the fact that tree tops are lit up a little, in fact i have setup spot/flood lights on a cruiser before to achieve a little of that effect. If the area of view on the road is inferior with vehicles that have this trait, it is definately something i will need to look out for when the time comes to purchase. Don't really feel like modding the headlights on a 110K vehicle. Shouldn't have too!

I am certainly lining up my questions!

Can you ask them - why did they get Stevie Wonder to design the halogen high beam in the D4 with bi-xenons? The D3 had brilliant lights - and this is a major step backwards on an otherwise good package.

Brett,
Wnen the headlights are shone onto a wall, do the halogens produce a wide narrow beam with its lower edge well above the bi-xenon lit area? If so, then your vehicle is also blessed with possum lights.

Hi Mungus,

Thought l might have my 2 cents worth. I have an MY11 HSE with the possum light feature. Even with this 'extra' feature l found the high beam comparable to other vehicles with spread of light at ground level (others may differ with this view). The light directed to the tree tops is certainly brighter and should be spread at ground level instead. I have cured my problem by installing LED driving lights. But as you say, for 100K+ the engineers should have done better.

Regards Trif.

I shall test tonight against the garage wall.
Noticed it a lot when I first picked it up, but now I have an led light bar....and the lighting is bloody fantastic.

When I got my D4 I had two black squares in the middle of the road on high beam. I thought tHis had something to do with the possum issue discussed here. It drove me mad for two months. Turned out to be a problem with the high beam deflector in the lights? After this was fixed my lights are brilliant.
