Thread: D4 high-beam alignment

i have nothing to back this up, but i think the "shaking" of the xenon lights on the D4 is normal - the light source as i understand is an arc of "electricity" between two points through gas, and this can move about a little bit.

happy to be proven wrong...

That is a reasonable excuse - but it never happened in the D3.

No shaking on my D3 and Rob has had both and noticed the difference.

I had forgotten that my D4's lights shook, but the shaking seemed to stop about the time I fitted D3 shocks.

An interesting theory, but I don't think so.

I had HID conversion High beams and HID Lightforce driving lights on my previous car a Grand Cherokee and they never shook.

Considering the driving lamps were spot beams and shone for several killometres. It would be fairly obvious if they did.

The odd harsh bump in my Subaru Liberty used to cause the HID's to give one "flicker". Never a big deal to me.

I live in the country and try not to drive at night as I do not have a Bull Bar fitted yet. Got caught at work last week and ended up driving the 60km to home after dark. That gave me the opportunity to check out the D4 high beam issue for myself. Just like many others my high beam lights were a surprise when I first turned them on. Great for checking out potential 'drop bears'.

As I got used to the light pattern it seems as though there is a spread of light across the road ahead but certainly not concentrated where you would expect (require) it to be. Seems as the central part of the high beam is set straight ahead (in the trees) rather than to the road at some distance to the front. After reading through all the posts in this thread I have come to the conclusion that I will have to live with the issue and fitting a good set of driving lights to infill the obvious mid road gap is the go. At least its something I can do and get a reasonable result.

I have contacted the selling dealer and they want to discuss the issue with me when I am next in the big smoke. They have sent me an e-mail stating that the lights when on high beam are 'different'! This will no doubt be an interesting discussion. I have not noticed any "shake" from my lights but will look more closely when I next have to make the trek at night.

I had a D3 SE and thought the bi-xenon lights were fantastic. So much so I paid for them as an option on the D4. Seem as good to me on the D4 as they were on the D3; no shaking noticed to date.
