Calling all Xenon / HID experts!

[pudding]

Lol, nice attempt to bore me (and others) but you failed miserably because I found it quite interesting 

Do you happen to know what might cause xenon bulbs to wobble over bumps?  2 x MK5s and 1 x MK4 and they've all done it.  I can't be that unlucky to have 3 sets of dud lights?!     The projectors are all in there solidly.  Can't feel anything loose in there.

[Ripstop]

The short answer is no.... however I have always had my doubts about the mounting mechanisms for the starter and holders of D2S xenon bulbs. The actual projectors and lenses are locked pretty solid and there are no moving parts as such in the bulb but there is a fair amount of weight (relatively) in the bulb and starters so it acts like a seesaw around the fulcrum point where it held in the light housing. Other than that I think its fairies at the bottom of the engine bay 

My suspicion is that it is a "wobble" introduced under certain conditions ie bumps. I also get a very minor wobble sometimes too.

Rip.

That is certainly a plausible reason!  It's a heck of a lot of tech and bulk for a couple of bulbs isn't it!

When I had my squidgy 16" winter tyres on last year, the wobble practically disappeared, so it must be a trade-off of stiff suspension and/or 18" tyres!

Cheers for the info Ripstop. I think there's definitely room for improvement with the current setup then. A pair of 4300k bulbs and check the alignment and I'll see how that goes!

Just thought I'd add a little update after spending a bit more time with the Depo and HID setup.

I think my initial disappointment was down to the fact it was more dusk than dark - maybe the colour temperature of the bulbs makes the beam a little less obvious in those conditions.

Since then I've done a fair bit of night driving, and actually, they're pretty damn good. There's still scope for a slightly whiter bulb, but the current ones don't seem too OTT blue. I managed to find a wall in a carpark to test the beam pattern and it seems good. Nice cutoff and height - although I'd like to get that confirmed at my MOT place. I haven't had any oncoming cars flash me or anything, so I'll loosely assume things are as they should be.

Overall, I'm happy with the upgrade.

For absolutely anything lighting related I'd get in contact with Trups at EM Tuning - he is an absolute lighting guru.

He can split headlights and reseal, change projector lenses, fit colour changing demon eyes, paint headlight internals etc etc. He's developed his own LED products too.

Here's the output from my RS4 xenons after he upgraded the projector lenses to crystal clear ones he sources, and bulbs to morimoto ones:

Like the look of that. Cheers for the info mate

Hi AJP

HID are s**** mate

Check my build thread on the latest bulbs I'm using and 100 times better than these poxy hid kits

I've heard of places that retrofit new projectors into headlights to get improved visibility etc can't remember the exact one i saw a recommendation for i think it could have been;

I saw a bit of that, mate. LEDs aren't they? Nice to have better options down the line :)

Cheers mate. Along with the recommendation from FJ1000 that gives me plenty to go on

yeah mate led's and I found them much brighter and definitely light the way home  cheaper than the clear projector option unless you're ready to get the lights out and mess about with them.

I have also just fitted a set of depo projectors last week along with a hid kit and 6000k bulbs. Mine seem to be throwing light everywhere which is what I was hoping the projectors would prevent!
I measured the two adjustment screws on my original halogens and set the depos to the same measurements. But one side is now lower than the other and as said beam pattern is abit all over the shop. I plan to try fiddling with the adjustments again to level them up atleast but a pain as have drop the bumper again 
They are definitely brighter and better than when I had the gods in the standard halogen lamps but I definitely need improve the setup abit as don't want blind everyone or get pulled over for it!

Do the 6 O'clock mod and that should sort the beam pattern out. I've gone for led bulbs and far more superior than the hid kits. My motorway experience going to Birmingham with blinding as with on the way home it really does do the projectors justice
