Thread: Replacement high-beam globes for bi-xenon

Yeah mate. Dump some HIDs in your high beam will make a hell of a difference.


I don't know about later model Discos but the Skoda has a CANBUS system. It know if a bulb is blown. Just make sure your don't have any issue with the HID s using less current.


Happy Days

There is no way super bright halogens will be anywhere near as bright as HID.

Sorry but your comments show you do not know much about the lights in the D3/RRS. The Halogen lights in these vehicles and the BiXenons are the same with the exception of the globes and shutter. Putting HIDs in the low beam projector of the halogen housing is the same as having the Bixenons on in low beam - no difference. I do not blind oncoming drivers - the light pattern is no different. People who blind oncoming cars with HIDs were previously blinding people with their halogens.

I get blinded more by illegal hi wattage halogens than I do hids - there are exceptions though.

the focii of halogen and HID bulbs is different, so if you put HID bulbs in halogen reflectors or projectors, you will get a different spread of light. Most conversions do not work very well.

Yes your dead right. I have very little knowledge about D3/RRS lights but I'm willing to be schooled.

What I read from your statement: The factory Bi-xenons include bulb and shutter. You have bulb but no shutter. Same housing.

The shutter is what creates the cut off for low beam so with out the shutter you basicly have high beam all the time. Correct me if I am wrong.

Secondly it's not the reflector thats the problem. It's the bulb position. HID bulbs are much longer than Halogen bulbs. The light hitting the reflector gets reflected all wrong for low beam.

Happy Days.

After testing the lights tonight, it would appear that the HIDs stay low, whereas the halogens are aimed higher. Not sure if these are possum spotters, but the halogens high beam starts where the HID end.

And not sure these being adaptive are the same as normal HIDs.

Must find myself some long dark road to test where the halogens are aimed at, and whether they would be of any use being brighter.

I am so confident that if you buy yourself a set of HID balllist and bulbs for around the $50 mark and your not massively impressed with the light they produce, I'll buy them of you for what ever you paid for them.

I'll need a set soon anyway, when I put a couple of Hella Ralley 4000 on the front of the Disco II. I can buy standard Hella 4000 for about $180ea. I cant get a Hella 4000HID for under $800. So it's pretty worth while converting them.

Just putting my money where my mouth is.

Happy Days.

Face a high wall then reverse away to watch the "fill-in" beams get higher and higher above the bi-xenon beam. Unless you do something about the alignment by tilting the HID globes or the bi-xenon assembly, more light won't do much. HIDs with their greater depth of beam will give a little more light on the road but the flashing bright light on the possums' branches directly above is very distracting.

I have been reading with interest!

Graeme is right the 'Fill In' beams are signalling to some extra terrestrials up in the sky.
I personally could not be bothered mucking around and purchased a couple of good HID driving lights and 'Bob's Your Uncle' I suddenly have light on the road where it is needed. It obvioulsy does not address the sky-lights but that no longer matters. In fact they actually become useful when your are travelling on roads that are tree lined as Sky-lights allow you to pick your way aorund curves when the are just over the brow of a hill!
I guess that some use from them is better than nothing.
