Thread: High Beam partially stuck on

....the issue but it was stuck all the way home

The bixenons have a mechanical shield for hi/lo . Only one light element
unlike halogen bulb headlights. When the Bixenon is on , does the inner halogen
function. Mine only uses halogen for flashing the lights IF THE bixenons
are not on ( bixenons have a slow response time .... )
The "elements" move , you think ............ umm
Can you get both types on together ?

That's what the service guy said but maybe he was referring to the shield. What I need to do is look for myself. I'll set it up tonight and try and work out what is or is not happening and get a better description.

Basically when you go back to low beam the lights still reach into the distance and high on the sides but the intermediate reach drops back again. Sorry hard to describe. But it doesn't work like it used to!

This could be a software glitch .......

Ctrl-Alt+Del and kill the process!

Inner lamps go on and off with the high beam. What should I actually be seeing in the bixenons (without going blind). I guess what I am asking is there a visible reaction in these lamps close up.

Thanks for your help by the way. I didn't realise how these worked.

Ctrl-Alt+Del and kill the process!

I was going to try that but my Mac doesn't have an ALT key.

The bixenon tube is an on or off device. The mechanical blind
blocks the top part of the beam on dipped , and allows all
the beam on high . I love 'em . They beat the Hell out of Halogens.
With the light off, you can see the blind through the lens .........

I believe the halogens are only installed to meet ADR for a "light flash"
device , which is strange since what about "flip-up lights" ?

Its illegal to flash where I live, so I can't see that its an ADR requirement.
The halogens are required by ADR to fill-in the sides of the bi-xenons as the bi-xenons don't illuminate sufficient width. You will see that the halogens are a wide strip, on the D4 anyway, although some like mine illuminate possums in the branches above instead of the road.

Well after some research and the helpful input here I'm thinking that the solenoid that changes the shutter/blind position is not actuating and it is now stuck in the high beam position. The halogen infill lights work fine.

I'll have a very close look at things tomorrow.

cheers
