My aftermarket HIDs pulse on start just like the OEM Bi-Xenons so in some halogen vehicles the CCF may be enabled already.

Tor - on the original Bi-Xenons, the globe is on all the time as was mentioned and when you switch between hi/low a shutter moves to change the beam. What is the separate Hi beam on the halogen cars is also a Halogen filler beam on the OEM Bi-Xenons.

If you could get a H7 to H4 adapter you could put in aftermarket H4 dual beam HID globes (have a built in shutter) in the Halogen housings and have Bi-Xenon lights just like the OEM fitout.

I don't know why H7 globes are not made the same as the dual function H4 HIDs but it would be great if we could find some.

The BCU switches power under programming control for low and high beam. Low beam could easily be pulsed by the BCU programming for a few milliseconds when it finds that bi-xenons are specified in the CCF. Maybe I should build a little module to initially pulse the power for my HID fill-in lights so they light-up quickly too.

Either that or the ballast circuitry is smarter than some and pulses on startup. A test would be to supply power directly from the battery to see if they start-up quickly or not.

Some one with a CRO could find out exactly what is happening on a HSE. Didn't you say you have a CRO or have used a CRO on your vehicle ?

I have a little hand-held oscilloscope which I could try to see what's happening for the expected very short duration. A son has just got a decent one with lots of memory for recording so that it can then play back in slow motion.

Edit: It might be a little difficult to switch the lights on and see the oscilloscope at a headlight at the same time.

Maybe - when I had the HIDs in hi beam I could still flash with them because the initial pulse was quite bright and you could do it a couple of times.

The self levelling is very important; we don't want to spill our latte, do we?

What, you and Kev are sharing one?
