xevision, the leaders in the HID market, and others are pulsing the HIDs.
So yes it can be done it seems. The question may be - how does it effect the
long term life of the HID bulbs? LoPresti puts it like this -
> http://speedmods.com/PowerPulse.htm look at the Urban Myths, and you can compare the systems here - http://maxpulsemaxdim.com/comparisons.htm . However, only one system is STC'd and has the warmup delay that seems to be so important. That is the MaxPulse unit. We cannot say if this is important or not. Everyone seems to have a different take on it. But if the HIDs have a 5000 hour life and pulsing them reduces that life by 10% you are going to be in the pilot seat for many, many hours. Your HIDs could very well outlive you. It would seem that being seen is far more important than anything? Safety anyone?
Max pulse is fine for HID if you run only the fastest pulse rate it offers, 60
pulses per minute each channel 120 pulses per minute both channels. and if you
run them steady on for about 20-30 seconds before you switch to pulsing operation.
The Max pulse only has a ~5 second wamup about 20 seconds too short. The
bulb manufacturers (Philips & Osram) only rate the bulbs for 2000 to 3000 hours
of normal use. I believe Lopresti's hours warranty is based on a hobbs meter
not lights on time. XeVision has a patent pending on automatic bulb warm-up
to substantially improve bulb life with HID pulsing operation.

LED still has a long way to go to compete with HID as a landing light. This is
true in terms of total lumens and reach (distance).
