Xenon High beams
Looking at the fuse chart there are one fuse for each high beam. they are 7,5A. and there are one fuse for each low beam, they are 15A.
So the question sounds, are the wires to the high beams smaller than the wires to the low beams? I have xenon low beams equipped from factory. I guess I can just put in 15A fuses if the wires are the same...
high beam. so the resulting and additional load should be low, ie the
added load should only be the relay clicking and opening the cutoff shield.
....right? or am I not thinking clearly while at work ?
But I think it's a better idea to stretch a new wire from the positive terminal and add it to a relay to reduce load when I have to turn the high beams on and off several times in a short period of time.. Then I'll just add a resistor to the high beam wires to bypass the bulb warning..
How much current do the ballast draw when heating the bulb by the way?
www.danielsternlighting.com has a pretty good schematic of the routing.
But will higher voltage make any difference for the xenons? I thought the ballast was limiting the power as it's supposed to run at 9-16Volts... then 16Volts would mean 46W if it was a resistive load, which it ain't, but you see my point.
But I think I'll rewire the headlights and add some resistors. How often does a xenon bulb burn out anyways? For my headlights I really don't need the bulb warning, as I am awake enough to actually see when there is light missing in front of me... I don't understand how people doesn't notice...

Post under hood goes to battery that is why it is not only used for jump starting but also key out the best charging point for a discharged battery.
I don't think I would try to run a hid system off of it.

I would bench test it with an in-line fuse, maybe a 10 amp fuse will carry it. One thing I worry about is that it took 3 seconds to blow the 7.5, HIDs initial load is the highest once the arc is struck the load goes way down.

The nominal power here is 35W + loss =about 40-45W. This means nominal current will be about 3,5A. As long as the bulb is getting heated the ballast will draw more than nominal power, how much I don't know, but I would think its more than a 55W tungsten bulb would draw. There is probably a reason for equipping the low beams with 15A fuses.
This was a hella ballast, it may draw more current than other ballasts as it heats the bulbs faster.
So when driving with much oncoming traffic I turn off the switch and use only the bi-xenon projectors. and when I'm alone I turn on the switch and make the night become day
I'm getting my headlights properly aimed at the dealer today, and then we'll see

This is at least a whole new world compared to the oem headlights. They were crap

The point with that 150A fuse was that ohlord said I shouldn't run the ballasts from the terminal under the hood, but with a 150A fuse in there it should be able to deliver power to a couple of headlights.
here are some pictures from this evening. It's snow, so the light looks a bit better than what you can expect when there's no snow, or when it's raining.
The pictures weren't the best I've seen. I probably got the focus point of the camera somewhat wrong...
The car. Low beams off. Camera flash is on (it was totally dark outside)
Low beam
Projector high beam, same view
Full high beam, same view. Distance in view is almost 300meters. There is a house in the middle of the view (you may not see it), almost 300meters away. I can clearly see the red color and the windows on that house. It doesn't come forward on the picture though
Full high beam, distance in view is well over 300meters. not able to measure accurately, but from the looks compared to measured distances I would say about 350.

4matic? nooo, its a 220tdta+

(the diesels never came with 4matic for some weird reason)
