Since I sorted out all my vacumeleaks and lubricated all the rusty points in the headlights mechanics, my headlights go down very fast.
In fact they go to fast.
http://www.youtube.com/watch?v=zAaebUKMHdAIt is clear that this is not to good for the bulbs.
Especialy when you have more expencive bulbs mounted you don't want them to be killed by this system.
I found a simple solution to make the vacume adjustable.
Go to the car-shop and buy this thing.
Price around €2.-
It is a T splitter for screen watersystem 6 mm.
Make the mid point a bit shorter.
Get a bolt M5 long enough to adjust the vacume to close.
It will work as a adjustable valve.
Cut a piece of this hose and place it there.
Now you can adjust the speed closing the headlights.
Sorry for the dark movie
