The basic idea goes something like low beam=high send 2 pins high then if the lowbeam input goes low for a short period of time (maybe a second at the most) but the highbeam input goes high it sends all 4 pins high if no input is seen after that short delay all the pins go low
f you meet someone you have no headlights for a good 10 seconds.
I find this description confusing. Could you write it out with each step on a separate line.I suspect if you describe what you want clearly you will also understand how to implement it.Why isn't there an instantaneous switch-over from High to Low and Low to HighHow do you control the lights while you are driving?Can you have High and Low on at the same time, or does that require too much electricity?...R
Perhaps if you had read the description as to the type of headlight you would know why they take 10 seconds to come up to full power. The're hid's and they dont just come on instantatly they must warm up.
Describing a headlight as a HID means nothing to me and I don't see why I should be expected to do research when a simple explanation of the acronym and how they work would have made things clearer. Your description of the problem did not make the problem clear as far as I am concerned and I suspect that others will be in the same position. Your requirements for pins to go HIGH and LOW did not help me either because it is not clear what HIGH/LOW do in the circumstances. Can you please describe what should happen in terms of the lights ? At the moment it seems as though you simply want the low beams to stay on for 10 seconds when the switch controlling the headlights is changed from low beam to high beam. Is that what you want, assuming of course, that you cannot simple have the low beam lights on at the same time as the high beams.
