puddle lighting?

Hi everyone my first post obviously been following this forum for a while and need a little help with a circuit project design. i have 4 puddle lamps underneath my car that i want to come on with my interior light at unlock but when you open a door they all turn of expect for the doors that are open and when you get in and shut the door they don't all come back on even know the interior light has a delay and fade but if no doors are opened they all just fade out with the interior light does.(there all still powered from that circuit). i have -ve door switches i have thought about just four relays to individually switch the lights and maybe a latching relay from the dome light which gets unlatched when a door is open but if no door is opened then it would stay latched infinatley until a door is opened to counter act that i thought of a time delay relay in series to unlatch it in the event no door is opened. hope someone can help.

Car is 2010 ford ranger australian version

use your domelight wire as your input to a relay that turns on all your puddle lamps as long as domelight is on they will be on.

Yeah I thought of that but it won't fade out I noone opens a door and how will I incorporate the other features I want

So you want each switch individually controlling each light. Then each light to fade out independently? If so, I'm still looking for an old fader based on a 2N3055 transistor.... Not sure if that may require diode to be inserted, but I expect not.

I only want them to fade out if no door I opened since for that portion of the circuit it will be getting power directly from dome light but if a door is opened that circuit is disconnected and an individual relay supplys power to each light depending on which door is opened they only time the lights get power from dome is if I unlock and not go near car.

Each door triggering its own puddle is easy enough - a diode between each switch and the dome. And "unlock" to trigger each dome also easy - a diode from the unlock to each puddle. (I'm assuming the unlock is earthing ie, -ve; what they call ground hereon.)       But if the puddles are dimming with the dome, they won't come back on until the dome "undims" - ie, they need a different hot supply (+12V). If so, if powered from their own +12V, all but the puddle dimming is okay. IE - they all stay on whilst unlock is active, else whenever their door is open. And they turn off immediately their switch (or the unlock) opens (deactivates). Considerations include how long the unlock stays active? (IE - grounded.) Until a door closes? And whether the dome stays on after unlocking but no door opened - or does the car auto relock after a delay (hence turning off the dome?)

this is the relay schematic that will switch the puddle lights on independently from door switches (D1) comes from dome light schematic which ill upload soon

I think your starting to understand my confusing mess I have done some further investigating and I am going to use the unlock signal from keyless entry as it grounds momentarily for unlock I was going to use indicator flash but that gives me problems when driving. The car has a very basic system single-ve pile unlock +ve lock I'd doesn't have any dome features STD just door open light on closed light off I have added a kit which does the dome delay and fade and rapid fade if ignition is on. I use the -ve pulse from the unlock to trigger the delay circuit obviously like opening a for for a split second. From the diagram you can see I have the individual switching figured out just forgot the diodes to isolate each switch. I have made a circuit that uses 5 relays to connect all four lights to dome circuit at unlock and resets after 30 secs hence no door opened after unlock and also resets if any door is opened wich then uses individual relays to independantly turn on light untill another unlock pulse is recieved they are powered from a constant 12v source. My real question is can you help me with a circuit that doesn't use all relays it so bulky ad no it doesn't auto lock after time very basic for brand new car. Thnks dory for long post
