LED transistor relay with adjested delay

[Hak232]

Hi Everyone,

Am new here but I know there is expert people once it came to electronic diagram.

I have an motorcycle LED light (1pin) and I need to do it always on and when trigger turn signal dedcted, I need be blink with turn signal.

I have read that I can do LED intensity with one resistor but the issue faced that I would like to trigger one-off with turn signal (LED will be turn completly on/off with flasher).

The idea I need the LED always on and trigger signal from Turn Signal that will close power from main line and switch to Turn Signal line source after two seconds of no Signal dedcted, will switch back to line one(always on)

Could anyone help please on this?

NP. Am just interested learn electronic but expert

I think something might have been lost in translation.
Don't follow the "always on" but, ... not always on.
.
Maybe you could draw up a table or something (a state machine, if you know what that is) which describes the states that the system can be in;

(1) nothing happening nothing on, if "turn signal detected" then something (blinking?)
(2) <something> ..., if <something> then <something> after delay of ?
(3) if blinking and turn signal off, then timer on
(4) if timer over then goto (1)?
.
How is "turn signal detected"? From what? a swicth? an indicator?
Delay ciruits are relatively easy, but need a few components.
Do you have the ability to put circuits together?
There may be (automotive) modules you can buy to run turn signal lights. Have you searched for something?
