Hi,
I might need to create a circuit that detects when both the signal lights are on (hazard lights) and then activates the center light on my bike.
Means the center light should be off when only one side is lit.

I there a ready module I can buy, plug and play for this project, or I realy have to make an AND gate.

Aside from AND gate, anything else I can do that produce the same result?

 

Lighting the center light is not a standard hazard flasher function.

 

What exactly is a "center light"? Signal lights as in turn signals? I have no idea what you are asking.

two transistors and two resistors to form an AND gate. you could also use MOSFETs

 

What function lights the center light in the present arrangement???Is it red or amber or white??

 

If the lamp is already lit by another circuit, such as from brakes, then the AND gate in post #4 may need to be a high side version.

 

I already have Dualcontact LEDs on my signal lights. which I'm also planning put one in the center that only activate when both of the signal light are On (Hazzard Light)

 

If the lamp is already lit by another circuit, such as from brakes, then the AND gate in post #4 may need to be a high side version.

sorry forgot to mention that I'll be using a dual/double contact LEDs

its white, and amber when other positive line is connected, its double contact bulb

parklight (centerlight) because theres only one at the center.

Yes, signal lights (turn signals)

 

high side version...
Q1 and Q2 can be small, as in this case only Q3 handles the load current...

 

If you want a "plug and play" arrangement to accomplish the same function, use the standard cube style automotive relays, each with the normally open contacts in series to light the center light directly from the supply.

thank you, I'll this to my option

thanks, I'll go with this setup
