I am looking to create a hazard strobe light effect, similar to that on construction vehicles, by using the cars existing reverse and turn signal lights.
I would to do this using Arduino. I am not sure if this is possible, but I would like to connect to the lights from the front of the car, in the same fashion a remote starter is connected, by connecting to the multi colored wires using a wiring diagram.
Is this possible, or will I need to connect directly to the light bulbs connectors? Also is it possible to do this without interfering with the cars ecu? What if the cars brake or reverse light are on, and then I turn on the strobe controller, will I mess anything up electrically?
Also, would there be a major difference between LED bulbs HIDs and halogens?
I know this is somewhat possible, as there is a product that does something like this, albeit it connects via OBD. It's called Speed Turtle. Connecting via OBD would be better for me, but it is probably much harder to code.
Any ideas on where I should start?
