if you mean: "why do hazard lights flash when brakes are on", then the answer is because vehicles are equipped with a hazard light relay that supercedes the brake lights. This way, slow moving vehicles can operate under hazard lighting.
To make the hazard lights alternating flash, a kit called a wig wag is added to the flasher system. To have actual strobe lights, then a strobe kit with its own light has to be installed.
what car have you got?
A flasher relay interrupts power to the hazard lights making them flash. The relay can be a dedicated relay or it can be the same relay that operates the turn signals. Depends on the make, model, and year of the vehicle.
If the lights come on but do not flash, replace the flasher relay. If they will not come on check the fuses.
The hazard flasher on a 2001 Toyota Camry is located under the dash, near the hood release. It triggers the hazard lights to flash and regular intervals to notify other drivers.
it may be a loose connection on the back lights give a good firm push on the connectors
If you just barely touch the brake pedal the brake lights will come on but the brakes will for all intent and purpose not be applied.

Answer You might want to check your flasher relay which is under the dash.
You have a bad relay. Your blinkers run on a different relay than you hazards do.
If lights light up but do not flash, then need to change the flasher, if no light at all chk all fuses first.

If this occurs under heavy braking (i.e. ABS has kicked in), then the hazard lights will start flashing. They will turn themselves off after a few seconds of normal driving. If it occurs whilst generally driving along, it could be a bad connection in the hazard light switch, or something more technical inside the car itself.
Start by replacing the Flasher Relay.
Hazard lights, the triangle button. It makes both of your turn signals flash. Other possible ways to notify people that your car is a hazard: Holding the hood on with bungie cord or duck tape, using body kits to look like a ricer, obnoxious mufflers, missing lights, using zip ties to hold parts of it together, etc.
Check to see if the bulb that does not flash is going bad, or is burnt out.
If neither signal light works, the flasher may very likely be the problem. The hazard lights and the signal lights work off different flashers.
I dont have an answer but I am having the same problem. My car wouldn't start but when I turned the key, the lights (hazard and dash lights) started blinking. I think it's a warning that the battery is not completely connected. We tightened the clamps (which were very loose) and it stopped.
There is a short in the wires in the turn signal circuit. The combination switch in the steering column is a good place to check. Do the hazard lights still flash?
What fireflies are looking for when they flash their lights are mates, but there are other reasons as to why they would flash their lights. They flash their lights as a survival method telling their predators that the chemicals in their light has a very bitter taste. They also use their light as a warning to other fireflies to stay away.
