Flashing Light

How would I get a light (in this case, a vehicle’s running light) to flash on and off at regular intervals?

Are you using Unity point lights or textures? For point lights of that sort, you can easily use component code. MyCar.GetComponent(Light).enabled = false; and to get it to turn on an off at regular intervals, just have a while-loop go until a certain condition is met (like turning a boolean on and off), using yield WaitForSeconds(X.X); (X.X is any time you want) within that while loop. I use it in my Invincible Mode function. (Same principle, but you’re just turning a light on and off)
