For your information, you'll need to add a resistor to lower the current or you'll be burning up the leds very soon. How many ohms will depends on how many leds you want to use. For signal lights you can't install it like the pictures because it just wouldn't work or light up the leds. You'll need capacitors and abit of wiring knowledge to make it work. To much to explain in details on the tech as why it won't work. Mainly because of how the current flow on and off (making the bulb blinking). Just remember that LEDs works differently from light bulbs.
