LED 3rd brake (Built not bought)
What happens when your bored with 500+ 15000mcd LED's, A few hundred sorted resisters, and a spare 3rd brake light setup?
So the setup was as followed.....
three rows of 3 of 3 LED's, all are going to be set up in series then in parallel.
this means that if one LED happens to go bad, the rest will still be working, while all of them will be supplied by the same power source.
What LED's and Resisters did I use?
24 red 15000mcd 5mm LED's
with the correct math you can get the right resistor size for any combo.
Current combo was one resistor per LED.
Here is the math.....
R = (12.0V - 2.3V) / .02 A
R= 485 Ohms
This we need to round off to the closest 5% value.
so I used a 560ohm resistor since its a popular and its a easy to get resistor,
and it will also insure a long life for the LED it will be attached to.
Here is one side finished
Here it is completely finished and wired up for plug and play.
Here is a closer look at all 24 LED's, 9 on each side and 6 where the 914 light bulb once was. The 6 LED setup is also a series parallel setup.
this one I was suppose to use a 390ohm resistor, but I just used the same 560ohm to bring the brightness of the lights down since I would have 2 LED's per 1 resister.
And now the finished product.
