DIY - Changing Car Bulb Lamp to Superbright LED

I've done the first experiment replacing incandescent light bulbs with LED light dot matrix. From the experimental results obtained that apparently turns a rather high heat in the resistor. This is because that too much current flowing in the resistor. Another problem is the brightness of the light produced is less.

o overcome these problems so I tried to replace it with a dot matrix LED Superbright LED. Dot Matrix LED Superbright but hard to find in the market. Therefore I use a set of 3 mm LED Superbright arranged into a collection of 5x7 LEDs.

To turn on the LED,the current required is 25 mA, while the applied voltage source is 12 volts. so the resistor needed is approximately 330 ohms. Schematic drawing can be seen in the figure below

The final step is closing the outer reflector and performed tests on the system by using a 12 volt battery voltage.

Have fun with this experiment.

With creative and innovative tinkering, we will get the satisfaction of creation !
