Discussion for Improvement:

Now if you found that you are into fooling around with electronics, here some more equipment you should get:

1)PCB: Make your work look more professional and life much easier and finish the project much faster

2)Multi Meter: You will use it in too many occasions

3)LED Tester: If you do a large amount of LEDs and/or need to change designs frequently-you need it

4)Connectors for the adapters: Make all your end products plug and play

5)Switches (2 way rocker is a good choice): You can turn the white light on and RED light off simultaneously and vice versa. So, in the day, white is on and red is off while at night, red is on white is off.

6)Resistors: You will find a bunch of different resistors will become handy. Couple pots will make optimal design easier. You may also want to add a pot to dim the light in actual use. In this example, you may improve the performance of the light by removing 1 LED and adding a proper resistor to it so that it runs at the optimal of this particular LED. To determine the proper value of the resistor, you MUST have the spec from the manufacturer. LED resistor calculator can be found in the web too easily. Also connecting a 1 ohm resistor
in series is always helpful in design and debug phase.
7)Glue: It's also good to use fast setting glue than the slow setting one like ZAP or IC Glue gel commonly use for your frags. Also make you realize that silicone is not real consider a glue but more as a sealant. Finally. the heat glue I was using in this example is not to be used inadvertently, because since it heat melting, it set to melt in low level of heat which render it not suitable higher power design. If you ever plans to enclose the LED in a water proof box, replace it with other glue.

Note: If you have some old but working cell phone charger, post a CLEAR pic of the label in your reply so that I can tell you what it means. I am going to write another example of using an old cell phone charger that is not 12V. You will need to know more about electronics than the "almost fool-proof" version above.

ENJOY and hope you find this article useful.
