    Ok, i have a bunch of things that i would like to build and not buy because my father wouldn't like me to just buy them and he would rather have to build them and he will buy all the components i need. If you guys could help me i would mainly like to know what kind of LEDs are used in these because im not really good at figuring out how many LEDs can be supported by a 12v car battery. I would like the number of LEDs that it says are in each product with the high brightnes. And if you could give me a website to buy these LEDs it would be greatly appreciated. I know some of them are like five dollors if you just buy them, but i want to experience making these items.

    Now i know that these are police lights and i do not have intent to put them in my vehicle. I would just like them for display still using a 12v car battery. It says that they use Linear Super-LEDs. Only thing i would like them to do is flash back and fourth in this pattern: Left Left Left Right Right Right in about 1 to 2 seconds. I'll buy the pic board or whatever i need.

    Once again this is a police light. It says it uses 368 high-intensity LEDs in each mini bar which there is two mini bars. I would like to have it do the same pattern as above: Left Left Left Right Right Right in the 1 to 2 seconds.

    Any help would be greatly appreciated.

    To buy superbright is not the problem. goldmine has 45000 mc. there are of course power LEDS that can blind you. they are not exactly led but small as leds the current consumption is not 20-30 ma but ruther 5-7amps. Since the size is small 5mm it is important to dissipate the heat from the device. I will suggest that you try leds first before buyng theses devices.
