power LED strips via car battery? Answered

I've got a little project where I'm installing RGB LED strip lights in and around my car. They are 5 volts strips and looks like it'll require up to 10 to 12 amps for the total installation. Can I use the car battery to power this? If so, how do I go about doing this?


yes. you will need a really big power regulater or a bunch of small ones.

looks like you're right. I can't get a big regulator here in time for my project, but I can get a bunch of small ones. Do I connect all 6 small regulators directly to the car battery? I imagine that's bad practice

no i would split up the strands of lights and divide it between the regulators if you dont know how to do it just tell me

for 5 volt LED strips off of a 12 volt battery i am confused? but maybe all 7th graders are confused?

Here's the diode method.


run them in series pairs, on 12volts, and put two forward biased diodes in series with each pair.
