Hi
New to the forum and hoping to get some help. I have a car accessory with LED lighting on that is too dim for my liking. I have attached photos of what I suspect is some kind of voltage regulator or dropper. The input voltage is 12v and the output is 7v. I would like to somehow find one or modify this one to produce 12v output, hopefully making the LED brighter but keeping the voltage regulated so as not to damage the LED. Can anybody please confirm what it is and where I can get one
Many thanks in advance

 

If you need a 12 V regulator, you can put a 12 V zener diode across the load.
But before you do that, you need a resistor between the 12 V source and the load in order to limit the current to the load otherwise you would risk burning out both the zener diode and the load.

You need to tell us what is this accessory or provide a link to it.
