I just want to start by saying I have some knowledge, being an Industrial designer, but I am by no means an expert.
I have a set of US taillights, that I have successfully converted to UK regulations (yellow indicators) and I am currently working on a dual function tail/brake light feature.
I have built a PWM 555 circuit to lower the brightness of the lights and that works great, however, to get the full 12v to the same lights (to function as brake lights) I am not sure what the best way to go about it is...
In the image attached, the LEDs are hooked up in between the DRL signal and a mosfet. In order to trigger the LEDs full brightness I can ground the negative side of the LEDs, bypassing the mosfet and entire PWM circuit.
But, I would like to use the positive 12v brake light signal already in the car, is there a simple way (another transistor, relay or something similar) to use the 12v signal as a switch to connect the LEDs to ground?
Is there something I'm missing here?
Thanks for any suggestions!
