Hey there.
This is my first time messing around with LEDs, but saw an article by Bareass choppers and they made it seem very straight forward. So, I switched things up off the jump and went ahead and bit off more than I can chew haha.
I need help calculating what resistor I need on the tail light power. All the calculators online are for single bulbs, I have built two arrays of four leds and need them to function with dim (running) and bright (brake) functions. Most of the info I needed was taken right from what was in the Bareass article. However, with fewer leds in my cluster than theirs does the resistor on the running light power need to be changed to make up for the difference or am i over thinking things?
Im thinking that it might still work but wont dim them to the same extent that it would have with 12 leds making the difference between my running and brake lights less noticeable. I just want to make sure its obvious enough for the space cadets out there, they scare me enough as is. A blonde air head stopped opposite me at an intersection waved back when I made a right yesterday…
Ill include a link to the original article and a crude little diagram of what I have so far pointing out which resistor it is I am unsure of. 12v system by the way.
Side question, how are all the nice diagrams i see on here created? Mine is embarrassing and Id like to do a better job next time haha.
Heres the original article
