Stupidcar, just a suggestion for your DIY. Put a zener diode before the resistor. This helps regulate the voltage going into the resistor and the LED. Previously I didn't think of putting diode and use resistor as a form of voltage regulating but it was not very good as the voltage in car will vary from 12V to 14.5V. Also resistor's resistance sometimes might not be like what they stated. It's more safe to put a diode.
Nvm lah, cheap mod.
From LEDs resistor calculator,
i put 2.8v forward current which is the minimum, maximum can go 3.2. Reverse is 5V.
I didn't use just one resistor for the whole setup, hopefully it will be okay.
Normal lights i put 5 LEDs for a 100ohm.
For brake light 4 LEDs, I put 100ohm because it doesn't stay on for so long so it can tahan.
I get it lah to maintain it's reliability. Thank you
But then my friend did it using this set up for dome light, it's been a few months.
The LED's all same wattage, how do you light them dimmer for lights and brighter for brakes. Only using the resistors?
Different set for brakes different set for tails function ma.
No need dimmer function, I tested it with multimeter from the brake lights plug.

VR2, no he's not making them dimmer. All the LED will be having the same brightness he only configure which row to light up on power and which to light up on when brake apply.
Example you have 4 rows of LED
4 rows you tap the power from the tail lights but 2 will tap from the source when you turn on lights the tail lights will be on. Another 2 tap from the source where there's only power when you apply the brakes.
IF use driver then only can achieve the dimmer and brighter effect as driver got 2 output.
Yeah, I get it. But i'm just experimenting.
I will only do this IF my taillights kaput.
This is just decorative.
