LOLLLLLLLLL macam simply open thread ma. Not good for my rep.
Rep on the internet is worth nothing. Just share. If its helpful, you will build trust.

You don't worry so much. If you're overstepping I will be the one to kick your ass so no worries dude. LOL
Bahahahhaa, then bad rep dy.

Let me help you a bit here la since I've done my own DIY LED 3rd brake light
No.1 you need to find out below
Vs = 12V DC
LED Fv
Normal red ones are 1.9 to 2.1V
High Output about 3 to 4V
mA you intend to supply to the LED 15mA or 20mA higher the brighter but I will put 20mA the max to preserve the life span of the LED
How many LED you want to put in the strip.
Only then you calculate the resistor you need to use. If say you calculated the Ohm to be around 566 or 745 Ohm get the higher than the ones you calculated. 566 you get 600 Ohm 745 you get close to 800Ohm. Also do look into the Watts of the resistor 2Watts is enough for me
My suggestion is that you do all the drawings and calculating on papers 1st before moving to actual project. This is how I do it. You also need to take into consideration the wiring of the multiple LEDs. If wiring multiple LED best to use parallel because if 1 burn others will still light up. If use Series, 1 burn the whole line of LEDs will not light up.
In the below pictures, you will see I'm using parallel series for the entire circuits and I use minis series circuit for each group so if shit happens only 1 group of the LEDs won't light up the rest will still continue to light up.
If I wire all in series, it will draw more current from the source and heats up the wiring because of more current flows. Parallel on the other hand will make all the LED take the same voltage after the resistor and current is spread evenly across all LEDs. This also depends on the individual LED tolerance to voltage variance.
For Knight Rider, not that complicated if you know how to do it. Just go get a running light module and hook it up.
My previous DIY
1st draw out a plan of attack and calculate
2nd fabrication phase
3rd testing and assembling

I saw urs man. But 3rd brake lights are still okay.
How about the normal brake lights?
When brakes are applied it become brighter. and so on.
When I got my stuffs dy, gonna experiment then.

The normal 2 brake lights. As in the tail lights.

Dont know how much to offer you...
Better you quote me the price...
My spec as follows:
About 2 feet long super bright LED red light with casing.
Either in grouping of 4s or 2 lines upper & lower.
Casing with room for double sided tape.
Tq
SC, can borrow you tread ?
Anyone can recommend a decent DRL light? Budget around Rm100. Finally tempted to DIY one with on/off switch not tapping from headlight wires.
Another question, are those light on door handle legal? 2pc of white led looks good. Not too bright. I just DIY on friend's car. I told him to drive more at night and see if he got summoned by police :hahaha:.
If he get through many times, I will DIY on my car. One which turn on when we press the alarm button.

there's a few methods to doing led brake lights, one is where you put the brake on leds between the always on leds, or another one where you simply overvolt the leds. meaning one circuit is 2.5-3V on normal circuits, the other is 5V. its momentary, so will probably not hurt the LED lifespan much. But I think your superbrights aren't suited to brake lights.
Mine makes a 400ma amp draw each, (mine is bought assembled, leds are like the ones you see in torchlights) and behind the brake light lens, nobody realises its LED because its that bright.

Why DRL with switch? DRL supposed to be on when car is on, so tapping from headlights also wrong. Should tap to any wiring that have power where key is switched on....
I got mine from accessory shop. Cheap ones from China. So Far so good. RM60 per pair plus installation.
Here...Looks yellow when off
White when on
How it looks in front...
Nah, mine id DIY style, I'm just gonna do one on a board or stick.
It's gonna be messy and u will end up complaining.

Half DIY or DIY all the way bro.
If DIY all the way, just buy superbright leds.
And solder everything yourself.
Btw, the front of the car must always use white / yellow lights.
The back must be red. White at back for reverse. Signal MUST be amber.
The side, only the signal amber marker.
No other colours. Other colours are not tolerable.
Thats the normal rules. However, any creativity of the shape should be okay.
NO STUPID BLINKING LIGHTS.
Your white lights on your door handle might look pretty, but think about this.
If you were looking at this car from far, wouldn't you think it's reversing?
It's mindfu*king.

Actually got some contis with it, when you unlock car, the handles will light up for a few secs
