Hello there everyone.
I got my R125 about a month ago and I decided I'd like to modify the backlight of the speedometer after I saw one modified in a video right here (0:18 - 0:21).

I bought SMD 3528 Blue LEDs off ebay and I swapped the original ones with the lovely blue LEDs.
I noticed something very weird happening and this is the reason for me creating this thread. I swapped all LEDs related to the backlight of the screen and tachometer. It turned out that all of them were glowing but very dimly. I decided to start again and swap one LED at a time. I numbered the LEDs on the picture right here
When I replaced LED 1, everything was great. It was very bright and everything seemed to be okay. Then as I was very impatient I swapped LED 2,3 and 4. Here is the result
As you can see LED 1 and 4 are very dim. LED 2 and 3 are good. LED 5 and 6 are okay (they haven't been swapped) but as you can see on the picture they are dimmer than LED 7 and 8.
I decided to take the voltage readings and here they are:
LED 1 = 2.46 V
LED 2 = 2.90 V
LED 3 = 2.90 V
LED 5 = 1.78 V
LED 8 = 1.87 V
My question is what can I do to make all LEDs glow bright? Is the resistors beside LED 1, 4, 5 and 6 that need to be replaced/removed? (There are no resistors at LED 2 and 3 and the voltage is high and consistant) Maybe it's something else?
I tried to contact the guy that made the video but i had no response, that's why I'm posting here.
(I know the soldering isn't perfect and that i didn't clean the flux off.)
Thank you for checking this thread out.
