[DML] Custom LED lights - anyone interested?

Hello everyone,

I've had a lot of free time lately because of the endless cold winter here 
in Poland. So, I came up with a custom LED conversion for the door lights. I 
know that there are LED replacement bulbs available out there and they are 
inexpensive, but I never liked the way they work and look. It's usually a 
few small 3mm LEDs stuck together with a resistor to limit current. They are 
OK... but for me OK is not good enough. The resistor works as intended only 
at the voltage it was chosen for. Lower voltage will cause the LEDs to dim 
quickly, higher voltage will burn them out. Plus, they are a generic product 
meant to replace the 5W bulb in whatever light you want to use it in. Not 
for me.
I created a custom solution with a square circuit board and four LEDs with 
three LED chips in each for a total of 12 LEDs. The current is controlled by 
an IC to make sure the LEDs do not burn out and they shine with full 
brightness from 10.4V all the way up to over 30V. Even jump starting the car 
will not harm them.
The question is if there will be enough interest to start the production of 
those kits. For now I only have made one set for my own car. This is a 
prototype set to see how it works and looks. I am very happy with the 
Check out my little website and look at the pictures, read the description 
and let me know if you are interested. If we get a few people interested I 
will move the project forward. If not... My set will be the only one in 


Scroll down and click on "LED Door lights"

The kit is NOT AVAILABLE at this time. I will start production if there is 
enough interest in the product.

Disclamer - The idea for the lights, the circuit, the board layout and 
manufacturing is all done by me. The boards are manufactured by an 
electronics manufacturing company here in Poland. The LEDs and the regulator 
chip are high quality components imported from China. I chose quality parts, 
not the cheapest parts available!

At the same time I'm working on a LED conversion for the side marker lights. 
Anyone interested? I will post some pictures and description on my site in 
the next couple of days. This project will require replacing the entire 
light assembly as the original socket required only a small round hole. I 
can convert your lights or convert new OEM light for you.
Each side marker light will use 6 LEDs with 3 chips each for a total of 18 
LEDs. Total power consumption will be around 1 watt. OEM light bulb uses 5 

Let me know if you are interested.

Thank you,

Greetings from Poland!
