Hello, M3 Fighter Pilots!!
I got a "LED Center Stopping Lamp".
I decided to install it to my M3 Coupe, like this.
It has 12 LEDs. Its diameter is 3mm.
In order to get more brightness, I changed these 3mm LEDs to 5mm LEDs.
This is still in progress. Compare the brightness.
Left side is 3mm LEDs (Normal Intensity), and right side is 5mm LEDs (Ultra High Intensity).
When turn on the small lamp, it gleams with its 30% brightness.
When turn on the stopping lamp, it gleams with its 100% brightness.
And in order to notice immediately, I added a LED flashing circuit.
It looks like "F1 Center Stopping Lamp", doesn't it?
