10 Cent Coins: Defects, Errors, and Value

Sorry about that...

But still, let's continue with the topic...

Today, I removed the circuit and installed a 300-ohm resistor and a 4.7k potentiometer. The lamp had stopped working again after just two days.
So, with just 300 ohms, the car vibrates a little bit when it's standing still, but there's no warning light .

A test drive and turning the gear a little... I think the fog light was still on on the way back .

Excellent fog machine (I fix the settings with a switch).


Okay, I can increase the voltage up to 4.7k without any issues. However, I need to do a proper test drive (accelerating, shifting gears, and holding the wires together at the resistor and potentiometer is a bit much for the driver alone). Just kidding. After a successful test drive, I will report back. I always appreciate hearing about other experiences with the Volvo 850 TDI or the Audi A6, 100, etc.
