Hello! If i swap out the LEDs on my Panzer III for smaller 3mm LEDs will a different resistor be needed. Anyone know? Many thanks.

If they are the same colour LED's then they will be alright, the size makes no difference as I have 3mm, 5mm and 10mm white LED's that all run at the same forward voltage, its changing the colour that causes problems as different colours run at slightly different voltages.

Cheers fella!

I replaced the original 5 mm leds on my H.L. Panzer IV and Pershing ; by 3mm flat top "warm white" without changing the resistors..
The "warm white" gives you a color closer to the real thing than the "white" ...
Here's some pics :

I have to say that the 'warm white' does look great! I'm going to order some!
