Are Resistors Needed?
Hello,
I am doing a custom install in a LEGO MOC locomotive. I am using a PF rechargeable battery box for power. I am using a Model Rectifier Corp Loco Genie DC/DCC board for motor, sound, and light control. I will have 8 Brickstuff warm white LED's, 4 for forward, and 4 for reverse. The Loco Genie board has directional control for the lights. The Loco Genie paperwork says to install 750 ohm resistors if using 1.5v LEDs. The PF Rechargeable battery box is set to full voltage ~7.4v to allow the Loco Genie board to have full power for motor, sound, and light control. Do I need to add resistors between the Loco Genie light output, and the Brickstuff LEDs?
thanks,
Sak

Thank you both for the quick answers. Just to make sure, this resistor world be suitable to wire between the Loco Genie output and 4 LEDs? https://www.digikey.com/en/products/detail/vishay-beyschlag-draloric-bc-components/MBA02040C1200FCT00/5062234

Sal Ciofani Sure, or you could get away with an even smaller/less expensive resistor: https://www.digikey.com/en/products/detail/stackpole-electronics-inc/RNMF14FTC120R/2617285.
