I need to control 3 - 5 strands of LED rope light using amperage insufficient to power all of them simultaneously. Here's the master plan... Use my Raspberry Pi Pico to switch between them rapidly. I figure 0.01 of a second illumination followed by 0.04 of a second darkness should make it look like they're all illuminated. Rather than using transistors to drive relays I figure a set of mosfets might do the job better. Here's the thing though I need some help. My electronics is virtually non-existent. The lights are 12v, 5A. Which mosfets will handle that and what resistor etc do I need?

I'd use a Darlington like the TIP120. This should help ...
