I recently purchased the light string shown he

The hope was to replace existing 120 V lamps in window candles with an LED
light from the string, but I am having some difficulty. As I suspected when
I cut off one of the lights from the string and, still fused, plugged it
into the 120 v outlet, the fuses blew. So, it looks like a voltage drop is
needed. The total voltage/ current of the entire 25 bulb string, according
to the link above, is 0.027 amps (3.24 watts) @ 120 V. A tag on the string
says that each bulb is 3.1V @ 0.062 amps. So, which approach is best:

1) Use a dropping resistor for each bulb I want to use? What value and
wattage if so? Would the resistor stay cool enough to hide it in the
candle?

2) Use an AC plug in the wall type transformer (rated for 3.1 V AC), which
I assume would be quite hard to find because most of them are DC (I tried
placing 3 V DC across the LED lamp and it didn't work)?

Appreciate any help here. The candles I placed in the windows recently all
use what I thought were cool, smaller standard 120 V incandescent bulbs but
there was enough heating to discolor the window blinds they are up against.
The wife liked the "warm white" of the LED string, so I wanted to replace
the incandescents with those and I also want to use a much thinner power
cord to the candles if possible, something I couldn't really get away with
using the higher powered incandescent.

Thanks,
