How long is a piece of string?
An 0.2 Watt (6V x 0.034A = 0.2 Watts) incandescent is an indicator bulb. Or a pretty crappy torch.
You've got 6V.
Most indicator-type LEDs are good for 10mA. A red LED will drop ~1.6V+.
If you use a 470R resistor you won't get more than 10mA. 4.4/470 < 0.01.
If it's a green LED, 390R.
If it's a blue LED 330R.
Make sure it's a 10mA LED, some are 2mA.
