Default "Dial" light and battery valve radios

Hi all,

I am having a bit of fun building a battery valve radio and 'need' a dial light, I am thinking of using the 'bias derived from a resistor in the HT- lead' volts to power a couple of white LEDs in series, with a resistor added to get the volts right if needed. This arangement will give a more constant voltage than a plain resistor can anyone see any problems doing this?
