Using a Bulb lamp on the EQD The Depths?

[Atodovax]

And we're not examining the actual Univibe LFO (or another pre-existing LFO that uses an incandescent bulb) because...? 

Well the thing is this. I have the EQD Depths PCB BOard already populated and just wanted to use it with a bulb lamp for the sake of MOJO hehe.. Its just that. And i was looking for an "easy" implementation to modify the LFO but keeping most of the board populated. I have built several univibes using different layouts and i didnt realize that THE DEPTHS  uses a different LFO or at least has a different aproach and is acommodated for an LED.
I found some little 6volt lamps online and was wondering how would they work replacing the LED. Im not sure how much miliamps this lamp needs to light up , since the seller doesn´t know..
