    I'm doing a small project and I was wondering if there was any possible way to replace NE 2 neon lamps with LEDs.

    Depends on the circuit. We do not allow LEDs connected to mains (live AC voltage) on this site. However, if you show us what you are trying to do I am sure we can help.

    That's a little vague!

    The 2 devices have wildly different voltage requirements, you can get LEDs that work as low as 2mA, which is in the ball park of the heavier rated neons.

    You'll need a voltage dropper, and if you're running it from AC; you'll need to either use an inverse parallel pair of LEDs or a single LED with an inverse parallel 1N4148 to protect it from reverse breakdown.
