Hi SCOUTSOUT2000_IN_AK
The 1PN58 should use a white /clear bulb, you will not see red through this scope as the image you are seeing is projected on a small tv screen that only shows green, i dont think it is possible to see a red reticule through it. did your 1PN58 come in its metal transit case with all accessories? i am after the 1PN58 model now as i already have the rarer NSPU.

Yes a single lamp is used to light the whole rangefinding reticule, i own an original PSO-1 scope, it only cost me £36 in total.
i now have several spare bulbs, they are all of the original 2.5v incandescent bulb type and they are in their original cartridges too.
