I was trying to replace the incandescent flasher bulbs in my PinBot with LED's but I ran into a bit of a problem. Before I go any further I just want to clarify, and correct me if I am wrong, there are SIX flasher bulbs and THREE flasher circuits, each circuit powering TWO bulbs in PARALLEL (unlike Bally's three-in-serial). So whenever a flasher is activated during game play 2, 4, or all 6 flashers will always light at a time.

This is what happens when I attempt an LED replacement on one of the flasher circuits:

1) If both bulbs are incandescent, all works fine.

2) If one bulb (either one) is incandescent and the other is an LED, it works fine.

3) If on bulb base is empty with no bulb installed and the other bulb base has an LED, the LED is permanently lit (maybe slightly dimmer than when activated during gameplay).

4) If BOTH bulbs are LED, both LED's stay permanently lit just like in scenario 3 above.

It is the same for all three circuits, so I ended up having one LED and one incandescent in each circuit since this is the only way it would work. Is this normal or is there something I should suspect is wrong with my machine? I apologize if this has already been addressed in a previous thread.

Thank you!
