i was looking at my bulb supply for the layout and its really getting down in supply so where do you get your bulbs. i need for 022 switches bumpers and oil towers and so on.
I recommend you consider LED replacements, they run much cooler and also take a lot less power. You’d be surprised how much power all the lights on the layout consume.
led is a lot of money compared to the glass bulb and dont want to invest in the new stuff . i like the old look and the “burning of plastic” Ha HA
Try Town & Country … they stock bulbs for just about everything Lionel … standard and LED. I use LEDs on my 022s and semaphore … they run cool and you never have to concern yourself with melting lanterns!! http://www.towncountryhobbies.com/
The OP said he also wanted replacement bulbs for his oil towers. Be pretty tough to get a bubble tube going with an LED.
