Frequently Asked Questions
How does the BA15d base differ from standard bayonet indicator lamps?
The BA15d base features a 15 mm diameter brass collar with two opposing locking pins and two isolated solder contacts on the bottom insulator. It differs from single-contact bayonet bases (BA15s), which route one side of the electrical circuit through the brass shell.
Can this lamp run directly on standard 120V AC line power?
Yes. The lamp is designed for direct 120V line operation and draws 50 mA without requiring an external dropping resistor or step-down transformer.
How do you confirm this bulb matches an existing 6S6 socket?
Check the base contacts and diameter. A 6S6DC uses dual solder contacts on the base bottom (BA15d) with a 15 mm collar, distinguishing it from miniature candelabra screw base (6S6/E12) or single-contact bayonet (6S6/SC) lamps.
Indicator bulbs are the quiet sentinels of the equipment rack - when this one glows, you know power is right where it needs to be. Push and twist it into the bayonet socket to get that front panel back in service.
