Miniature Incandescent Light Kit

The EDWARDS-SIGNALING 2705W24V is a miniature incandescent light kit designed for low-voltage signalling and indicator applications. It suits technicians and maintenance teams needing a direct replacement bulb with a double contact bayonet base. The unit operates on 24V AC supply and draws 5 W of power.

Thermals Noise and Power Draw

As an incandescent source, the bulb generates noticeable heat during continuous operation and has a rated life of 2,500 hours. It starts reliably at temperatures down to -22 degrees F and carries CE and cULus safety certifications. The lamp is not dimmable and produces a standard white light output.

Replacement and Upgrade Context

This kit replaces failed BA15d base incandescent bulbs in existing 24V AC fixtures and panels. The jump is worth it when the original lamp has reached end of life and a certified, direct-fit replacement is required. It does not suit buyers who need dimmable control or longer-life LED alternatives.

Questions about this item

How do I install the BA15d base bulb, and which step do people get wrong?

Align the two pins on the BA15d base with the slots in the socket, push straight in, then twist until the pins lock; the common mistake is forcing the bulb without twisting, which bends the pins.

What maintenance or replacement will the 2705W24V kit need later?

The incandescent bulb is rated for 2,500 hours of operation; after that period the filament will fail and the bulb must be replaced.

What limit appears first under sustained use of the 5 W, 24 V AC bulb?

The 2,500-hour rated life is the first limit reached; continuous operation will exhaust the filament before any thermal or voltage threshold is hit.
