12-Volt Emergency Light Bulbs – Replacement Lamps for Code-Compliant Fixtures

12-Volt emergency light bulbs are high-demand replacements for commercial-grade exit sign lights, emergency lighting units, and combo signs. Built to operate on 12V battery systems, these lamps are essential for restoring brightness and runtime in older or hardwired emergency setups. Every model is UL 924 certified and meets NFPA 101 life safety code requirements for egress path illumination.

These 12V replacement bulbs are commonly found in high-output exit signs and emergency light heads, particularly in buildings with extended runtime or dual-circuit requirements. Choose from wedge-base, bayonet, sealed beam, and LED options to match your fixture’s specs and restore full performance. Whether you’re performing annual maintenance or replacing burnt-out lamps after a safety inspection, our 12-volt selection makes it easy to keep your system compliant.

If your fixture is aging or inefficient, it may be time to upgrade the unit entirely. Or, for areas where electrical wiring is difficult to maintain, explore non-powered exit sign alternatives like glow-in-the-dark egress signage or radioactive-powered signs for a no-maintenance solution.

FAQs About 12-Volt Emergency Light Bulbs

Where are 12-Volt emergency bulbs typically used?

You’ll find 12V lamps in medium to high-capacity emergency lights, exit sign combos, and remote lighting heads. They’re especially common in industrial and multi-story buildings that require broader coverage and longer battery runtime.

How do I match a replacement 12V bulb?

Check your old bulb for voltage, wattage, and base type—usually printed on the lamp body. Then match those specs to a UL-listed replacement. Be sure the socket and overall bulb size are compatible with your fixture’s housing.

Do 12V emergency lamps support UL 924 and NFPA 101?

Yes. When installed in a compatible fixture, all our 12-volt lamps meet UL 924 and NFPA 101 emergency egress lighting requirements, including the 90-minute battery runtime standard.

Is it worth upgrading to LED?

If your fixture supports it, upgrading to a 12V LED bulb can improve light quality, reduce power draw, and last significantly longer than halogen or incandescent options. Many LED bulbs are direct plug-in replacements.

Can I mix different bulb types in the same fixture?

It’s not recommended. Stick with the same type and wattage for consistent light output and proper battery usage. Mixing LED and incandescent bulbs may lead to uneven performance or premature failure.

Are there non-electric alternatives to exit sign lighting?

Yes. For areas where power is unreliable or wiring is cost-prohibitive, self-glowing exit signs using tritium gas, or light-activated signage offer code-approved illumination with zero maintenance.
