An exit sign with emergency lights combines two life-safety functions in one fixture: an illuminated exit sign and adjustable emergency light heads. For many commercial spaces, that combination is the cleanest way to mark an exit and provide backup lighting near the door during a power outage.
Combo units are popular because they can reduce wall clutter, simplify product selection, and sometimes lower installation cost compared with mounting a separate exit sign and a separate emergency light.
What is an exit sign and emergency light combo?
A combo unit includes the exit legend, internal electronics, a rechargeable backup battery, and two or more emergency lamp heads. Under normal power, the exit sign remains illuminated. When power fails, the battery powers the sign and emergency heads for the required backup period.
You can compare options in combo exit signs, including low-profile exit combos, wet-location exit combos, NYC-approved exit combos, and Chicago-approved combos.
When a combo unit makes sense
Choose a combo when the exit door also needs emergency illumination. This is common near exterior doors, suite exits, warehouse exits, back-of-house corridors, retail stockrooms, offices, restaurants, schools, and small commercial buildings.
A combo unit can be especially efficient when the electrical box is already located above the exit door. Instead of wiring and mounting two separate fixtures, the installer can often use one fixture to satisfy both exit marking and nearby emergency lighting needs.
When separate fixtures are better
A combo is not always the right layout. If the exit sign needs to be visible from one direction but the emergency light needs to cover a different area, separate fixtures may provide better coverage. Large open rooms, long corridors, or spaces with obstructions may need dedicated emergency lights placed away from the exit sign.
Also consider mounting height and beam direction. Emergency heads need to aim at the walking path, stairs, changes in direction, or equipment areas that require illumination.
Battery backup matters
Most combo units include a battery backup system. During an outage, the battery keeps the sign and light heads operating long enough for occupants to exit. Always check the listing, voltage, and backup duration required by your local code.
If you only need lighting without an exit legend, shop emergency lights. If you only need the sign, compare LED exit signs.
Red or green lettering?
Combo exit signs are commonly available with red or green lettering. The correct color depends on your project requirements and local preference. If you are replacing existing fixtures, matching the current sign color is often the simplest path unless your inspector specifies otherwise.
Bottom line
An exit sign with emergency lights is a smart choice when the exit location also needs backup illumination. It keeps the installation compact and helps buyers avoid mixing incompatible fixtures. For most standard commercial exit doors, start with combo exit signs, then choose the housing, face style, and letter color that match your location.
