Replacement Light Bulbs for Model Trains & Accessories

Find replacement lamps for vintage and modern railroad equipment

Shop replacement model train light bulbs for locomotive headlights, illuminated passenger cars, operating accessories, and other lighted railroad features. Replacing a burned-out bulb can be a simple repair, but finding the correct lamp is important for proper fit, brightness, and operation.

Trainz carries replacement bulbs from across model railroading eras, including parts for vintage prewar and postwar trains as well as later and modern equipment. Inventory can include new and pre-owned bulbs, original replacements, new old stock, discontinued lamps, and hard-to-find lighting parts for older trains.

Where Are Light Bulbs Used on Model Trains?

Headlights, rolling stock, and illuminated accessories

Locomotive Headlights

Steam, diesel, and electric locomotives can use replaceable lamps behind headlights, number boards, and other illuminated details.

Passenger Cars & Rolling Stock

Lighted passenger cars, cabooses, and other rolling stock may use one or more bulbs to illuminate interiors or exterior lighting features.

Operating & Lighted Accessories

Stations, signals, buildings, operating accessories, and other model railroad features can use replacement lamps in a variety of sizes and configurations.

Check the Intended Application

Some bulbs were designed for a particular model or application, while others were used across multiple pieces of equipment. The individual product listing can help identify the intended use.

How to Choose a Replacement Model Train Light Bulb

Match voltage, socket, dimensions, and original part numbers

Match the Bulb Specifications

Do not choose a replacement bulb based on scale alone. Check the original lamp or equipment documentation for the correct voltage, base or socket type, bulb size and shape, and part or lamp number when available.

Voltage is especially important. A bulb designed for a different operating voltage may produce incorrect brightness or have a shortened service life. Physical clearance also matters because the replacement must fit inside the locomotive, car, accessory, or light housing without interfering with surrounding components.

Finding Bulbs for Vintage Trains

For vintage equipment, the original lamp number can be one of the best ways to identify a replacement. Older prewar and postwar trains may use bulbs that are no longer regularly produced, making original, equivalent, or new old stock lamps useful for repairs and restorations.

Because Trainz acquires previously owned model train equipment and parts, discontinued lighting components may become available as inventory changes. Check each listing for its stated specifications and compatibility.

Model Train Light Bulb FAQs

Answers to common replacement-bulb questions

What type of light bulb does my model train need?

It depends on the model and application. Check the voltage, base or socket, bulb dimensions, and original lamp or part number before choosing a replacement.

Are all model train light bulbs interchangeable?

No. Bulbs can differ in voltage, base style, size, shape, and electrical requirements even when used in trains of the same scale.

What is the difference between a model train bulb and a lens?

The bulb produces the light, while the lens is the clear or colored piece through which the light is displayed.

Yes. Replacement lamps can still be available for older equipment, including prewar and postwar trains, although some original bulb types may be discontinued or harder to find.
