How to Add Directional Headlights and Tail Lights to a Train

Placing Exterior Light Blocks

Before turning your build into a moving train, place your light blocks directly onto the exterior ends of the train structure:

1. Position light fixtures on the front of your locomotive facing forward toward the track.

2. Place corresponding light fixtures on the rear car facing backward.

3. Ensure all fixtures are attached directly to the train structure blocks while the train is still unassembled.

Assembling and Testing Directional Lights

Once the light fixtures are placed, assemble your train at a train station block to activate the contraption.

1. Interact with the train station block to assemble the train contraption.

2. Enter the conductor seat and drive the train forward along the tracks.

3. Observe the front fixtures: they will project bright white beams along the railway tracks to illuminate the path ahead.

4. Reverse your travel direction. The fixtures automatically switch based on movement—the front-facing lights become red marker tail lights, while the fixtures facing the new travel direction switch to bright white headlights.
