Difficulty: Medium

Notes: While this block is of importance, and I would love to add it. It is very difficult to make (especially if I attempt to avoid using redstone). This will be staying in consideration for now.

Minimum features are features required before I will release this to the public. Recommended features are goals/ideas I would love to include for this item.

Minimum:

• A block capable of changing between a red/green light based on redstone or other input.
• Signal light visibly glows (has constant brightness despite external conditions).
• Stand/gantry for signal.

Recommended:

• Ability to kill signal (disable all lighting).
• Can display a yellow light in addition to red/green.
• Emissive block.
• Preferably stackable (can place multiple signals on top of each other).

Difficult:

• Capable of compliance with NORAC Signal Rules (for example, being able to displaying a flashing state for each light as well as being able to display red/yellow/green states).
• Find alternative to redstone to provide more realistic feel.
