I want to know the answer to the following question:
What type of light is ideal for traffic signals?
All the background I'm provided with is that "One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights or lanterns (chromacity and luminance standards being set under the Convention on the International Regulations for Preventing Collisions at Sea 1972, Annex I and the CIE) and LED-based Christmas lights.". Is that enough to answer the question?
