⇒ Rocket should remain lit on the ground post-landing

⇒ Lighting requirements for low power rockets:

⇒ Glow sticks are allowable as primary lighting up to “B” impulse due to low light output, but can be supplemental lighting “C” and above

⇒ Phosphorescent / glowing paint is supplemental lighting only

⇒ All segments of rocket have independent lighting (i.e. nose cone, av bay, airframe, etc.)

⇒ Redundant lighting is suggested
