Approximately 2 seconds after firing, the delay element ignites the ejection charge/candle. The ignition charge ignites the illumination candle canister. The ejection charge ejects the parachute/candle assembly out the front end of the projectile. The parachute deploys upon ejection and provides visual light for approximately 45 seconds while descending.
