When power to the distribution buses falls below 20 V.
Which cockpit lights are not integrated into the dimming functions of the cockpit lighting controls?
The lights in:
- The Engine Fire Handles, and
- The Engine Fuel Control Switches
Due to the critical nature of the annunciations these lights always illuminate at full bright levels.

What is required for either the LOGO lights or the ICE Inspection lights to operate?
At least one generator must be on line.
- Beginning with S/N 2086, these lights can be turned on with battery power only.
When do the landing lights automatically extinguish?
At 18,000 feet
> This prevents bulb failure caused by thermal shock at high altitudes.
> On descent through 18,000 feet, the landing lights automatically illuminate if the flight crew has left the switches in the ON position. (OM 2A-33-50, 2F)
> The PULSE feature remains operable above 18,000 feet.
When will the PULSE mode for the landing lights automatically activate?
When a Resolution Advisory (TCAS) is annunciated.
What must be true for the taxi lights to operate?
The nose landing gear must be extended and locked - the taxi lights extinguish when the landing gear is retracted, even if still selected ON (the ON legend in the switch also automatically extinguishes).
