25.8. Bulbs of internal lighting
Before replacement of a bulb of external lighting remove a weight wire from the accumulator. Remember that if the bulb just burned, it can be too hot.
Before replacement of a bulb of external lighting check the corresponding electric chain and a safety lock. Do not concern a glass flask of a lamp barehanded. The fingerprint evaporates and besieged on a reflector therefore lighting worsens. Surely replace the failed lamps with lamps of the same type. Wipe the spots arising on imprudence from touches with a pure dewaxed rag or alcohol.
