Risk of accidents from exploding glass bodies and high voltage
The glass bodies of gas discharge lamps (xenon lights) are pressurised.
If the lamp breaks, the glass splinters explosively and shards scatter.
Xenon lights operate at high voltage. While changing the lamp, there is still
a danger of residual voltage discharging (electric shock) even when the bat-
tery master switch is switched off.
Have faulty lamps replaced only by properly qualified personnel who use
the relevant protective equipment.
