Pic. 8.21. Removing the headlight bulb
- carefully remove the lamp from the socket, holding it by the contact leads (pic. 8.21).
When installing, do not touch the glass part of the halogen lamp with your fingers. Before installation, wipe the lamp bulb with a clean cloth dampened with alcohol. Traces of dirt and grease cause excessive heating of the lamp bulb and its rapid burnout.
Installing the lamp is carried out in the reverse order of removal. Check headlight operation.
Xenon headlights
Xenon headlight bulbs do not have a filament. Light radiation in such lamps is generated by two electrodes enclosed in a quartz flask containing a gas compressed under high pressure (xenon).
The electronic unit built into the headlight is powered by a car battery (12 V), creates a voltage pulse of 20,000 V, necessary for the ionization of an inert gas, and then generates an alternating voltage of 85 V to maintain the discharge.
All work related to the maintenance of xenon headlights is recommended to be carried out at a Renault station.
