Replacement of lamps

Filament lamps fail eventually. Therefore each 2 years they should be replaced on new even if they still keep the working capacity. It does not belong to halogen lamps which, for example, are applied in the main headlights. As a rule, a resource them much higher and to replace them follows only at failure. Easing of force of light in filament lamps is determined by black adjournment on a glass flask.

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. Spots arising on imprudence from touches wipe pure not a fleecy rag or alcohol.

At replacement of xenon lamps it is necessary to be very attentive and careful as from the power supply of these lamps it is possible to receive strong blow a current.

Replacement of gas-discharge (xenon) lamps which it is possible to determine by a sticker with a sign of a high voltage on the lamp case, it is not recommended to make independently.


In H7 filament lamps an elevated pressure and they can burst at replacement therefore at replacement of these lamps it is necessary to put on gloves and goggles.
