  sufficient. In the case of an arrangement of the part serving the control completely outside the housing of the

  lighthouse, it is necessary to have electricity

  to connect the control part to the

  used for ignition, which allow a high voltage to pass and whose path outside the headlight housing is disadvantageous for safety reasons and because of

  electromagnetic radiation emanating from them.

  Description of the embodiments

  A headlight shown in Figures 1 to 4 for vehicles, particularly for motor vehicles, has a housing 10 of plastic. The headlight housing 10

  present on its anterior extremity, that is to say

  in the direction of exit from the light 12, an opening

  which is formed by a transparent cover ice

  I0 ment 14 made of plastic or glass. The ice cream

  cover 14 may be constituted essentially as a smooth ice or have optical elements serving

  to influence the light coming out of the lighthouse. On his side

  In the interior, the headlight housing 10 has an opening 11 which can be closed by means of a cap 13 and through which the light source which will be described below can be accessed. Inside the headlight housing 10, there is adjustably a reflector 16, which has a shape appropriate to the use of the headlight and may be plastic or metal. The reflector 16

  can be rotated by means of control elements that are not

  around a horizontal axis and around a vertical axis

  to allow adjustment of the direction of the light beam

  from the headlight in the vertical direction and in the horizontal direction. In the case of the exemplary embodiment, the reflector 16 is subdivided into an upper zone 18 and a lower zone 20. The upper zone of the reflector 18 serves to produce a dipped beam light and the lower zone of the reflector 20 serves to produce a road light. In the lower zone of the top of the reflector 20,

  an incandescent lamp 22 is inserted as a source of light.

  Mière. In the upper zone 24 of the top of the reflec-

  18, a gas lamp 30 is inserted into an opening 26 by means of a lamp holder 28 as a light source. The gas luminescent lamp 30 presents

6 2704815

  a base 31, which is held in the lamp holder 28

  and a bulb 32 penetrating the upper zone of the

  flector 18 with the discharge tube. The base 31 of the gas-light lamp 30 is held in the lamp holder 28 by means of an elastic stirrup 33.

  The lamp holder 28 is in an electrical material

  trically non-conductive, for example ceramic or a plastic material and is fixed on the upper zone of the reflector 18 for example by means of screws 34 on a flange 38 surrounding its opening 26. The lamp holder 28 has a section 38 surrounding the lamp bulb 32

  luminescent gas 30 on the lower zone of its

  turn, directed in the light-output direction 12, through which the light emitted by the gas-light lamp 30 is prevented from reaching the lower zone of the reflector 20. The bulb 32 of the gas-light lamp 30 is furthermore remotely surrounded by a transparent cylinder, open at both ends 40, by which the UV fraction of the light radiation emitted by the gas-light lamp 30 is absorbed at least in part. In order to screen the light emitted by the gas-light lamp 30 directly in the light-output direction 12, a screen 42 is provided that does not allow light to pass through, which is constituted in the form of a pot. The screen 42 has an envelope 43 which surrounds the bulb 32 on its end zone oriented in the direction of exit of the light 12 and a bottom 14 which extends approximately perpendicularly to the direction of exit of the light 12 before the The screen 42 further has a spacer 45 which deviates therefrom vertically upwards, a spacer which is fixed in the upper zone of the edge of the upper zone of the reflector 18. For this purpose, the upper zone of the reflector 18 may have a groove 46 open in the direction of exit of the light 12, groove in which

  the end of the spacer 45 can be tightened.

  toise 45 also has elastic arms 47,

  shown in Figure 2, radially engaging the

  outer shell of cylinder 40, arms that come in

  taken in a groove 48 that goes all the way around the enve-

  outer lug of the cylinder 40 under elastic prestressing

  To enable the operation of the lamp

  30, it is necessary to have a

  intermediate electrical system, by which a high-voltage current from the low-voltage

  vehicle is converted to an alternating voltage. The provision

  electrical system is subdivided into a part 50 serving

  the ignition and a portion 52 for the control. The

  The ignition portion 50 is surrounded by a housing 54 made of plastic or metal and is arranged inside.

  the housing 54 of the ignition portion 50

  as shown in Figure 2, is fixed on a

  rear king 55 of the headlight housing 10 by means of screws 56.

  The casing of the ignition portion 54 is in this case disposed horizontally offset with respect to the region of the apex 24 of the reflector 16 adjacent to the opening 11 in the rear wall 55 of the housing of the 10, because at this place, the place that is available for the housing 54 of the party.servant ignition 54 is larger than directly behind the area of the summit 24. The

  ignition portion 50 is connected to the light lamp

  lighthouse 10. Electrical conductors 64 are emerging from the

  62, disposed within the headlight housing 10 of the control portion 61, which conductors are connected to the ignition portion 50. The control unit housing section 62 61

  is inserted in the direction of the arrow 65 through the opening

  63 in the headlight housing 10.

  In the case of a first exemplary embodiment shown in FIGS. 1 and 2, the section 62 presents, starting from the housing of the part 61 serving for the control located outside the headlight housing 10, a zone

  interlocking 66 with a determined cross-section.

  On the nesting zone 66 is connected a terminal zone

  67 located inside the headlight housing 10 with a larger cross section relative to the

  nesting area 66. In this way, Section 62 pre-
