  Figure 9 shows in section a last variant.

  In Figure 1, there is shown in perspective an indicator 1 of a motor vehicle signaling light.

  the, the latter being disposed in front of a light source35 and having, when this source is not switched on, a continuous degraded appearance from one end la towards $ one end lb, the end la being darker than the end lb. The indicator is colored, for example, in red, amber or any other color. In the embodiment of FIGS. 1 and 2, the sight glass is formed by a translucent colored plate 1

  in the mass and having, at one end la, a thick

  sor "L" which decreases towards the other end lb, the thickness "1" of this end can be of the order

  1 mm, while the thickness L can be 3 mm.

  In the embodiment of Figure 3, the indicator is formed of three sections of translucent plate 2, 3 and 4, made, for example, in polymethyl methacrylate. The first plate has, at one end 2a, a thickness "L" greater than that of its end 2b. The plate 3 is connected at its end 3a to the plate 2 by a recess, the thickness of the plate 3, at the right of the recess, corresponding to

  the thickness "L", while the other end 3b has a thickness "1".

  The coloring of the plate 3 corresponds to that of the end 2b of the plate 2.

  The end of the plate 3 is connected by tapping at one end 4a of a plate 4, the thickness of this end corresponding to the thickness "L", while the thickness of the other end 4b corresponds to l 'thickness "1" .35 The coloring of plate 4 corresponds to

  the coloring of the end 3b of the plate 3.

  Thanks to this arrangement, a degraded appearance of coloring of the plate is obtained from the end 2a towards the end 4b. Next to the plate 2, a lamp 5 is provided which corresponds to a signaling light, the plate 2 having a colorimetry such as that provided for by the regulations. There is a partition Sa at the junction of the plates 2 and 3 so that

  the plates 3 and 4 are not lit by the lamp 5.

  An embodiment is shown in which three plates are provided, but it is possible, depending on the desired effect, to provide more than three plates arranged

end to end.

  In this embodiment, the internal face

  plates 2, 3 and 4 has no optics.

  In FIG. 4, another embodiment has been represented.

  in which the indicator light is formed by a light screen-

  tinted or colorless 6, for example polymethacrylate

  of methyl with returns 7 at its ends.

  The screen 6 is molded onto three plate sections 8, 9 and 10, each of the three plate sections,

  on the internal face, respectively having go-

  drons 8c, 9c and 10c. Plate 8 is uniformly colored

  and has, at its end 8a, a thickness "L" greater than

  re at that "1" of its end 8b, the plate 9 at its

  end 9a has a thickness "L", while its extremi-

  tee 9b has a thickness "1", the plate 10 also having a thickness "L" at its end 10a which decreases

  towards its other end 10b (thickness "1"). The gulls 8c, 9c and 10c can be longitudinal or transverse

  saux. The plate 9 has a coloration corresponding to that of the end 8b and the plate 10 a coloration corresponding to the end 9b. A lamp 11 is arranged opposite the plate 8, a partition 11a extending to the right of the end 9a. In Figure 5, there is shown in section another alternative embodiment. In this embodiment, a slightly tinted or colorless screen 15 is overmolded

  on three translucent plates 12, 13 and 14 and colored.

  The plates 12, 13 and 14 are provided, on

  their internal face, of an optic, for example of lens

  12c, 13c and 14c, these can be spherical, cylindrical, prismatic or be formed of catadioptric prisms.

  The plate 12 has a thickness which decreases

  health from its end 12a towards its end 12b ("L", "1"), the internal face of the screen 15 having, in line with the end 12b, a recess 17 in which comes

  lodge the end 13a of the plate 13, the end of which

  tee 13b is located at the right of a recess 18 into which the end 14a of the screen 14 is inserted. Thus the indicator light,

  on its internal face, presents a continuous curve.

  A lamp 16 is arranged behind the plate 12

  and a partition 16a is provided to the right of the end 13a.

  As in the previous embodiments, all the plates have a thickness which decreases from the ends 12a, 13a and 14a towards the ends 12b, 13b and 14b and the coloring of the plate 12 corresponds to that of the end 12b of the plate 12, while

  the coloring of the plate 14 corresponds to that of the end

miter 13b of plate 13.

  In FIG. 6, a variant is shown with three sections of translucent colored plate 21, 22 and 23 which are arranged end to end and which provide a slight space between them so that an overmolded screen 20 forms two ribs 24 and 27 , the rib 24 having,

  on one side, a shoulder 25 and, on the other side, a bulge

ment 26.

  The rib 27 is formed in the same way and has, on one side, a shoulder 28 and, on the other

opposite, a bulge 29.

  The screen 20 has edges 20a and 20b and the end 21a of the plate 21 has a thickness

  "L" greater than the thickness "1" of the end 21b cooperates

rant with shoulder 25.

  On the swollen part 26 to the shoulder 28

  extends the second plate 22 having, at its extremi-

  tee 22a, a thickness "L" greater than that "1" of its end 22b. Finally, from the bulge 29 extends to the edge 20b of the screen 20 the third plate 23 having, at its end 23a, a thickness "L" greater than that "1" of its end 23b.25 Plate 22 has a corresponding coloring

  to that of the end 21b and the plate 23, a coloring corresponding to that of the end 22b.

  The internal face of the plates 21, 22 and 23 comprises

  optics such as prisms, gadroons or lenses respectively 21c, 22c and 23c and possibly

of catadioptric prisms.

  To the right of the rib 24 extends a partition a and opposite the plate 20 which has the colorimetry corresponding to the regulations is arranged a bulb 30.5 In Figure 7, there is shown an alternative embodiment in which the indicator is formed of a single translucent plate 41 whose thickness increases from one end 41a to an intermediate point 10c 41c to decrease to the other end 41b. The plate is made of a colored plastic in

  the mass and it is only the different thickness which gives an impression of color gradation from point 41c to the ends 41a and 41b. The plate 15 may include an optic and possibly overmold a screen.

  FIG. 8 shows another embodiment in which the sight glass 31 is formed by four sections of

plate 32, 33, 34 and 35.

  The plate 33 is colored and translucent and its end 33a has a thickness "L" greater than its other end 33b. The end 33a is integral with one end 34a of the plate 34 which has a thickness

  "L" greater than that of its other end 34b.

  The plate 34 is colored and translucent and has a color identical to that of the plate 33.

  The end 33b of the plate 33 is integral with the end 32a of the plate 32, the latter having

  at its end 32a a thickness "L" corresponding to the thickness of the end 33a, which thickness goes down

  tending towards the end 32b which has a thickness

  "1" corresponding to that of the end 33b.

  The plate 32 has a corresponding coloration

at that of the end 33b.

  The end 34b of the plate 34 is integral with the end 35a of the plate 35, this end 35a

  having a thickness "L" corresponding to that of the extremi-

  tees 33a and 34a, while its other end 35b has a thickness "1" equal to that of the ends 32b, 33b and 34b, the coloring of this plate 35 corresponding to

that of the end 34b.

  Opposite the ends 33a and 34a extends a lamp 36, partitions 36a and 36b being arranged on either side of this lamp.15 The colorimetry of the parts of the plates 33 and 34 delimited by the partitions 36a corresponds to that

prescribed by regulation.

  The various plates 32, 33, 34 and 35 comprise, on their internal face, an optic respectively 32c,

33c, 34c and 35c.

  In this variant, we obtain a gradient

  colored from the ends 33a and 34a to the ends 32b and 35b when the fire is out.

  FIG. 9 shows a last embodiment of the same type as that of FIG. 7, but in which

  on plates 32, 33, 34 and 35 is overmolded a colorless or slightly tinted screen 40.

  Of course, the invention is not limited to the embodiments which have just been described and

  represented. Many modifications of detail can be made without departing from the scope of the invention.
