a eclos modifications may be resorted to which fall ny o t latest yp automotive Ve cles within the scope of the claims appended heret have the lenses of their head and tail lights flush In the drawing: 35 with their supporting fenders. Some of these Figure 1 is a fragmentary side elevation, with lenses are circular in outline, while others are parts broken away and illustrated in section, of Sq a o rectangular. A li h ly odified form one form of the invention applied to a, headof the invention iS illustrated in Figures 3, 4 and light; to provide for the blackout of these lenses.

Figure 2 is a front elevation of the attachment 0 In Figure 3 of the drawing e e iS S own at shown in Figure 1; lens I! flush with the forward end of the fender Figure 3 is a fragmentary side elevati of l8 and substantially rectangular in outline. The fender in which a headlight is supported with at h H to be applied for b o t purits lens flush with the forward end thereof; poses to this lens I! comprises a sheet 20 of Figure 4 is an levati n of n form f th flexible opaque material and of the same conattachment adapted to be applied to black out tour as the lens. The sheet 20 is Provided W th a lense of the flush type shown in Figure 3; and a Substantially rectangular Opening M and with Figure 5 is an elevation of a slightly modified

slits

22 and 23 Slightly longer than the Op n n form of the attachment illustrated in Figure 4. 7 2| and parallel to the sides thereof. These slits In the form of the invention shown in Figures r eive the opposite sides or ed f the trans- 1 and 2, the black ut attachment, designated a lucent colored sheet 24 which therefore forms a a whole'by the reference numeral 6, comprises Closure r the Opening a sheet I of flexible material impervious to light The back of the sheet 20 is coated with a rays and provided with an aperture 8 illustrated uita l dh v y in the pa su und n as substantially rectangular in outline, but 5 the portion of the back designed to receive the inserted ends of the closure sheet 24. A backing sheet 25 is applied, in the usual manner, to the adhesive coating to preserve it in tacky condition until the user desires to apply the blackout attachment to the lens H. A tab 26 is secured to the backing sheet 25 to facilitate removal thereof from the sheet 20 when desired.

The form of the invention shown in Fig. is structurally the same as that shown in Figure 4, but is circular in outline and obviously intended for use on a flush lens having a similar outline. This modified form comprises a circular blackout sheet 21 having a central aperture 28, of substantially rectangular outline, and slit 29 and.

30 parallel to the sides of said aperture to receive,

when desired, the opposite edges of a translucent colored sheet similar to sheet 24 of Figure 4,

The back of the sheet 21, in the annular space 3| around the circle 32 which bounds the aper-,

ture 28 and slits 29 and 30, is provided with an adhesive coating for applying sheet 2! to a flush lens. An annular backing 32 is applied to this adhesive to preserve it in tacky condition until the user desires to apply the blackout sheet to the lens; and a tab 33 is secured to the annular backing 32 to facilitate removal of the backing sheet fromthe blackout sheet.

It is obviously immaterial whether the translucent colored dimming sheet be applied to the front or the rear'face of the blackout sheet to form a dimming closure for the aperture therethrough. Where the rectangular frame' I3 is used, as in Fig. 1, the mounting of the frame on the rear face'of the blackout sheet will make a neater article. In the forms of blackout sheets using slits on opposite sides of the central aperture, the insertion of the opposite edges of the translucent closure sheet through the front face of automobiles, it must be understood that it may be employed in any connection where it may be found useful.

What I claim is:

1. A blackout attachment for lamps, compris ing a sheet of flexible opaque material adapted to be applied to the light-transmitting face of a lamp and having a light-transmitting aperture therethrough, said sheet being provided with slits at opposite sides of said aperture, a light-dimming sheet of translucent material having its opposite edges inserted through said slits and I held thereby against said aperture to form a dimming closure therefor, and means at the periphery of'said sheet for detachably connecting the attachment as a whole to the light transmitting face of said lamp.

of the blackout sheet will make a better appearr ing article, and will eliminate the possibility of damage to the edges of the closure sheet, which would otherwise project through the front face of the attachment.

While the attachment has been described as being designed for useon the head or tail lights 2. A blackout attachment for lamps, comprising a sheet of flexible opaque material adapted to be applied to the light transmitting face of a lamp and having a light transmitting aperture therethrough, said sheet being provided with slits at opposite sides of said aperture, a light-dimming sheet of translucent material havin its opposite edges inserted through said slits and held thereby against said aperture to form a lightdimming closure therefor, one face of said opaque sheet being provided at its periphery with an adhesive to be applied to the said face for securing the attachment as a whole detachably to said face.

3. The blackout attachment set forth in claim 2 in combination with a protective backing applied to said adhesive to preserve the tackiness thereof prior to the application of the attachment to said light-transmitting face.

'4. The blackout attachment set forth in claim 2 in combination with a protective backing detachably applied to said adhesive to preserve the adhesive qualities thereof prior to the application of the attachment to said light-transmitting face, and a tab secured to said protective backing to facilitate removal of the backing from said adhesive.
