Lighting apparatus for a motor vehicle having a daytime running light illuminated at different levels
First Claim
1. A lighting apparatus for a motor vehicle comprising:
- a daytime running light device;
a light beam device; and
a drive device operable to drive an illumination level of the daytime running light device, wherein;
the drive device is operable to drive the daytime running light device so as to have a first illumination level with the light beam device switched off,the drive device is operable to drive the daytime running light device so as to have a second illumination level with the light beam device switched on and,the drive device is operable to drive the daytime running light device so as to have a third illumination level with the light beam device switched on with poor weather conditions,wherein light beam device is a low-beam device, a high-beam device, or a low- and high-beam device,wherein the second illumination level is less than or equal to the first illumination level, andwherein the third illumination level is less than the second illumination level.

Abstract
A lighting apparatus for a motor vehicle includes a daytime running light device, a low-beam, high-beam, or low- and high-beam light device, and a drive device operable to drive an illumination level of the daytime running light device. With the low-beam and/or high-beam light device switched off, the drive device drives the daytime running light device so as to have a first illumination level. With the low-beam and/or high beam light device switched on, the drive device drives the daytime running light device so as to have a second illumination level. With the low-beam and/or high-beam light device switched on and with poor weather conditions, the drive device drives the daytime running light device so as to have a third illumination level. The second illumination level is less than or equal to the first illumination level. The third illumination level is less than the second illumination level.

11. A method for operating a lighting apparatus, the method comprising:
-
driving an illumination level of a daytime running light device using a drive device so as to; drive the daytime running light device at a first illumination level when a light beam device is switched off, drive the daytime running light device at a second illumination level when the light beam device is switched on, and drive the daytime running light device at a third illumination level when the light beam device is switched on and there are poor weather conditions, wherein light beam device is a low-beam device, a high-beam device, or a low- and high-beam device, wherein, the second illumination level is less than or equal to the first illumination level, and wherein the third illumination level is less than the second illumination level.
