Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
157 words
A light assembly for a vehicle comprising: at least one light source connected to a circuit, wherein said at least one light source has a light output adjustable according to external light conditions; wherein said circuit comprises a light switch, wherein the light output of said at least one light source is adjusted according to a selected position of said light switch; wherein said circuit further comprises first switches positioned in electrical lines connecting said light switch to said at least one light source; wherein each one of said first switches has a parallel-switched dimmer for reducing light output of said at least one light source; wherein said light switch and said first switches are connected such that when said light switch is switched on, said first switches are open and when said light switch is turned off, said first switches are closed; wherein said first switches, when closed, bridge said dimmers to increase the light output.
Claim 2
Dependent Claim
157 words
A light assembly for a vehicle comprising: at least one light source connected to a circuit, wherein said at least one light source has a light output adjustable according to external light conditions; wherein said circuit comprises a light switch, wherein the light output of said at least one light source is adjusted according to a selected position of said light switch; wherein said circuit further comprises first switches positioned in electrical lines connecting said light switch to said at least one light source; wherein each one of said first switches has a parallel-switched dimmer for reducing light output of said at least one light source; wherein said light switch and said first switches are connected such that when said light switch is switched on, said first switches are open and when said light switch is turned off, said first switches are closed; wherein said first switches, when closed, bridge said dimmers to increase the light output.

Claim 5
Dependent Claim
26 words
A light assembly according to claim 1, wherein said circuit comprises a second switch connected in said electric line to said at least one light source.
Claim 6
Dependent Claim
20 words
A light assembly according to claim 2, wherein said circuit comprises a slave controller connected downstream of said master controller.
Claim 7
Dependent Claim
22 words
A light assembly according to claim 5, wherein said slave controller controls at least one light source of a second light assembly.
Claim 8
Dependent Claim
18 words
A light assembly according to claim 1, wherein said at least one light source is a brake light.
Claim 9
Dependent Claim
15 words
A light assembly according to claim 7, wherein said brake light is comprised of LEDs.
Claim 10
Dependent Claim
19 words

Claim 11
Dependent Claim
16 words
A light assembly according to claim 9, wherein said turn signal light is comprised of LEDs.
Claim 12
Dependent Claim
140 words
A light assembly comprising: at least one fog tail light connected to a circuit; a switch for switching on and off said at least one fog tail light; an electrochromic interior rearview mirror having a sensor circuit connected to an EC adaptor, wherein said at least one fog tail light is connected to said sensor circuit; said EC adaptor having a comparator circuit, wherein said sensor circuit is connected to said comparator circuit and wherein said sensor circuit sends an actual value emitted by said electrochromic mirror to said comparator circuit for comparing to a reference value; wherein an output signal of said comparator is sent to at least one control switch for switching on and off said at least one fog tail light, wherein said control switch is serially connected between said manual switch and said fog tail light.
Claim 13
Dependent Claim
140 words
A light assembly comprising: at least one fog tail light connected to a circuit; a switch for switching on and off said at least one fog tail light; an electrochromic interior rearview mirror having a sensor circuit connected to an EC adaptor, wherein said at least one fog tail light is connected to said sensor circuit; said EC adaptor having a comparator circuit, wherein said sensor circuit is connected to said comparator circuit and wherein said sensor circuit sends an actual value emitted by said electrochromic mirror to said comparator circuit for comparing to a reference value; wherein an output signal of said comparator is sent to at least one control switch for switching on and off said at least one fog tail light, wherein said control switch is serially connected between said manual switch and said fog tail light.
Claim 14
Dependent Claim
22 words
A light assembly according to claim 11, wherein said fog tail light is turned off when a vehicle is approaching from behind.
Claim 15
Dependent Claim
14 words
A light assembly according to claim 11, wherein said comparator circuit comprises a comparator.
Claim 16
Dependent Claim
40 words
A light assembly according to claim 11, wherein said control switch is a flip-flop switch connected downstream of said comparator, wherein said flip-flop switch turns on and off said fog tail light according to said output signal of said comparator.
Claim 17
Dependent Claim
25 words
A light assembly according to claim 14, wherein said switch for switching said fog tail light on or off is activated by said flip-flop switch.
