Devices and Methods for Controlling Vehicle Lights
First Claim
1. A method of operating a run/brake light, first turn light, and second turn light of a vehicle, the method comprising:
- receiving a brake signal;
responsive to the brake signal, illuminating the run/brake light and the first and second turn lights to display a first pattern that extends across each of the lights;
while still receiving the brake signal, receiving a first turn signal; and
responsive to the first turn signal, changing the operation of the first turn light from displaying the first pattern to displaying a second pattern while the run/brake light continues to display the first pattern.

Abstract
A control circuit for operating the lights of a vehicle. In one embodiment, the rear lights of the vehicle are controlled by the control circuit. The control circuit illuminates two or more of the vehicle lights in a common pattern to indicate a specific vehicle operation. When the vehicle simultaneously performs two operations, the controller may transition the lights to illuminate in different patterns to clearly indicate the separate vehicle operations. The controller may further provide for adjusting the light intensity of one or more of the lights. The lights may be adjusted to have a similar intensity to prevent confusion when the different lights are used in combination to indicate a vehicle operation.

1. A method of operating a run/brake light, first turn light, and second turn light of a vehicle, the method comprising:
-
receiving a brake signal; responsive to the brake signal, illuminating the run/brake light and the first and second turn lights to display a first pattern that extends across each of the lights; while still receiving the brake signal, receiving a first turn signal; and responsive to the first turn signal, changing the operation of the first turn light from displaying the first pattern to displaying a second pattern while the run/brake light continues to display the first pattern. - View Dependent Claims (2, 3, 4)

5. A control circuit that operates first, second, and third vehicle lights, comprising:
-
an output stage including a plurality of switches to selectively operate the first, second, and third lights; and a controller configured to control the output stage to illuminate the first, second, and third lights, the controller being configured to; operate the plurality of switches to display a first pattern on the first, second, and third lights responsive to receiving a brake signal and a lack of a turn signal; and operate the plurality of switches to display the first pattern on the first light while displaying a second pattern on the second light and a third pattern on the third light with each of the patterns being different, responsive to receiving a first turn signal while also receiving the brake signal. - View Dependent Claims (6, 7, 8)

9. A method of operating a run/brake light, first turn light, and second turn light of a vehicle, comprising:
-
configuring the run/brake light to be illuminated at a first intensity when the vehicle is in a run state, the first intensity being less than a full intensity; receiving an input adjusting an intensity level of the first and second turn lights in the run state, the input being received during a program mode when the vehicle is not in operation; and thereafter, determining that the vehicle is in the run state and operating the run/brake light and the first and second turn lights and displaying a first pattern that extends across each of the lights, the intensity of the first turn light and the second turn light being substantially the same as the first intensity. - View Dependent Claims (10, 11, 12)

13. A control circuit to operate first, second, and third lights of a vehicle, comprising:
-
a controller configured to receive a brake signal, a turn signal, and one or more user inputs; the controller configured to display a brake pattern on each of the first, second, and third lights in response to receiving the brake signal and, responsive to also receiving the turn signal, to display the brake pattern on the first light, and a second pattern on the second light; the controller also changing the third light to have a different visual appearance than each of the first and second lights responsive to the receiving the brake signal and the turn signal; and the controller configured to display a run pattern on each of the lights when the vehicle is in a run state with the first light at an intensity less than a full intensity and the second and third lights being substantially the same as the first light intensity. - View Dependent Claims (14, 15, 16, 17, 18)

19. A control circuit that operates a run/brake light, a first turn light, and a second turn light of a vehicle, comprising:
-
a controller; a user interface with one or more input mechanisms to submit a first input to the controller to select one of a plurality of lighting patterns and a second input to adjust an intensity level of the first and second turn lights in a run state, the controller configured to receive the inputs when the vehicle is not in operation; an output stage including a plurality of switches to selectively operate the run/brake light, the first turn light, and the second turn light; and the controller operative to receive the inputs from the user interface and control the output stage to illuminate the run/brake light, the first turn light, and the second turn light, the controller being configured to; operate the plurality of switches to display a selected one of the plurality of lighting patterns on the run/brake light, first turn light, and second turn light in response to receiving a brake signal and a lack of a turn signal; operate the plurality of switches to display the selected lighting pattern on the run/brake light while displaying a second pattern on the first turn light and a third pattern on the second turn light, responsive to receiving a first turn signal while also receiving the brake signal, each of the patterns being different; and determine that the vehicle is in the run state and display a second pattern on each of the lights with the run/brake light being illuminated at a first intensity that is less than a full intensity and the intensity of the first and second turn lights being substantially the same as the first intensity, the intensity of the first and second turn lights being based on the second input. - View Dependent Claims (20, 21)
