The opaque portion 40 comprises a light guide 50, wherein the light guide 50 is configured to transmit light from the light source to the illuminable portion 30. The light guide 50 is configured such that light may pass directly from the light source, and be emitted by the illuminable portion 30. The light guide 50 is not visible to the user of the vehicle 100, and is configured to enable the illuminable portion 30 to emit light for observation by the user of the vehicle 100. The light guide 50 is formed from a plastics material, such as polycarbonate, and is configured such that the light emitted from the light source 70 is guided through the opaque portion 40 to illuminate the illuminable portion 30.
As shown in figure 5, the illuminable portion 30 comprises a blade portion 550 configured to protrude into the opaque portion 40. The blade portion 550 of the illuminable portion 30 is shielded from the view of the user by the opaque portion 40. The blade portion 550 is configured to maintain a connection between the illuminable portion 30 and the opaque portion 40. The blade portion 550 is configured to act as the light guide 50.
The illuminable portion 30 may comprise a light obscuration region 60 so that the light, when emitted, has a non-uniform appearance. The light obscuration region 60 may be formed by coating a portion of the illuminable portion 30 with an opaque material, such as a paint or ink. Alternatively, the light obscuration region 60 may be formed by etching or engraving the illuminable portion 30.
The light obscuration region 60 may be an indicator indicative of gearshift direction selectable by operation of the gearshift paddle. In embodiments where different paddle of the plurality of gear shift paddle 300 are operable to perform a gear shift in a given direction, the indicator may be a plus symbol (+) to indicate a shift up or upshift on one of the plurality of gear shift paddle 300, and the indicator may be a minus symbol (-) to indicate a shift down or downshift on another of the plurality of gear shift paddle 300. In embodiments where different directional actuation of the plurality of gear shift paddle 300 is utilised in order to determine the directionality (i.e. upshift or downshift), the indicator may comprise a plus symbol and a directional arrow, for example, and a minus symbol and a directional arrow, for example. The directional arrows in embodiments represent the direction in which the gear shift paddle 300 must be actuated by the user of the vehicle in order to request the desired gear shift. The directional arrows in embodiments represent directions substantially opposite to each other.
As discussed, in embodiments, the light source is an LED 70. The LED 70 may be contained within the opaque portion 40, or may be contained within the illuminable portion 30. The LED 70 is configured to provide light to the light guide 50, which will transmit the light, such that the light is emitted through the illuminable portion 30 for observation by the user of the vehicle 100.
The illuminable portion 30 is configured to selectively illuminate in dependence on a given vehicle drive mode. That is, the light source is configured to provide light of different colours to the illuminable portion for observation by the user ofthe vehicle 100. The light source is configured to provide light of two colours (referred to as a first colour and a second colour), at least.
