An external beacon 305 and method of determining the location and/or orientation of a vehicle, comprising emitting light, e.g. from a light source in a projector 328, to illuminate a target 388 on the vehicle; capturing an image, e.g. using a camera 368; analysing the captured image to identify the target 388 and using this to determine the location and/or orientation of the vehicle. Also claimed is a system and method of determining the location and/or orientation of a vehicle including emitting light in an encoded pattern and analysing the captured image to identify an image element that matches the encoded signal in order to determine the vehicle location/orientation. The beacon may be a portable parking beacon used for assistance in parking a vehicle 302 with a trailer 303. The beacon may include an optical guide (330, fig. 24) which is controlled to perform a scan, e.g. a vertical or raster scan using a laser diode, in order to illuminate the target. The projector may generate a parking location indicator and may be used to facilitate automatic parking while avoiding obstacles 383, e.g. near a mains electrical connection 382 (e.g. as shown in figure 26).
