A vehicle lighting unit can be configured to allow the brightnesses of light observed through vertically arranged lenses to substantially match when the lenses are viewed from a certain viewpoint in front of the vehicle. In some embodiments, the battery demonstrate an accessible current capacity of at least about 220 mAhg when pulsed in groups of four constant energy pulses at a current density of 30 mAcm2 to deliver 50 Joules per pulse. In particular, an antenna comprises at least a ground plane, a radiating element, a short, and a feed tab.
