Abstract
The antenna is produced by placing radiating elements (70) in at least one of the spaces occupied by the various vehicle external lights. The radiating elements can be dipoles formed by metallizing the lens (43) which closes the headlight casing (40) and the casing itself can be used to reflect the electromagnetic energy forwards.
