An arc discharge light source ( 10 ) for automotive headlight applications comprises an arc tube ( 12 ) having a hollow body ( 14 ) arrayed along a longitudinal axis ( 16 ) and provided with first and second ends ( 18, 20 ). The first and second ends have, respectively, first and second jointure areas ( 22, 24 ) with the hollow body ( 14 ). Electrodes ( 26, 28 ) are sealed respectively in each of the first and second ends ( 18, 20 ). An arc generating and sustaining medium is contained within the hollow body. a low-voltage-pulse starting aid ( 30 ) is associated with the arc tube and comprises an electrically conductive member ( 32 ) having an intermediate portion ( 34 ) and proximal and distal ends ( 36, 38 ). The intermediate portion ( 34 ) extends the length of the hollow body ( 14 ) and the proximal and distal ends ( 36, 38 ) each terminating in a loop ( 40, 42 ) comprised of a single turn of electrically conductive material. The loop ( 40 ) from the proximal end ( 36 ) surrounds the first jointure area ( 22 ) and the loop ( 42 ) from the distal end ( 38 ) surrounds the second jointure area ( 24 ).
