my answer is NO, NOT on 78 models. as far as i am aware the first PE's with blinkers were the 79 'N' models sold in NSW. other states followed soon after that. the bikes only would of had blinkers fitted from factory. they required extra wiring, different stator, a battery, different lever perches, and brackets on the frame for rear blinkers. i find it hard to believe that suzuki australia would of modified standard 78 or 79 bikes once they got here so they could run blinkers. they would not of gone and welded brackets on the frame for the rear blinkers and welded brackets for the battery holder. that was all done at japan. by the time the rules required blinkers suzuki AUS would of send a list of requirements to japan and the bikes came out here all set up with blinkers on them. the 79 models had blinkers from the factory, well at least the ones sold in NSW but im yet to find a aus spec 79 brochure showing blinkers and i doubt they would of brought out one brochure specifically for NSW. 1980 was the first year all states got blinkers on PE's and i have many brochures of the australian spec PE's of 1980 showing these fitted
