Yeah you should be fine with all your lights on, I actually took an old Hyundai there and it had the SES light on and it passed. They just plug in the ODBII in and then immediatley it failed the test, so they just ask you if you want to continue with the test...Of course I do I drove there right? So they just hook up the good 'ol sniffer and I passed so it was good for another 2 years. You should be fine Fredo...
