Question: I have a pair of your 2017 36" light bars. They both stopped working and you guys kindly shipped me 2 replacement ballasts for the 2017s along with 2 new OR90s I purchased.
Was there a different ballast used on the 2017 models? Because the new ballasts worked from a few hours to a few weeks on the 2017 light bars and now neither are working. The leds all worked great, so I assume its a ballast issue? What can I try next? Thank you.
