2022 Cherokee Trailhawk with Roadmaster smart diodes
Recently finished setting up a new 2022 Cherokee Trailhawk (not Grand Cherokee) for flat towing. For the lights I installed the Roadmaster Smart Diode system. After hooking up to the tow vehicle I went to check the lights on the Jeep. Since the sun was shining on the lights I leaned down & shaded the tail lights. I noticed a buzzing sound coming from the tail lights on both sides. This only occured when the running lights were on, not with the brake lights or turn signals.
When unplugged from the tow vehicle, there is no buzzing when the Jeep running lights are turned on. So it appears that the buzzing is caused by the Smart Diodes when towing with the running lights on. The buzzing is definitely coming from the tail lights & not the Diode packs.
Anyone else have a similar experience?
