Question:
I have a 2021 Jeep Wrangler Unlimited with Park Assist. An installation video said something about smart diodes. Can you recommend a product for the tail lights that protect the electrical system and dont activate the Jeeps ECU every time the tail lights go on? Thanks.

Expert Reply:
Michael, since your Jeep has the park assist then you are going to need the Roadmaster Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RM47ZR.
This kit is going to ensure that your LED lights function as they should while being towed, will prevent electrical feedback, and includes two smart diodes, a wiring harness, a split loom, ring terminals and zip ties,

The tail lights have a circuit that notifies the ECU if a lamp is out. When the tail light is lit, it sends a signal to the ECU and wakes it up. If the circuit is not interrupted, the battery on the Jeep goes dead in a typical towing day.
