One of our customers bought the LED bulb 9006 for the low beam on his 2005 Jeep grand Cherokee, the bulbs fitted well and worked great. However, he found these LED bulbs flicker while engine running and headlights turned off, so he bought a pair of canbus resistors from our store.
We have not heard of any one experienced the same issue before and were unsure if that canbus resistors work, so we sent another resistors together and told the customer to try one by one.
After this customer received the resistors and tried both of them, he told the one with gold heat sink fixed the issue.
So if you experience the same issue on Jeep grand Cherokee, then you can buy the canbus resistor from here:
