LED Tail light and license plate issues

has anyone faced this problem with their e39 m5? changed the OEM tail lights and the license plate lights to LED bought off Ebay. installation was easy and connection was easy too. but noticed that that led lights for both the tail light and the license plates keep flickering every ten seconds. searched around and found out that installing load resistors will solve the flashing flickering lights. However, it did not change anything.

the reason for those to flash every ten seconds or so is because the system is checking for any burned bulbs and since the led draw little amps, it keeps flickering. however, when turning the switch lights on, everything seems fine and no flashing. so i am driving the car day and night with lights on as it is really embarrassing to drive at day light and the beast acts up as it looks cheesy :0

anyone had this problem and solved it or reached to a conclusion? it has something to do with the LCM i guess. any techies out there tried to bypass that checking ecu thing?


cheers

That is the car checking that bulbs haven't burned and since LED need way more power/current to work they flicker if these do not have efficient resistance. maybe you need to code the car for the taillights and need to get a new pair for the license plate that have inbuilt resistors. Mine are fine on the license plate, but they have in built resistors which keep the check license plate light error messages away. just my 1 euro.

thanks reekoon, one told me that i need to install the led license plates while it is running ?????? this should eliminate the flashing!!!
done that but nothing happened.
so u are suggesting i get new led license plate lights? mine came with error free msg. not sure how to solve this

might be that there are inbuilt resistors on the bulbs them selves, but they are too small so they keep flickering. Also i dunno no what year your car is and is license plate light check enabled on all models/years or only on facelifts e.g.

mine look like this
