When I got the car it had led's installed map trunk ect, I seem to have the hyper flash issue. for a week or so it was a map light then i noticed the rear was doing it but seems the map light has stopped hypering.. I found some post about that happening when starting but not much more. anyway

wrong bulbs maybe ?
please don't tell me i need resistors to stop it
what bulb is mostly used? (part number please)

Its late im lazy and didnt search much but hey im honest
