Hi,
I've a Gen 1 MPS and have replaced all the internal globes with LEDs, and now replacing external globes too, starting with the parker + number plate lights. I've used eBay specials (but specified as Mazda 3 compatible) which do not have load resistors - I thought it wasn't an issue with Mazdas, moreso European cars.
With the parker + number plate LEDs installed, the dashboard always displays the green "headlight" icon (including when ignition off), which suggests a missing globe/error. My 7" touch panel screen no longer dims when the lights are turned on - it goes full brightness for a second then goes back to a dim mode.
Disconnected the battery for a few hours, no luck. Do I need LEDs with load resistors externally/CAN BUS compatible? Tomorrow I'll switch back to the original globes to see if that fixes the error. Should I also check the fuse box under the glovebox?
Thanks
JB
