LED interior light bulbs

xEDDIEx · 08-10-2020, 05:09 AM

Recently Im trying to change all my halogen light bulbs into LED.

For reading lights, glovebox, footwell and door lights, I managed to change all of them. But I noticed that 1 (or 2) reading light/ dome light bulbs occasionally cannot be turned on with the engine running for a few moments.
If I turn the engine off, then all the reading light/dome light bulbs are working just fine.

It feel like I cannot have so many LED bulbs connected all at once while the engine is running. Is that just because I did not install the "Error free canbus" LED bulbs?
(But it seems that the "Error Free" bulbs cannot fit as the PCB is quite thick)

I think it has to do with the voltage change from car on to off. Better bulbs may resolve, I can't say with certainty.
I have a similar issue with my dome LED only, doesn't bother me all that much but it's there.

I recently did the same thing in my car, replaced all interior bulbs with LEDs. I used the Ziza Kit from ECS Tuning - <https://www.ecstuning.com/b-ziza-parts/master-led-interior-lighting-kit/335ledint~kit/>

no issues for over 300 miles so far.

Maybe try replacing the bulbs with Ziza ones, they are a good bulb company.
