Help with LED Headlight Upgrade

jtheuner · 09-19-2021, 05:28 PM

I have a 2011 328 and recently upgraded my stock halogen bulbs to LED bulbs however they are flickering slightly with the engine running. I have put the car into Accessory mode with the engine off and they stay on solid without any flickering at all. Any idea what would cause this? I have Carly and have already disabled all bulb checks and the new bulbs came with Canbus decoders but still having the issue only when the engine is running.

Its probably the LED bulbs then, I've had no issues with the common ones i've purchased.

I installed the morimoto 2 stroke 3.0 in both regular and high beam, and they work perfectly with no flicker. These bulbs have the benefit of being able to function at a reduced voltage and will therefore work as DRL. Very happy with this set up; they provide great output with a stock beam pattern.
