Led reflector headlights

[Brandon2344]

i have fitted the led reflector headlights they work really well other than the headlights dimming When the stop start system was engaged and the engine stopped (at traffic lights), after a few seconds of the engine stopping, the LEDs would actually get brighter by approx 10%, then, when the engine restarts, after approx 5 seconds, the leds would then dim back down about 10%. I have this on camera and can replicate every time. I've no idea what causes the issue or why it does this, I would have expected it to be the opposite (brighter with the engine running!). Maybe its a coding thing?.
