Hello guys,
I am looking for some help here regarding the really weird behavior of my front LED DRL on my 2012 IS 250. The headlights are stock from the factory, no mods or upgrades were done to the lights (or even the car, everything is stock) .
The thing is that when the headlights are turned on the original behavior of the DRL is that they slightly lower their brightness - until now everything is OK.
The issue is, that when I switch the right blinker on, both of the DRLs (left & right) fully light up and they're blinking along with the blinkers with the same frequency. It looks a little bit weird. Strange thing is, that this blinking is only for the right side blinker. When I switch on the left side blinker, the DRLs are working fine. This is when the headlights are turned on, or just the parking lights are turned on.
Here are the youtube videos of this issue, on both videos there are only the parking lights turned on to make this issue clearly visible. Apologize that there are two videos here for each side, I don't know how to cut the videos into one.
The first one is NOK - with the issue
RH blinker - NOK
The second one is OK - without the issue
LH blinker - OK
Do you guys have an idea what could be the cause of this? Has something like this happened to you? I have checked the bulbs, reset the ECU (by those two fuses) and also disconnected the battery for a few minutes but without success.
Thank you in advance for your ideas and appreciate that.
