Headlamp tsb ???

Anyone out there know of a tsb for the headlamps melting the drl lens. I can't seem to find anything in a search that has the tsb number or The part numbers for lamps.

 

N0, but mine have done the same thing on both sides. Now they are both cracked at the melted point. I just ordered new ones to replace these. I hope I don't have this same problem down the road...

 

There have been a few threads about this. I believe everyone has gotten their headlights replaced by Toyota since this only occurred on newer vehicles.

I'm not sure there was an actual TSB. My truck didn't have the issue...
