i used to have a 2007 is250 and i bought vland headlights and tailights for it and it looked great. i was wondering if there are aftermarket headlights with triple beams for a 2015 is350 similar to vlands. or does anyone know if 2019 IS triple beam headlights will fit on my 2015 IS? i havent seen much aftermarket lights for my vehicle

 

I can see why you would want to replace the dusty headlights from the 2nd gen IS but there's really no need for the 3IS nor are there aftermarket options from what I am familiar with.

You can upgrade to the triple beam, I've seen some people have some finnicky issues which I'm sure can be ironed out but you would need to upgrade your bumper to the face lifted 2017+ IS model because the triple beam housing won't fit on the bumper

 

Also the Main Body ECU will be throwing warning messages with the newer headlights.
If you change the Main Body ECU to the newer one, that will correct it, but if you have Factory Fog Lights those will stop working.
