[QUOTE=whiteis33;9863954]Hey there whiteis33! I have a 2018 IS350 and I had those exact pair of OEM JDM spec triple beams imported from Japan, had them professionally installed, and oddly enough, despite the fitment and wiring being very self-explanatory, everything worked except the high beams. When I press the left stalk the high beam icon even turns on, yet the bulbs don't. There are no error messages on the dash either. Do you have any input or advice as to the best way to fix this issue? Any info would be appreciated! Thanks!

 

Having issues with mine as well. I ordered off Alibaba with the ballasts they sent me and I installed them and low beams and high beams don’t work at all, only the blinkers.

So I switched the ballasts to the opposite headlights to see if that would work and no luck.

The guy also sent me a video of them working before he shipped them to me, so I’m not sure what’s going on.

I installed my stock ballasts and that worked but I only have low beams, no high beams.

the guy that sent them to me said I need to have the headlight program upgraded 🤷🏻‍♂️ I’ve never seen anyone have to deal with this before.

Any advice?
