So I installed some Led headlights on my 92 ls400 and I noticed that the high beams wouldn't work. They only work when I remove one of the led lights and install one of the factory lights but when it has both LEDs high beams won't work. What could I do for the high beams to work with the LEDs?

Why must everything be so difficult. Good luck.

Make sure you have purchased LED bulbs that have a dual-brightness kind of chip in it. Some cheaper LED bulbs only have one light setting- so when you turn on the highs, they won't do anything. Make sure they specifically mention that they also work as highs. If they function with one halogen bulb installed, it could be a resistance problem. Have a local auto electric shop wire up some resistors or get one of those easy bolt-on resistors from eBay/Amazon so your LED bulbs will work properly.

i also suspect you have single "filament" LED bulbs, since the low beam always turns off when the high beam is triggered to save the bulb.
