I have a1970 olds cutlass and I added LED headlights. When I press the switch for the high beams to come on the low beam goes out. This happens just on the drivers side. Any help would be greatly appreciated.

 

It sounds like the high-beam LED circuit on your driver's side outer (low beam) bulb isn't working. Try swapping low-beam bulbs. If the problem moves w/ the bulbs, you have a bad bulb. If the problem remains on the driver's side, look for some bad wiring on the high-beam circuit and/or connector. Check the grounds too.

 

Thanks
