I have 1978 fJ40 that I have replaced all my tail light (turn, brake and reverse) with LED...two bulbs on my instrument cluster and the heat / defrost indicator light and dash light with LED. I am having issue with when I press brake pedal before turning it on the instrument panel and heat/defrost indicator light and dash light come on. Also the parking lights come on. When driving and I turn the left turn signal it will only work when I don’t have the head lights on or the brake pedal pushed in. Also my right turn signal light does not come on all the time when I turn it on and the high beam lever can be tricky...have to play with lever to keep high beams on. I have a lot going on...could switching out incandescent bulbs for LED be causing the issue...perhaps grounding issue in brake light...or issue with turn signal relay on column. Frustrating...thoughts?
