Hello guys I've searched all over for a solution but I think this is rare. My 08 LR3 runs perfectly until I turn on the headlights. When I do that I get all the usual stuff suspension lowered, transmission fault,brake light, ect ect. Any suggestions on this particular incident. There was flooding due to a warped cowl but been dry for weeks and the headlight on looks to be the only problem. Thanks again

 

Have you confirmed your battery and alternator are good? Could easily be a voltage drop issue.
