1990 Lexus LS400 Check Engine, Bulb Failure light

Recommended Posts

 I have a 1990 Lexus LS400 and the check engine light and bold failure light is on. When I disconnect my battery to clear red I'll start the car and it won't be on it will come back on only when I step on the break when I'm stopped. But I don't have any lights I need to be replaced. Would anyone have an idea what this could be?

What is a bold ?   Did you mean bulb ?  The 2 different lights mean different things and are unrelated. Except when the brake pedal is pushed it does turn on the brake lights and also exhausts some of the engine vacuum.
