park & brake lights don't work

What is your question?

My park lights and my break lights don't come on I can push the button and nothing happens and the low beam lights don't work at night I only have high beams @

What makes this problem better or worse?

nothing now use to blink in and out

How long has your 1999 Buick LeSabre had this problem?
