When I try to start my trans am I hear a clicking noise and I see this red light that says brake what does it mean

 

that could mean anything from your battery being dead to someone having stolen your engine , and your just gonna have to lift the hood and check .

Ok , so looking in there , IS there an engine ? If yes , and since we know there is a battery because things do light up and click , next up would be to get a set of jumper cables & a running car and give it a proper jump . Does it start ? If yes the two most likely suspects are the battery or the alternator , just don't forget there are several lesser seen causes as well that could cause it to need a jump so don't just run out and replace either the battery nor the alternator till proper troubleshooting tests actually prove one or the other to be defective .

PS , Welcome to TGO

 

Clicking noise is starter so look there first...test the voltage on the purple wire going to s terminal on starter .... battery voltage would help to know too

 

Tried to jump it yesterday and nothing happened the light just popped up the same as before

 

Have you even checked the batt voltage? It may need a deep charge.A very discharged or dead will need more than a jump start.
