2005 instrument lights

i was just gifted a 2005 Tundra, and i need to know about silly little things that the haynes manual does not cover... like instrument lights. i am pretty sure that i don't have the scrap the whole truck because the high beam indicator is burned out or a turn signal indicator doesnt work. i have already had to deal with the non-existent gasket between the muffler and the pipe it slides over that is 2.38 inches in diameter and the only gaskets listed for are 1.92" or 1.96" or 2.45"...

 

never mind. thanks to all of the "help", i have since learned some of what i needed to know from a ford mushtwang owner.
