I just bought a 99 honda accord and the dash lights along with the tail lights do not work but the brakes still work what can the problem be?

If the dash lights don't come on, replace the ignition switch and harness:

Well I was having the same problem that u were having and I took my car to my mechanic he checked all my fuses and it was as simple as the main headlight switch. It fixed everything, the no dash lights and no tail lights. Great thing about it is the part that solved all my problems was $19.98 or around $22.00 after taxes
