Lose my dash and tail lights randomly in 93 Honda Civic Si?

I have a 93 Honda Civic Si and my dash and tail lights go on and off randomly i have replaced the dimmer switch and it hasn't fixed the issue. I sometimes lose my front passenger headlight. If i press on the dimmer switch its self i can usually get the dash light and tail lights to come back on. Not sure where to go from here any suggestions would be appreciated!
