A common problem with the Daytime Running Light (DRL) module in many 90’s Honda vehicles is cold solder joints at the relays in the control module. These develop over time, and cause sometimes intermittent issues with running lights. I encountered this problem, which would usually present itself on mornings with lots of dew, and would fix itself sometime during my commute to work. Rather than pay a mechanic to repair or replace the module, you can do it yourself with some basic tools.
A Google search will reveal many forums and sites with instructions to fix this problem: here are the two links which I consulted prior to performing these repairs.
