2003 Honda Odyssey DLR (canadian vehical)

Not all the time but most times when the van is started I hear a muffled noise (sort of a buzzing)comming from an area to the leftside beneath the dash against the fender wall (where there is a lot of wiring etc.) When the noise is there my right side drivers running light is not on, sometimes it goes off by itself after a few minutes, today it didn't go off untill I hit my Hi beam switch then the DRL lights both worked, the buzzing stops and the DRL notification on my dash then goes off and all is normal. With my headlight switch on all lights work OK so I dont think that its the bulb. Any ideas? Thanking you in advance
