I have an '04 Accord Coupe EX V6 that has a small LED that appears to be mounted to a small bracket, located on the underside of the dash on the LH side. This LED has started flashing twice at all times - on or off. Feeling around the LED it has a spring loaded pushbutton on the back side - I'm thinking it's a reset of some kind - but pressing/holding it does not stop the flashing. I am not the original owner and can't find ANY info on the web about what this might be. Any thoughts??

 

Sounds like an aftermarket alarm or something. Said another way, as far as I know, there were no under-dash LEDs of any sort on the 2004 Accords.
