I just had a new stereo installed in my 99 Accord EX. I noticed that night driving home the clock light was not on as it normally is when I turn the headlights on. I took the car back to the shop where the stereo was installed. They pulled out the clock and made sure the 2 plugs were attached properly and they were. The clock keeps time and the hazard light button next to the clock works so they are claiming it's not there problem. Is there a light bulb of some sort in the clock? I'm gonna take the car to my mechanic for it's 75000 mile tune-up and have them check it out. Maybe this was just a coincidence that the light went out the same day the stereo was installed? Maybe not???? Rick
