I went to change a bulb in my instrument panel and i decided to change all the bulbs to amber color bulbs. I put the panel back in and drove it all gauges works great. I find out that night that not only the bulb that was originally out is still out but every one expect for the one behind the higher numbers on the speedo is out. Also when my seat belt is not pulled up far enough it will keep on ringing, even in parked. Is there any one that know what might of shorted out? I would like the lights fixed so I could see my RPM's at night but I have a long driveway and can't take seat belt off at the top now b/c of noise.

Thanks.
