I just put on a smitty bumper on a few days ago and both lights came on. Some times you will here a "chime" and the speedometer will reduce and then recalibrate. I don't know if it has to do with the weight of the new bumper. Need some info on how to fix.

 

Why would the radio have to be reprogrammed. It works just fine. The lights are off now for the mean time. we will see what happens in the next few days.

 

I think he was talking about the presets

 

loss of power to the radio will make it lose the channel presets and time on the clock

 

I see duh

 

when i pulled my battery to do my subwoofer install, my presets stayed. the clock was not the right time, but the presets stayed. was very happy about that. battery was unplugged for like an hour.
