A lot of clock radios shake your bed there are at least a dozen types that start at around 40$.
Factory radios do not have RCA jacks on them. Only after market radios have them for hooking up external amps.

Do you mean the warning lights that tell you that the stabilizing jacks are not retracted? That would mean that one or more of the hydraulic jacks has either not full retracted, or not folded up after being retracted due to a broken or weak spring (that happened to my 1990 Pace Arrow by Fleetwood, I used a bungee to get home to get it repaired), or one or more sensors that send the signal that the jack is stowed properly and the motorhome is ready to drive is not making contact or has gone faulty. Try pushing the jacks up by hand a little after they have folded up, if the warning lights go out then you need a new spring.
Jacks are for lifting or raising things. They can be screwed jacks or air jacks, or most commonly, hydraulic jacks.
