The problem with robo rudolf has always been a very dim nose that was invisible during the day.

If it really is $5 & in a store 6 miles away, an RGB lightbulb for robo rudolf is going to need to happen.  It would have to be converted to 12V.  The lion kingdom doubts even a manes powered bulb is bright enough to do the job, in which case the solution would be a white manes powered bulb behind a filter that costs more than an RGB bulb.
