Railway C-more dot dim

Can a diode wear out.  With a new battery the dot is not a bright as it used to be... indooors it would be so bright you could not see the target without dialing it down.   now at full bright setting can see target fine and outdoors in bright light can lose dot on white target.    Just  wondering if they can lose brightness over time or could there be a problem with the circuit board not getting enough voltage to the diode.   Any ideas?

This one is four or five years old and I shoot matches almost every weekend plus weekly practice nights at club.   Looked a friends last night and looking at the diode directly ( not at the glass)his gets much brighter when the brightness control is turned the last 1/3 of the turn.    Will replace diode and see if that solves problem.      Thanks
