Not sure what you'd call them, but my guess is that they contain an LDR (light dependent resistor) and a light bulb or LED for a light source, like an opto coupler type thing i guess  !@# probably used to simulate a gunshot or explosion perhaps ??  #@#

I've seen a similar thing in old guitar amps for the tremolo circuits  *%*

we have a winner  $#$  $#$ $#$ $#$

well done. 6 volt lamp on one side and an LDR on the other and yes they help control the explosion sounds.

and i don't know what they are called either.  !@#  !@)


Yay i won  #*#  whats my prize for winning  ??  :lol :lol
you have won 100 either 44 or 555 black lights, they all have a high quality black and silver coating guaranteed to stop any light leaving the lamp but you will still have full heat output from most of the lamps.  :lol :lol just send $500 "in good faith" so we can send your prize out quickly
