[NLRS] Bulbs for Kenwood TM255A

[N0DQS]

Good Morning Jon, I have a package here left over from my TM-255/455's that 
I used to use. I suspect that maybe not a good number from Kenwood anylonger 
but the part number is/was B30-0865-15 I have one bulb left and most likely 
will keep if just in case. I have used a Radio Shack bulb which is about the 
same size etc although they are 12v 60ma but I have used these also. The 
part number is 272-1092 and I think about $1.79 for a 2 pack. I guess I do 
not remember if the 255 bulb is 6v or not but of course the 12v would be not 
as bright in that case but should last a long time. Here is the link for the 
RS bulb'

 I have a Kenwood TM255a 2m multi-mode rig.  The display has lost all of its
 display lights making the LCD a bit hard to read .... especially when its
 dark.   Looking at the schematic, the bulbs are in series so I suspect that
 they are 6 vdc incandescent bulb - mechanically they are about 0.120' wide
 and 0.220" tall wire leads off the back end.

 Does anyone know what the part number of these are or can suggest a
 source ?

 I'm also contemplating switching over to LEDs, but the control circuit
 would need to change a little bit as the TM255 has an adjustable dimmer.
 That plus I would need a white LED where the light is dispersive (like an
 incandescent lamp) and not focused.
