My usage of this modified telephone mount has the telephone level to the ground.
In that orientation the two white T-1 3/4 LED lamps are pointing down. A better orientation would be for those lamps to be pointing forward.
The mount has been modified by me to change from two white T-1 3/4 through hole LED lamps pointing down to a single white 1206 SMT LED lamp pointing forward.
Electrical measurements showed the two existing T-1 3/4 LED lamps shared 10mA of forward current.
The 1206 SMT LED lamps I selected are rated at 20mA forward current, maximum, so I used only one part instead of two.
Both white T-1 3/4 LED lamps were removed. The long leads on those through hole parts had a 90° bend so they would protrude through the housing.
A single 1206 SMT LED lamp was soldered onto the PCB pads. A new hole was drilled in the housing above that SMT lamp.
Now the white light is shining forward. My plan is to use this in fast blink mode.
