www.trainboard.com/railimages/data/510/thumbs/F3_light_board_effects_003.JPGMade up a few headlight boards for WPDIVWDR. Used circuit board so the resistors are out of the way mounted on the front, the top light is .680 from bottom of slot/board, the headlight fits perfect in the circuit board holes matching the shell.
All sodering is on the back side covered with caplon tape. Common leads (blue wire can be jumped across both bulbs so only one blue go's back the board
What I like about this is that the number boards can be on a separate light function rom the headlight, other the F4, as that is the Rule 17 dimmable light.
