I THINK you twist the cap on the bottom where the microswitch is slightly and it comes off. I'm not near my cab right now or I'd go verify it for you.
BINGO!
Thanks Cot. For anyone else who searches this topic:
Remove the microswitch
Twist the bottom piece a smidge counter-clockwise, small click may be heard
Pull with a little pressure and mechanism with light will come out allowing nut to be removed
Reverse to re-attach.
Thanks Cot. Didn't want to force it not knowing what was supposed to happen. Woot!
Can't connect them at the moment however as wife playing Robotron. Gah!
