I have a 2001 #586 and I've read my user manual and there isn't any instruction on how the docking lights work.
I see there is a docking light switch on the dash. I toggled this and they did not light. I suspect you must be in reverse to have them come on but cannot find anything that tells me so. If they are inop I want to fix them before I go on my trip to NY this summer. 
What are the correct sequence of steps to get them to light?
Thank you,
Hank

Switch on, ignition on for my rig.

Highly likely the light bulbs themselves are kaput. Very high vibration area where they are mounted.

Try switch on, ignition on, and check voltage at one of the lights. There is also a fuse in the passenger foot well panel.

Thank you Richard. With your instructions I was able to verify the docking lights both work. They seemed dim in the bright Florida sun. I'll check them another time when it is dark out. I think they wouldn't drastically blind a driver next to me if I inadvertently switched them on.

Originally, the bulbs in mine were PAR 36 100 watts. I replaced with LED lights that are worthless. I see now that LED PAR 36 bulbs are available. Be careful with the rubber boot. I ripped one of mine and never found a replacement.
