Field worker,
Just do it.
I can vouch for Pelican products being damn near indestructible. I have a super saber light that was run over by a fire engine and still works. I have had various models of their flash lights to a depth of 90 feet. I have beaten and abused their cases beyond belief. They have survived bumps,falls, slides, skids and throws while keeping the contents contained and dry.
If you want the 1550's to more closely match your bikes paint you can "flash" them with a propane torch and paint them .
The computer I am typing this on is sitting on a Pelican1660 right now.
