Pedometers usually use button cell batteries which only support rather low current draws.

Adding a LED would increase current draw and potentially quite a lot if they skimped on the current limiting resistor to get a short but bright flash.

A lot of sustained activity (hopefully not the kind adults would engage in to get the wrist working) could lead to the battery over heating.
