Component identification
(1/1)

Hi guys,

We have some battery LED uplighters at work which are used for architectural lighting and two have very corroded PCBs!

There are 3 small components that I am having trouble identifying. Printed to the board is D1, D2, D3 so are they just diodes?
On one PCB they are marked YP 11A and on the second PCB they are marked YP 19A…

Bit of a stupid question but what are they? One has fallen off the PCB tracks and I am gonna attempt to repair…  :-//
