Part Vital circuit that measures lamp current and drops the proving relay if the displayed aspect fails, forcing approach signals to a more restrictive aspect. · View page · History
This page is for disagreements and questions about Lamp Proving Unit: a part that does not belong, a quantity that looks wrong, a photo that shows the wrong thing, a claim that needs evidence. Norms that emerge here become the house style; if discussion deadlocks, a reviewer or the admin decides. If you already know the fix, edit the page directly instead of asking permission.
