Align each dome to its own LED zone

Mark the centerline and height of each LED zone, along with the space between them. Identify whether each dome must be viewed alone, with both zones lit, or under both conditions.

Check the bridge and seating edge together

Identify the visible bridge between domes and the retaining edge around the part. On a fitted sample, record any shadow at the bridge separately from gaps or movement at the housing interface.

Buyer questions

Can both domes use the same finish?

Provide the reference finish and the desired appearance for each lit zone. Confirm the result with trial parts on the intended board.

How should we check the bridge if each zone is switched separately?

Define the view and drive setting for each switching state. Record when a bridge shadow or cross-zone glow is acceptable to your project.
