Abstract:
A signal display lamp (1) including: an LED-mounting substrate (2); and a lens unit (3) having an insertion space (41) for housing at least some of the LED-mounting substrate (2) and having a prescribed length in the axial direction (X). The lens unit (3) is used connected in the axial direction (X) to another lens unit (3) of the same shape. The lens unit (3) includes a pair of insertion space-forming members (40). The pair of insertion space-forming members (40) partition the insertion space (41), between the facing surfaces (40A) thereof. End sections (40B) of the pair of insertion space-forming members (40), in the axial direction (X), are elastically deformable and, as a result of entering between other end sections (40C) of a pair of insertion space-forming members (40) of another lens unit (3) in the axial direction (X), approach each other and sandwich the LED-mounting substrate (2) from the thickness direction (T).
