A syringe comprising: a syringe barrel comprising a proximal end and a conical tapered distal end comprising an angled surface; and a plunger slideably disposed in the syringe barrel and configured to advance through the barrel to expel a fluid (F) therefrom, wherein the plunger comprises a transparent or translucent material configured to transmit colored electromagnetic radiation therethrough from an electromagnetic radiation source positioned below the plunger or plunger cover , or wherein at least a portion of the plunger comprises a colored material configured to reflect off a distal surface of the plunger or plunger cover axially through the syringe barrel electromagnetic radiation emitted from an electromagnetic source positioned outside the barrel to emit electromagnetic radiation through at least a portion of the sidewall of the syringe barrel toward the distal surface of the plunger or plunger cover , characterized in that the angled surface of the conical tapered distal end is configured such that an illuminated identification pattern in the form of a colored circumferential halo is formed at a predetermined portion of the angled surface of the conical tapered distal end of the syringe barrel when the syringe is filled with the fluid (F), wherein the angled surface at the conical tapered distal end of the syringe is shaped such that, when the syringe is filled with the fluid (F), at least a portion of the electromagnetic radiation is affected by an interaction of the electromagnetic radiation with at least one interface associated with the fluid (F) and the syringe to form the colored circumferential halo indicative of the fluid contents of the syringe on a predetermined portion of the syringe . a syringe barrel comprising a proximal end and a conical tapered distal end comprising an angled surface; and a plunger slideably disposed in the syringe barrel and configured to advance through the barrel to expel a fluid (F) therefrom, wherein the plunger comprises a transparent or translucent material configured to transmit colored electromagnetic radiation therethrough from an electromagnetic radiation source positioned below the plunger or plunger cover , or wherein at least a portion of the plunger comprises a colored material configured to reflect off a distal surface of the plunger or plunger cover axially through the syringe barrel electromagnetic radiation emitted from an electromagnetic source positioned outside the barrel to emit electromagnetic radiation through at least a portion of the sidewall of the syringe barrel toward the distal surface of the plunger or plunger cover , characterized in that the angled surface of the conical tapered distal end is configured such that an illuminated identification pattern in the form of a colored circumferential halo is formed at a predetermined portion of the angled surface of the conical tapered distal end of the syringe barrel when the syringe is filled with the fluid (F), wherein the angled surface at the conical tapered distal end of the syringe is shaped such that, when the syringe is filled with the fluid (F), at least a portion of the electromagnetic radiation is affected by an interaction of the electromagnetic radiation with at least one interface associated with the fluid (F) and the syringe to form the colored circumferential halo indicative of the fluid contents of the syringe on a predetermined portion of the syringe . <EOS>
