JKL Components Blue Indicator Lamp 12V DC Wedge Base 10 mm Diameter LE-0503-03B

JKL Components LE-0503-03B is a blue indicator lamp engineered for reliable performance in industrial, commercial, and technical environments where effective signaling is required. Operating at 12V DC, this lamp utilizes a wedge base form factor for straightforward socket integration in automotive, instrumentation, and optoelectronic systems.

Featuring a 10 mm diameter and a length of 27.5 mm, the lamp is optimized for panel-mount and surface-mount indicator applications. Its output color is blue, achieved with a peak wavelength of 470 nm, providing clear and recognizable signaling in control panels and display systems. The lamp’s narrow viewing angle of 18 degrees allows for a focused beam, minimizing unwanted diffusion and ensuring signals are seen only where intended.

Designed for energy efficiency, the LE-0503-03B draws a nominal 15 mA, affording reduced power usage in continuous or pulsed signaling tasks. Its wedge base offers secure electrical contact with compatible indicator sockets, making it an ideal choice for both original equipment installation as well as replacement needs. The lamp is suited for use in environments such as automotive dashboards, industrial equipment operator panels, process instrumentation, and avionics systems.

Constructed to serve as a robust replacement for traditional incandescent indicator bulbs, this LED lamp delivers the added benefits of extended lifespan and reduced maintenance frequency. The available voltages, colors, and package sizes within the JKL wedge-based LED family cater to a broad selection of signaling requirements across multiple sectors.

LE-0503-03B's technical features - including its precise dimensions, low operating current, and clear blue illumination - make it applicable wherever accurate status indication, warning alerts, and function confirmations are desired. Common use cases include displays, optoelectronics, automotive electronics, aerospace panels, and industrial machinery controls.
