Refresh miniature panel illumination with these wired incandescent bulbs for instrument clusters, speedometers, automatic climate control panels and radio lighting. They are designed for compact low-voltage applications where a small amber lamp is required, with a choice of body diameter and operating voltage to help match the existing fitting.

The bulbs are available in 3mm, 4mm and 5mm diameter options, with 3V, 6V, 9V, 12V and 24V voltage choices. The selected option contains 50 mini bulbs, each with two wire leads for connection within the relevant instrument or switch assembly. The illumination colour is OEM amber, providing a warm display colour for suitable dashboard and control-panel applications.

For accurate physical matching, the 3mm bulb body measures 3mm in diameter and 8mm in body length. The 4mm version measures 4mm in diameter and 10mm in body length. The 5mm version measures 5mm in diameter and 12mm in body length. These measurements refer to the bulb body and do not include the wire leads.

Operating voltage is covered from 3V to 24V, with a stated operating current range of 40-80mA. Lead length and current depend on the selected diameter and voltage. For example, the 3mm options use 10mm to 26mm leads, the 4mm options use 8mm to 26mm leads, and the 5mm options use 12mm to 26mm leads. Current ratings range from 0.04A to 0.122A across the available combinations.

Please check the original bulb diameter, body length, voltage and lead arrangement before ordering. Select one diameter and one voltage option, then use the matching specification details to ensure the bulbs are suitable for your instrument cluster, speedometer, climate control or radio lighting application.
