The T5 LED Signal Lamp with twist lock socket holder is a compact 12V indicator lamp for dashboards, instrument clusters, gauge backlights, and panel indicators. The twist lock base holds the lamp firmly in place and makes swapping simple, with no soldering or cutting needed.

It is a modern LED replacement for common T5 sub-miniature wedge bulbs such as the 37, 73, 74, 17, 18, and 70 types. The LED draws only about 15mA, runs cool, and is rated for over 30,000 hours, so it outlasts a filament bulb and puts far less heat on the board around it. LEDs are polarity sensitive, so if the lamp does not light, simply turn the socket 180 degrees.

Besides vehicle dashboards, it also works well as a bright, low-power indicator in 12V DIY projects, control panels, boats, caravans, and model builds. It is a practical, budget-friendly choice for hobbyists, makers, and anyone repairing a worn dash lamp.
