Lo-Voltage Lamp Driver (LVLD)

Back to AO Services HOME page


This product was originally designed to replace the Norton Commando 'warning light simulator', where it could use the standard Lucas 'idiot' warning lamp. The state-of-the-art encapsulated device can be readily used in many other automotive application and battery warning applications.


The lamp will illuminate when the ignition is on and will extinguish when the engine has started and the battery voltage rises.
This device will drive a standard automotive instrument lamp (up to 3W). The potted construction is vibration resistant and designed to be electrically robust. The nominal switching point is set at 12.5V, with about 250mV of hysteresis built-in to provide positive switching.
