The Pertronix LU-149 Ignitor is a points-to-electronic ignition conversion kit for early British four-cylinder engines using the Lucas DM2 series distributor, found on cars such as the MGA, Mini, Triumph TR4 and Austin Healey Sprite. It replaces the points and condenser with a maintenance-free magnetic-trigger module for reliable starting and a stronger spark. The kit runs on a 12-volt negative-ground system and installs inside the original distributor.

FAQ
What does the Pertronix LU-149 Ignitor kit do?
It converts the original breaker-point ignition to electronic. The Ignitor replaces the points and condenser inside the existing distributor with a self-contained magnetic-trigger module, so the engine starts more reliably, holds timing better, and needs no points to clean, gap or replace.
What does the Pertronix LU-149 fit?
It is designed for Lucas DM2 series 4-cylinder distributor (British). Fitment is determined by the distributor, so check your distributor against the Pertronix fitment list before ordering.
What electrical system does the LU-149 require?
It is built for a 12 volt negative ground system. Confirm your vehicle matches this voltage and ground polarity, because Ignitor kits are voltage and ground specific.
Does the LU-149 need any maintenance or a special coil?
No routine maintenance is required once installed, and there are no points to re-gap. It works with the vehicle's existing coil or a compatible Pertronix Flame-Thrower coil that matches the system voltage.
