The original Lotus Elan M100 headlight pod control module (A100M6027F) is no longer available from Lotus or GM. Over time these original units commonly fail due to overheating, failed relays, cracked solder joints resulting in unreliable stall detection and MOSFET burnouts.
This Pod Lift module is a modern, direct drop-in replacement designed to solve those problems and restore reliable headlight pod operation — including fixing a known limitation of the original GM module: genuine LED headlamp compatibility. The original module senses bulb current to decide when the lights are truly on, which fails with LED bulbs (pods raise but won't lower) unless a wire-wound resistor is fitted to imitate a halogen bulb. This replacement reads the switch state directly instead, so it works identically with halogen, LED, or no bulb fitted at all.
Key features
Position memory — remembers pod position even after battery disconnect
Independent motor stall detection
Obstruction safety cutoff
Genuine LED headlamp compatibility — no dummy resistor required
Ultra-low idle current — ideal for long-term storage
Conformal coated for protection against moisture, condensation and vibration
Direct drop-in fit — no wiring modifications required
Custom 3D-printed carbon black PLA-CF enclosure
Hand-built and fully tested in the UK by Digconn Systems
Replaces
Lotus part number: A100M6027F
GM part number: GM16509097
Also sold as: GM16521278 (later superseding GM part number, same module)
Confirmed compatibility
Lotus Elan M100 (1989–1995)
Also expected to fit (pending confirmation)
Buick Reatta (1990–1992)
Oldsmobile Toronado / Trofeo (1990–1992)
Pontiac Firebird / Trans Am (1990–2002)
Pontiac Sunbird (1990–1994)
Important note The Lotus Elan M100 is the only vehicle fully tested and confirmed. The other models above share the same later-generation GM module family and are expected to be compatible, but have not yet been independently verified.
