Lighting assemblies changed significantly between the chrome-bumper and rubber-bumper eras, and there were further revisions within each period. The front of a chrome-bumper Midget uses separate side light and indicator assemblies mounted on the front wings or front panel, while the rubber-bumper 1500 integrates these functions into combined units housed within the bumper moulding. The rear lamp clusters also differ between the two body styles, the squared-off rear lamps introduced with the GAN5 facelift in late 1969 replaced the earlier rounded type, with different lens patterns, gaskets, and bulb holders across the production run.
Headlamps
The original headlamp units are sealed beam items available with or without an integral pilot light, depending on the production date. The headlamp bowl is available in both metal and plastic versions. Headlamp rims, gaskets, and inner bowls are stocked individually for cars where the headlamp surround has corroded or been damaged but the sealed beam unit itself remains serviceable.
Halogen Headlamp Conversion
Halogen headlamp conversion kits fit within the existing headlamp bowls and use the same electrical connections as the original sealed beam units, making the upgrade straightforward. The improvement in light output is substantial, on unlit country roads, where most Midgets spend their evening driving, the difference between sealed beam and halogen is the difference between adequate visibility and genuine confidence. Conversion kits are available for RHD and LHD, with and without pilot light, so the correct version must be matched to the car's original specification. A high-output halogen bulb is also available for owners wanting maximum light output from the conversion.
Indicators and Side Lights
Front indicator and side light assemblies differ between the chrome-bumper and rubber-bumper body styles, and changed within the chrome-bumper era. Indicator stalks also changed across production, early cars used a stalk without horn function, while later cars integrated the horn push into the indicator stalk. The indicator cancel stud, trip mechanism, and associated components are available individually.
Rear Lamps
Rear lamp clusters differ between the pre-1970, post-1970 chrome-bumper, and rubber-bumper body styles. Lenses, gaskets, bulb holders, and complete assemblies are available for all three types. The lens pattern and gasket profile differ between types and are not interchangeable.
Number Plate Lamps
Number plate lamp assemblies changed at least three times during production, with different lamp bodies, lenses, covers, and gaskets at each change point. The correct type is determined by the production date.
Later lamps were available in both chrome and black finish. Plinths, gaskets, and packing pieces are stocked individually for cars where the lamp itself is serviceable but the mounting components have corroded.
Interior Lighting
A courtesy light switch in the door jamb operates the interior light on cars so equipped, not all production periods included a courtesy light. A boot light switch is also listed, though availability of the original item is limited. Bulbs for all interior and exterior lamp positions are stocked.
LED Bulbs
LED bulbs are available for all lamp positions, side lights, indicators, tail lights, number plate, and interior courtesy light, offering improved brightness and significantly reduced current draw. When fitting LED indicator bulbs, a LED-compatible flasher unit is required to maintain the correct flash rate, as the standard bi-metallic thermal flasher interprets the reduced current draw of LEDs as a blown bulb and doubles the flash speed. A spare bulb kit containing all standard filament bulbs is available for owners carrying a roadside emergency kit.
