They were fitted as standard to very early cars. The Light Panels will fit straight into the rear side pockets of Mk1 and Mk2 cars: Screws onto the ashtray body panel. Some even have the fixing holes already there. Light Panels will fit straight into the rear side pockets of later cars BUT the inertia reel seat belt fixings have to be lowered and the ashtray panel fitted (These are included in the auction). The seat belt can come up through the ashtray slot. The ashtray panels can be fixed just to the pockets rather than welded to the door post if you want to avoid damaging paintwork. An aperture needs to be cut in the pocket cardboard lining and the vinyl tucked through. Lenses were not fitted to these lights. If you want a template for cutting the pocket lining I'll include it with no extra charge!
