Registration-Lamp Camera Insert

Transparent registration-lamp insert with a mount for the compact CVBS/AHD camera commonly supplied with aftermarket head units. The creator explicitly states W203 and W209 fitment and recommends transparent PCTG or PETG, aligned 100% infill, no top or bottom layers and ironing. Compare the lamp opening and camera body, seal cable entries, preserve required plate illumination and verify the insert cannot detach or leak into the boot lid.
