Starlight Headliner Fiber Breakage

MinorInterior & Trim

The iconic Starlight headliner uses fibre-optic strands to create a starry sky effect. Over time, individual fibres can break or go dark, creating visible gaps in the star pattern. Complete headliner replacement is the only true fix.

Est. Repair Cost: £3,000–£8,000
Warning Signs:

Dark spots or gaps in the starlight pattern, Individual fibres no longer illuminating, Uneven star brightness across the headliner

What to Inspect:
  • Inspect the headliner with the stars illuminated in a dark environment
  • Check for any visible fibre breakage or dark patches
  • Ask if any fibre repairs have been carried out
