Our kit contains 50 x 1.5 metre clear sheathed fibre tails each containing 3x 0.75mm cracked polymer fibres, illuminated by a MiniLED550 light source with colour-sparkle wheel. This is our "standard" kit, but we're very happy to make up custom harnesses to suit your own needs or preferences. The difference in price will simply reflect the amount of fibre required to make up your specific harness.
