Deep, vivid blue — the most iconic colour in the fairground lighting palette. This blue E14 cabochon cap and base set is the two-part plastic housing that forms each individual light point on a fairground display, light-up letter, illuminated sign, or amusement ride border. The blue domed cap clips over the assembled base and bulb, casting a deep, vivid blue glow — the instantly recognisable colour found on waltzers, ghost trains, carousel borders, and dodgem canopies at fairgrounds and carnivals across the UK. Sold as one matched pair — one blue cap and one blue base — ready to combine with an E14 LED bulb for a light point. These are the same components used in our own professional letter fleet, deployed at weddings, venue installations and corporate events across the UK — so we know exactly what they're capable of and how they hold up under repeated use. Specifications: Fitting: E14 (small Edison screw, 14mm thread diameter) Cap colour: Blue Base colour: Blue Cap diameter: 60mm Assembly height: 63mm Compatible voltage: 24V DC or 240V AC E14 bulbs Material: Polycarbonate Sold as: 1 blue cap + 1 blue E14 base (bulb not included) Colour output: Through a warm white E14 LED bulb (2700K–3000K), the blue cap and base set produces a rich, deep blue glow with a slightly warm tone. Through a cool white bulb (4000K–6500K), the output becomes a purer, more vivid electric blue — crisper and more saturated. For maximum colour intensity, cool white is the better pairing. Cool white bulbs are available to order with approximately 2 weeks lead time — contact us before placing your order. What it's used for: Light-up letter and number builds for weddings, parties, corporate events, and venue installations; fairground-style marquee signage and illuminated shopfronts; amusement park rides and fairground attractions — including waltzers, carousels, ghost trains, dodgem arenas, big wheels, and ride canopy fascias; travelling fair equipment; film, TV and theatre set dressing; retail window displays and exhibition stands; hospitality venue feature lighting. If you see the classic domed fairground bulb anywhere — in a production, at a venue, on a ride — this cap and base set is the housing creating that effect. No minimum order.

Compatibility: E14 fitting only — not compatible with E10 (40mm) fittings. Requires a separately purchased E14 LED bulb to function. Compatible with 24V DC and 240V AC E14 bulbs. See our Full Light Set (cap + base + bulb) for the complete assembly in one product. How can it be used? To create one completely working light point, you will need the following components working together: E14 Cabochon Base — the conic housing that sits in your letter panel or ride fascia E14 Cabochon Cap — the domed cover that clips over the base and bulb E14 LED Bulb — the light source that screws into the base via the Edison screw thread Nut and nut holder — used to secure the base firmly into your panel or fascia, ensuring the unit stays fixed in place during use, transport, and repeated setup All four components are required for a fully functional, secure light point. The cap and base set covers the first two — see our E14 LED bulbs to add the light source, and ensure you have the correct nut and nut holder for your panel thickness before installing.
