These T10 COB LED bulbs use a high-power chipset and a full 180-degree illumination angle to spread light more evenly through side markers, license plate lamps, reading lights, door lights, trunk lights, and roof lights. The silicone body absorbs vibration and dissipates heat, extending the bulb's usable life in demanding automotive environments. Each bulb runs on standard 12V DC, matching the typical output voltage of a car's electrical system, so no extra converters or modifications are needed. Available in a range of eight colours, these bulbs are supplied in a pack of ten, making them suitable for multiple applications in one vehicle or across several vehicles.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"T10 COB LED bulb 21.5mm length 9.5mm diameter silicone body 12V DC automotive\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1083\/2025-10-02\/original-image\/1736631939026259968.webp\"\u003e\u003c\/div\u003e\u003cp\u003eBuilt around a COB (Chip-on-Board) LED array, these bulbs deliver consistent, bright light without the dark spots common with older SMD designs.
