Each bulb packs 40 high-performance SMD 1210 LEDs to deliver a bright, brilliant red illumination that improves visibility and safety on the road. Built for 12V systems, they provide a clear, consistent glow that helps other drivers notice braking and turning intentions sooner, reducing the risk of rear-end collisions in tricky lighting conditions.\u003c\/p\u003e \u003cp\u003eWith a compact 45mm length and 21mm width, these bulbs fit standard T20 (7440) sockets and are designed for plug-and-play installation. No wiring or complicated modifications required—simply remove the old bulb and replace it with the new LED version. The dual-function design suits a range of applications from tail and brake lights to turn signals and DRL, giving your vehicle a cohesive, modern lighting finish.\u003c\/p\u003e \u003cp\u003eDespite their universal compatibility, always verify that the bulb type matches your vehicle’s housing before purchase. The 12V DC bulbs are rated at 6W each and produce about 450 lumens per bulb, ensuring strong visibility without excessive power draw. If the LED light does not work immediately after installation, try reversing the polarity. Depending on your vehicle’s electrical system, you may also need to install a load resistor to prevent hyper-flash or error codes in some European or modern models.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrighter, more reliable red illumination for tail, brake, and turn signals improves safety and visibility in daytime and night driving.\u003c\/li\u003e\n\u003cli\u003eEasy, tool-free replacement with a standard OEM socket—no wiring or modifications required.\u003c\/li\u003e\n\u003cli\u003eLow power consumption with a longer service life compared to traditional halogen bulbs, reducing maintenance and replacement frequency.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBulb type\/compatibility: 580\/7443 W21\/5W dual-filament and 7440 variants; base T20 (7440)\u003c\/li\u003e\n\u003cli\u003eLED quantity: 40 SMD 1210 LEDs per bulb\u003c\/li\u003e\n\u003cli\u003eLight color: Brilliant Red\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V DC\u003c\/li\u003e\n\u003cli\u003ePower: 6W per bulb (12W for a pair)\u003c\/li\u003e\n\u003cli\u003eLumens: ~450 lm per bulb\u003c\/li\u003e\n\u003cli\u003eDimensions: 45mm (length) x 21mm (width)\u003c\/li\u003e\n\u003cli\u003eWeight: 23 g per bulb\u003c\/li\u003e\n\u003cli\u003eApplications: Turn signal light, tail light, sidelight\/indicator, parking light, DRL, and reverse light\u003c\/li\u003e\n\u003cli\u003eOrigin: Mainland China\u003c\/li\u003e\n\u003cli\u003eTechnology: LED\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2x RED 582 7440, 580 7443, 992 LED 40 SMD Sidelight Reverse Light Lamps\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings\/Reminders\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePolarity: If the LED light does not illuminate after installation, reverse the polarity.\u003c\/li\u003e\n\u003cli\u003eSome vehicle electrical systems may require a Load Resistor to prevent hyper-flash, error codes, or malfunction messages when using LED bulbs for turn signals or brake lights.\u003c\/li\u003e\n\u003cli\u003eDue to size differences from stock bulbs, confirm that these LEDs fit your vehicle’s light housing and socket before purchasing.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eAt intercyprus.com since 2002 — trusted for quality and reliability.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"Red","offer_id":52302332559702,"sku":"1005007655286793-Red","price":21.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Sd67f9e5fbc844418a537b74608926bc8j.webp?v=1768081970","url":"https:\/\/www.intercyprus.com\/products\/angrong-2x-red-580-7443-w21-5w-582-bulb-smd-40-led-side-indicator-tail-brake-stop-light","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
