Product Details
✓CANBUS ERROR FREE: Super compatible for 99% Vehicles. No hyper flash, no errors, no warning. With built-in CANBUS system, these 7443 dual color bulbs can directly alleviate decoding problems without trouble to prepare external resistors. Auxbeam offers 1-year warranty. NOTE: NOT fit Grand Cherokee, 2016-2017 RAV4, 2014-2021Tundra, etc. For sensitive models such as Silverado and 2014-2018 RAM 1500, extra resistors are needed or get from us.
✓600% EXTREMELY BRIGHT: Sequencing 36Pcs Upgraded high brightness 3030SMD chips precisely around each 7443 led bulb, 28W per bulb, High Power and 600% brighter, providing 6500K Cool White light or 3500K Amber Yellow light. Instant-on response without warm-up time. More noticable when turning, guard your driving safety.
✓DUAL COLOR FUNCTION: This 7443 switchback led bulb with resistor lights up cool white for parking lights or daytime running lights (DRL) but amber yellow for turn signal lights. Unlike most turn signals flashing "amber-white-amber-white" on the market, the Auxbeam 7443 turn signals flash "amber-off-amber-off", making it easier to see from a distance.
✓COOLING SYSTEM REALLY MATTERS: IP68 waterproof. The built-in stable current IC driver avoids digital or VHF radio signal interference. The latest 4-layer cooling system - 12,000RPM silent fan + Copper cooling ring + 16Pcs heat sinks + 6063 aviation aluminum lamp body directly doubles heat dissipation, ensuring longer lifespan up to 60,000 hours.
✓360°FULL CLEAR BEAM: Each 7444 led bulb provides 360° full illumination without dark spot or shadow. Compatible for standard sockets rather than CK sockets. Fit socket 7443, 7443A, 7443LL, 7443NA, 7444, 7444NA, 7444LL, W21W, T20, etc. No polarity, no drilling, no wiring, no damage, just Plug and Play.
