My current halogen bulb size is 7443/7443NA/7444/7440/7440NA/W21W. Will these fit my vehicle as reverse lights?
Yes! These 7440 LED bulbs are designed for reverse, backup, and DRL applications. They deliver up to 500% more brightness than halogen bulbs, giving you a wider and clearer rear view when backing up at night.
Are these plug and play, or do I need a resistor?
For most vehicles, they are plug-and-play — no resistor or relay required. However, if your vehicle uses CANBUS or BCM systems, you may see a hyper flash warning. Adding a small load resistor or upgraded flasher relay can easily fix it.
Why did one bulb start flickering or stop working after a few months?
Flickering usually happens due to voltage fluctuation or socket contact looseness. Our bulbs have Smart Temperature Control and built-in surge protection, but if it happens, reach us immediately — our U.S. support team will send a replacement.
The Amazon fitment tool says “This Fit” or “Not Fit” — should I try it?
The fitment checker may not always be 100% accurate. Please double-check your owner’s manual or your current halogen bulb. If you’re unsure, just message us with your car’s make, model, and year, and our team will confirm fitment for you quickly.
What’s the lifespan of these LED bulbs, and how do I make them last longer?
Made of aviation-grade aluminum with a heat-dissipation design that ensures up to 30,000 hours of life. To extend lifespan, make sure sockets are clean and moisture-free during installation — 1-year replacement if any issue occurs.
