OXILAM 7440 Amber LED Bulbs – 4000LM Turn Signal with CANBUS Error-Free (2-Pack)

Bright amber signal lighting for your vehicle

OXILAM 7440 LED bulbs deliver a warm amber glow at 2200K, designed to replace standard turn signals. Each bulb packs 26 x 3020 SMD LEDs, producing up to 4000 lumens per pair, which stands out next to conventional bulbs and helps signaling be more noticeable to other drivers. The bulbs run on a wide DC 12-24V range with a ~21W per-bulb draw, balancing strong illumination with efficiency. This combination of brightness, color, and compatibility is aimed at drivers who want a crisp signal without frequent maintenance.

Key features at a glance

• Ultra-bright amber light: 4000LM per pack, 2200K glow for clear signaling
• Wide voltage range: DC 12-24V, suitable for most 12V and 24V systems
• Long-life design: aircraft-grade aluminum body with enhanced heat dissipation for up to 60,000 hours
• Socket compatibility: fits 7440, T20, 7440NA, 7441, W21W, WY21W, and related sockets

CANBUS compatibility and fine-tuning

The bulbs include a built-in CANBUS driver that has been fine-tuned to reduce common error codes and hyper-flashing on many vehicles. In some sensitive models (such as certain Jeep, Chrysler, Chevrolet, GMC, Dodge, RAM, and Volkswagen configurations) or when installing multiple pairs, a few users may still see flicker or warning lights. In those cases, external load resistors can help restore stable function. If you encounter an issue, we’re happy to discuss options including free load resistors.

Practical use and real-world scenarios

• City driving: a brighter amber signal helps other drivers react sooner at intersections and during lane changes
• Night-time visibility: a warm, crisp glow stands out in rain or fog without excessive glare
• Retrofit flexibility: designed to replace a range of common sockets with straightforward installation

Notes on compatibility and installation

Before purchasing, confirm your vehicle’s exact socket type and bulb part number. The 12-24V range covers most cars, trucks, and vans, but trim years and electrical configurations vary. Check your owner’s manual or use the vehicle guidance to avoid mismatches. If you’re unsure, contact support for a quick fit check.

Warranty and support considerations

These bulbs are built for durability and efficiency, but issues can arise in specific vehicle configurations. If needed, we offer support options such as load resistors to stabilize operation. This is a practical upgrade option to improve signaling reliability; results may vary by vehicle.
