Why do you need LED turn signal bulbs with a built-in resistor function?

When you want to upgrade your car's turn signals from yellowed, dim halogen bulbs to brighter regular LED turn signal light bulbs, you may notice that they are blinking much faster than your previous light bulbs. And that low voltage LED turn signals will trip the onboard vehicle computer system (CANBUS) and cause error lights to pop up on your gauge cluster display. You can choose to add an external resistor or relay, but you need to consider the installation and placement of the decoders, which can make things tricky.

Fortunately, AUXITO can provide you with a range of LED turn signal light bulbs, and feature innovative technology with a built-in resistor function, preventing hyper flash and error codes.

TOP ADVANTAGES OF 3157 Turn signal lights

High brightness

AUXITO 3157 led turn signal bulbs use 24 pcs 3020 LED chips for 360° illumination. 300% brighter than halogen bulbs. The light source is closer to the halogen light bulb, a good beam pattern.

Good cooling system

The whole aviation aluminum lamp body and hollow-out body design give the LED turn signal lights efficient heat dissipation. To ensure a secure temperature range and 40,000 hours of life span.

Easy to install

Non-polarity, Compatible with US standard and CK type, directly fit for 3157, 3156, 3457, 3056, 3057, and 4156 sockets. Sit tight in the socket, without loose connection. Mini-size design, with no extra load resistor, fit the turn signal light housing perfectly.

Energy saving

No blinding to other drivers. No waste of energy and no additional heat. Please note that the 7440/7443 led bulb only can be used for turn signal lights.

Compatible with 90% of vehicles’ system

The 3157 led turn signal light bulb is 25W per bulb, amber-yellow light. For some sensitive vehicles, load resistors (decoders) are needed.

Warm Tips

Please double-check owner's manual or original bulb size to confirm before placing an order.

Please follow the steps to check if the size of the turn signal bulb will fit your car.

1. Check your owner’s manual or search automotive bulb fitment online to find the right turn signal light bulb size for your vehicle.

2. Take off the original turn signal light bulbs on your car to double-check the size.
