Alla Lighting T25 3157 LED Switchback Bulbs for Turn Signal Lights

The listing showcases a set of two super extremely bright 3157/3457/4157NA LED switchback dual-color amber-white high-power 2835 28-SMD LED bulbs, specially designed to replace the original bulb. These bulbs have a dual function, serving as both the front turn signal and the parking or daytime running light (DRL) on the same bulb.

Specifications: 1) Package: Includes two pieces of extremely super bright 3157 LED switchback bulbs. 2) LED Chips: 21 pieces of high-power 3035 SMD per LED bulb. 3) Cross Reference: 3157 3157A 3057 3155 3157NA 3357 3457 3457A 4057 4114 4157 4157NA, etc. 4) Functionality: Lights up white for parking lights or daytime running lights, and lights up amber-off-amber-off for turn signal lights, making them more noticeable compared to constant amber. 5) Warranty: One-year guaranteed manufacturer's quality. 6) Note: Due to the lower current draw of LED bulbs, your car may require a load resistor to avoid hyper-flashing or malfunction.

These bulbs are compatible with both standard and CK sockets. The LED type is 21 pieces of high-power and high-illumination 3035 LED chips per bulb.

The dual-color feature includes 6000K xenon white and amber yellow. The white light is used for parking lights or daytime running lights (DRL), while the amber-off-amber-off pattern is used for turn signal lights, making them more noticeable.

The cross-reference numbers include 3047, 3047LL, 3047K, 3057A, 3057ALL, 3057, 3057ST, 3057K, 3057KX, 3057X, 3057KLCP, 3057LL, 3155, 3155LL, 3157A, 3157AK, 3157, 3157K, 3157X, 3157LL, 3157ST, 3157KX, 3157NA, 3157NALL, 3157NAK, 3357A, 3357ALL, 3357, 3357LL, 3357K, 3454NA, 3457A, 3457ALL, 3457AK, 3457, 3457K, 3457NA, 3457NAK, 3757A, 3757AK, 3757ALL, 4057, 4057LL, 4057K, 4114, 4114LL, 4114K, 4157, 4157LL, 4157K, 4157NA, 4157NAK, 5702A, 5702AK, 5702AK, 3157-SCK, 3157-SRCK, 3157-SACK, etc.

It requires a 50W 6-ohm load resistor, and the LED switchback only works effectively if the original bulb has dual functionality: front turn signal and parking/DRL on the same bulb.

The dimensions of the bulbs are 0.70 inches in diameter and 2.50 inches in length. The product comes with a 1-year hassle-free warranty. It operates on a working voltage of 12V to 18V DC and is energy-saving, with low temperature, low power consumption, and a longer lifespan of up to 50,000 hours, making it a great value in the market.
