【Set of 2 white amber 1157 LED bulbs】All in one error free 1157 led bulbs, will not hyper flash, no extra resistors need. Have polarity. For a few sensitive vehicles (Chrysler, Chevr-olet, GMC, RAM and Volkswagen) the built-in load resistor may be not able to solve the hyper flash, and extra load resistors maybe required.
【Super Bright white amber 1157 led bulb canbus】42pcs SMD led chips(27 Amber LED + 15 White LED), 12V working voltage.360 degree beam angle, 300% brighter than halogens.
【Dual Function 1157 led bulbs built in resistor】 Light up xenon white for side light; Light up amber yellow for turn signal lights. The turn signal flashes "amber-off-amber-off," instead of "amber-white-amber-white," which makes it easier to see. Please note: the amber and white light can't be light up at the same time.
【30,000+ Hours Lifespan】 Full aluminum housing and built-in Constant Current IC Driver for fast heat diffusion and more stable performance. No digital and VHF radio signal interference. These 1157 LED bulb switchback last 30,000+ hours compared to only 2000 hours for incandescent bulbs.
