Pair of 2, for Standard Socket, 3157 3057 3357 4157 Turn Signal White Yellow Amber Switchback Led Light Bulbs 22 SMD with Projector, Not CK

Vouke #ad - Load resistorfew vehicles may have hyper flashing because led draws much less power and lasts longer than stock incandescent lighting. Dual color, unlike the traditional dim Amber color, our high powered Amber chips emit very bright golden light. Yellow leds light up for front turn signal lights.

The turn signal lights flashes in "Yellow-off-Yellow-off" mode, which makes it easier to see. Our bulbs come with Standard Base, NOT CK Type. Xenon white leds light up for parking lights or daytime running lights. This happens because your new LED bulbs draw such little power that your turn signal relay sees the bulbs as being out. If your car has flashing, pls add 50W 6-Ohm load resistors or flasher relay. Applicationdual function switchbacks. Although the reduced draw of LED has advantages, replacement of turn signal bulbs with LED may cause hyperflashing.

Fitmentstandard 3157, cross reference: 3047 3057 3357 3457 4057 4114 4157 3057A 3157A etc. Tips before purchasethis only replace dual-function stock lights that have both the parking/DRL light and front turn signal function in one bulb. Gold/white 3157 switchback used as Front Turn Signal Light / Parking/DRL lights. Featurepair of 2 22-pieces high power 5730-chipsets. So your stock bulb must work in 2 functions, otherwise, this will only work in one color or not lighting up normally.
