【Tips Before Purchase】This only replace dual-function stock lights that have both the parking/DRL light and front turn signal function in one bulb. So your stock bulb must work in 2 functions, otherwise, this will only work in one color or not lighting up normally. Our bulbs come with Standard Base, NOT CK Type. | 【Feature】(Pair of 2) 22-pieces high power 5730-chipsets. Dual color, unlike the traditional dim Amber color, our high powered Amber chips emit very bright golden light. Gold/White 3157 switchback used as Front Turn Signal Light / Parking/DRL lights. | 【Application】Dual Function Switchbacks. Xenon white leds light up for parking lights or daytime running lights. 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. | 【Fitment】Standard 3157, Cross Reference: 3047 3057 3357 3457 4057 4114 4157 3057A 3157A etc. | 【Load Resistor】Few vehicles may have hyper flashing because LED draws much less power and lasts longer than stock incandescent lighting. Although the reduced draw of LED has advantages, replacement of turn signal bulbs with LED may cause hyperflashing. 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.
