Review on 🔆 Partsam 2X 3157 3357 3457 Switchback LED Turn Signal Light Bulb - Dual Color White Amber 60 LEDs - Enhanced Brightness for Front Turn Signals by Juan Wilson

I love the reverse shift feature on these LED lights for my '98 Ford Explorer Sport. When they flash yellow and the turn signal goes out, the white LED lights up again after two to three seconds (at night when the daytime running lights are switched on). When the parking lights are off, they only flash amber like normal lights, with no reverse function. Yellow LEDs are no brighter than regular incandescent bulbs, but white LEDs are very bright. If I were to ask something, it would use brighter yellow LEDs to make them look like white LEDs. If your car is older than mine, don't forget to add a set of resistors to the turn signal wire, you will need one resistor for each LED bulb you are replacing. My car has two left and two right front turn signals, one above the headlight and one side marker light. I thought they were in parallel but no, each bulb requires an ASIN # B00VCSRI4A resistor sold right here at Revain. If a replacement turn signal module is about the same price as a resistor kit I would suggest buying one rather than adding a resistor to each turn signal bulb which is much easier to install. I didn't find the turn signal until I installed a resistor kit for my car.
