PhinlionSuper Bright 3014 72-SMD 3056 3156 3057 3157 4057 4157 Amber Yellow LED Light Bulbs for Turn Signal Blinker Lights Lamps

My turn signals now blink at a faster rate. Not the end of the world but would prefer if they would blink at a slower rate.

The colour is amber and they are fairly bright. I would buy them again.

These are great LED lamps and the cost is reasonable. But... Like many LED's they don't match the load of original lamps so turn signals flash rapidly. Will each require a load resistor or aftermarket flasher to work properly.

I had a couple of problems with this purchase. First I received an empty envelope with no bulb inside. I made a claim with Amazon and they reordered the product at no additional cost. But they expected me to return the first purchase. So I guess I was supposed to send back the empty envelope. But I had already thrown it away. So ultimately I was charged for both the 1st and 2nd items, even though I only received one. Second, because this is an LED which draws very little power, my truck doesn’t recognize that the bulb is plugged in. The bulb works perfectly fine. But it still blinks very fast, mistakenly thinking the bulb is out. Apparently, there is something you can get to correct this. But why is that not part of this bulb? Would not recommend.

The 3757A/NA bulb is designed with a small change in the side tab to prevent installation of a non-amber 3157, so most aftermarket 3157 LEDs won't fit in a 3757 socket. These do. Their tabs are JUST narrow enough to clear the socket openings, and they fit solidly in my 2020 Explorer Limited's rear turn signal sockets.I used FORSCAN to stop the instrument cluster fast-flash, which is the only hyperflash you'll see on newer Fords...the exterior lights still flash normally, so you may not even feel the need to fix it. But if you have FORSCAN, you can change the BCM code 726-44-02 (2020 Explorer only) so that the second digit of the code content (x*xx xxxx xx) is a ZERO. Other Fords have different codes...don't change these unless you're sure you have the right codes for your car/truck.Also, Ford uses PWM to pulse the rear turn signals in low-light conditions, so that they're slightly less blinding. Some other LEDs don't like PWM on the on-cycle, where you'll see rapid/violent flickering instead of solid-on. These bulbs are solid-on.As for the brightness, they're just a bit brighter than the standard incandescent bulbs, and a deeper amber color than some of the other LEDs I've seen. I'd say 25-33% brighter than stock.I'm not sure how warm they'd get with the parking-lamp (low) connection running continuously, since my rear turn signals are flash-only and I didn't have a chance to test that (the 2020 Explorer's front turn signals are LED).VERY happy with these bulbs so far. The instant on-off and the higher brightness are big improvements.PROS:- solid-on, even with pulsed (PWM) input- deep amber color, really noticeably better than some other yellow/amber LEDs- slightly brighter than OEM bulbs, but only by about 25-33%, I didn't have time to grab a side-by-side video- fits 3757 sockets with no modifications- top-mounted LEDs light up nicely for direct rear-facing illumination- LEDs don't seem overdriven, so no parts of the "bulb" get even warm in turn-signal-only use- no polarity issuesCONS:- they'll probably hyperflash in most installations, but luckily, most Fords can be fixed without resistors- they're not insanely bright- they're slightly tall, so they may not fit and/or they may change the beam spreadNone of these cons were deal-breakers for me. I'll update if something changes.
