Like extending a handshake of light with your turn signal
by Raspen (5 out of 5 stars)

Picture Descriptions:
1 & 2) Comparing OEM bulb to new bulb in the dark and light (LED on the right if that wasn't insanely obvious :D)
3) Both bulbs installed, showing the difference between the switchback colors (very crisp)
4) Just showing that the amber signal turns fully off between flashes, making it even more obvious

This is by no means my first pair of replacement LED bulbs on a vehicle, but it is my first switchback LEDs, and as such I didn't fully know what to expect. I typically purchase JDM ASTAR LEDs because I've been impressed by their quality, lifespan, and customer service in the past. These bulbs are no exception to their great reputation and if you're on the fence about trying out switchbacks then just check out my pictures -- the difference between the OEM bulbs is great enough, but the crisp difference between the white DRL and the amber turn signal just feels like I'm reaching out to anyone in front of my vehicle and yelling "I'M DEFINITELY TURNING".

A couple things to note when purchasing these bulbs:
1) They are almost a full inch longer than the OEM turn signal bulbs -- I really don't see any modern headlights having issue with the bulbs being too long, but it's worth noting.
2) You WILL need an resistor installed inline with these bulbs if you're replacing an incandescent bulb.
3) Take pictures!! I'm sure tons of people would love to see what your rig looks like after installing these bad boys, especially for reference if they have the same car.

literally if you have wrap around headlight fixtures like these mustangs
by Tacarius Malik Wills (5 out of 5 stars)
April 12, 2017

I purchased these switchbacks to replace my dim and I mean very dim yellow halogen turn signals that couldn't be seen in daylight and can only be seen when it's basically dark outside. They are VERY BRIGHT, literally if you have wrap around headlight fixtures like these mustangs, it shines light all on the side of interstate walls, and even points light slightly behind you at a slight angle. If you are on a 3 lane road or any road they lights up the two lanes beside you. The 50 W 6 Ohm resistor is indeed needed to prevent hyper flashing, if not (I haven tested without it) it may not function properly and may not even return to white once turn signal is deactivated. For most 3 wire turn signals, the only thing you lose is the flash of the light when you press the lock button twice when locking your vehicle, this is due to the resistor not the bulb. The resistor resists that split second pulse of electricity that comes from the panic/press lock twice to set alarm vehicle. There has to be an electric current flow of a 1.5 seconds or more in order for that resistor to allow the current to flow to the other side of the wire. For the 3 wire you splice the resistors on wire terminals "Brake/turn signal and Ground", do not touch running lamp wire. When you make the decision to switch (get it switch because these are switchbacks- inside joke) you will have to continue with these types of lights. If I could give them 6 stars I would because they take just about any car especially a 15.5 year old one like mine and turn (get it, turn because these are turn signal lights) your car into that "Audi, Mercedes, new car" running light look.

2006 Dodge Ram LED Switchbacks
by Jarrette (5 out of 5 stars)
April 30, 2016

I bought these for my 2006 Dodge Ram 1500 and were very pleased with them. A little note to people looking into these kind of bulbs, there are two different types of these lights...(im sorry, the different names for them have alluded my brain at the present time)

There is the kind of switchback led's that alternate between white and amber when the turn signal is on-then back to white.

And the kind that when you use your turn signal they only show amber, then when you take your turn signal off-they illuminate back to white (most new cars have these kinds...Mustangs, Lexus's, etc...) THESE BULBS ARE THOSE KIND. I have had these running on my truck for a little over a week now with no problems; but only time will tell the durability of these bulbs. They definitely turn heads though.

Great customer service and fast replacement
by Yia Moua (5 out of 5 stars)
December 11, 2016

I received mine on 11/22. Today, one of them went out on me. I checked by replacing it with an old OEM bulb and the old bulb works so it's not the fuse. I also checked the fuse to make sure. The lights are bright and good. Just that I can't believe it already went out on me. Can someone from JDM Astar get back to me for a replacement?

Update 12/13/2016: JDM contacted me via email and asked me to use the swap the bad one on the other side. I tried and still does not work so they offered to send me a replacement bulb. Will update again once I have received them.

Update 12/15/2016: JDM contacted me on Tuesday 12/13 that they will send me a replacement. I received my replacement today. That's two days!!!!! I am impressed. I installed the replacement I received and it works. Hopefully it lasts a long time this time around. Great customer service and fast shipment. I am giving it 5 stars now.

Worth the money
by Noel S. (5 out of 5 stars)
March 7, 2017

I have these on my 2000 GMC Yukon XL SLT (with Denali projector headlights), and I love them.

The white light from these lights are almost as bright as my 35w HID low beams in the projectors.

Like another reviewer said, the parking light turn off when you turn the turn signal on, and has a small delay before they turn back on. It had a nicer look to me than the lights that switch between white and yellow.

In the photos I've attached, the brightest one (first photo) is the fogs (stock halogen bulbs), switchbacks and 35w HID headlights all on. The second (slightly dimmer), is just the HIDs and switchbacks, the 3rd photo is just the switchbacks by themselves. The last photo is the head-on shot of the truck. Keep in mind these were taken on a foggy, wet night, so the pavement is wet.

I've only have had these for a month, but so far they are working great.

Switchbacks on steriods!
by Michael (5 out of 5 stars)
December 22, 2015

I had some generic switchbacks with the white, orange, white, orange, flash pattern. And decided I needed something a bit brighter. A bit brighter does not describe these. These are some leds on steroids.... Not only is the white almost similar to an hid, but the orange is bright as f*** too!!! The straight orange on orange off pattern is much much better too. Makes my car look more classier lol. Love them!

These Dual White/Amber #3157 LED Bulbs Are Really GREAT!
by R H F (5 out of 5 stars)
November 6, 2016

These Dual White/Amber #3157 LED Bulbs are really GREAT! Adds a very Bright Xenon-White(6500K) @ 1500Lm DRL to a vehicle that doesn't have DRLs. Plus the Amber/Yellow LEDs are also ~1200Lm; that's about 3X lumens of a standard 3157 Bulb (~400Lm). Normal operation White Daytime Running Light (DTRL) function. Turn Signal Amber/Yellow Flashing On/Lit & Off/Dark; which produces a bright high-contrast turn indicator. So, now just turn on the Parking Lights during the day and you now have DRLs and Side-Markers; no headlights required for added safety.

More good news in the construction of these 3157 LED Bulbs is the wire contacts; they are thicker/flattened wires that give very good strong contact with the plug's contacts. The problem [IMHO] with most automotive LED Bulbs is the wire contacts; the are to skinny/flimsy and do not fully make a strong contact; thus causing the bulb to loose contact an become intermittent and appear to fail. These skinny/flimsy wires use for contacts in these other LED Bulbs [IMHO] are a result of single focus design engineering. The LED Bulbs draw less current so the contact wires can be smaller: NOT! The prime purpose of the Bulb's Contact Wires is to MAKE CONTACT; and JDM aStar did the job right with these Switch-Back White/Yellow #3157 LED Bulbs.

3 out of 5
by Kory (3 out of 5 stars)
February 26, 2019

So I wanted to wait and really experience these lights before I wrote a review. So I score it a 3 because they only hit 3 out of 5 marks. 1, they fit perfectly. No problems replacing and mounting this bulbs. 2, they are BRIGHT and look great on the car. The color blends great with my LED headlights. 3, I like the way they switch from a solid white to blinking amber and then back.

The issues I had are functionality. 1, canbus error. They register a canbus error so I get the flash blink as if a bulb is out which grows to be annoying. 2, delay in illuminating. There is a 1-2 sec delay before the lights turn on so when I lock the doors the lights don't flash

If you can get over the flaws these look great. I may wait for a few more months before looking for some that address the canbus error

The parking lights are a nice crisp white at night
by Huy Ly (5 out of 5 stars)

I have a 2009 Toyota Corolla and these replaced the factory turn signal/parking light in the front of the car. The parking lights are a nice crisp white at night. I would even dare to to say they light up the sides of the road quite well. And the amber turn signal light up the area pretty well!!! I paired them with the JDM ASTAR super white led bulbs for the rear of the corolla as well. Since I had 4 led bulbs in both the front and rear, I bought 4 of the 50 Ohmm resistors and wired them in parallel in the rear of the car. I'm sure had I remember physics I could have gotten just two 25 ohmn resistors or something.

I bought theses in December of 2016 and installed them right away when they got here. Here I am writing a review for them in June 2017. The switch back led in the front and the whites in the rear have held up pretty well. Unfortunately the front right one now seems to work sometimes. The problem started almost 2 weeks ago. The white led would not turn on but the amber would work fine. I stuck the oem bulb back in and it worked fine. I put the led back in and it would have the same problem. I even swapped the leds to different sides and it had the same problem. JDM ASTAR please help!!! I love the switch backs but my headlights look wonky at night now.

Edit July 11 2017

I contacted Jdm Astar and I received a prompt reply from the warranty department. I sent in the old one and received a new one within 1 and a half weeks. They very professional!

Still going after three years
by Anthony Campion (5 out of 5 stars)

Still going after three years.

Now I love these bulbs. The switchback LEDs are pretty great I spent probably a considerable amount of time looking for a decent bulb to replace the halogen one and fortunately I found this one these are the ones who led me to buy more of their products because that's how good they are the White part of the LED is pretty bright to a point where depending on your application you probably won't need to use your headlights and some lower lip areas or if you're just trying out to blind people through a neighborhood at night that Amber is pretty bright working reflect office signs pretty decent the switch back between Amber and White is probably a second and a half for delay but it's pretty decent I just highly recommend this company with my truck I have LED everything upfront it's all white but when I need to turn signal this thing doesn't get dim it's still packing a punch
