These are our 3rd Generation error free led turn signal light bulbs, come with all-in-one connection with better wiring decoder to prevent overheat, much safer compared to tradition load resistors.
Upgrade your vehicle's lighting with the Syneticusa 3157 Error Free Dual Color Type 2 Switchback DRL LED Turn Signal Light Bulbs. This pair of all-in-one combines daytime running lights (DRL) and turn signal functionality in a package. These 3157 LED turn signal bulbs boast high-power LED chips, delivering over 400% more brightness than standard halogen bulbs. This increase in illumination ensures your turn signals are highly visible, even in bright daylight, significantly enhancing safety on the road.
The dual-color switchback feature allows the bulbs to function as crisp white DRLs, adding a touch of modern style to your vehicle's appearance. When the turn signal is activated, the bulbs switch to a vibrant amber color, clearly signaling your intentions to other drivers. Say goodbye to annoying hyper flashing! These 3157 LED turn signal bulbs are designed to be error-free and hyper flash free, thanks to built-in resistors.
The non-polarity design further simplifies installation, making them compatible with both CK/SRCK and standard sockets. Constructed with a full aluminum housing, these LED turn signal light bulbs offer superior heat dissipation, contributing to a longer lifespan and reliable performance. The built-in constant current IC also plays a role in extending the bulb's life and ensuring low power consumption. Whether you're looking for brighter turn signals, stylish DRLs, or a combination of both, the Syneticusa 3157 LED Switchback Turn Signal Bulbs are the perfect solution.

I was curious if they would be bright or dim like most but these blew my expectations out of the water! These are not only great looking especially in Drl but very bright and enhanced the safety on the vehicle. 11/10 would highly recommend.

A little pricey, but these lights are very bright & work perfectly. Installed in a 2010 Silverado but the connectors wouldn't secure to the stock turn signal sockets. Replaced them with new 3157 sockets, soldered & shrink tubed the solder joints, & the LED Lights connect & stay in perfectly. Bright white running lights, & bright amber when the turn signals are on. The built in terminating resistors prevent hyper flash & the turn signals blink at a normal rate. I would recommend these to everybody wanting to upgrade their bulbs to the much brighter LED's.

Just installed these. They do the yellow flashing light thing on DRL and they actually spam the can bus. So much that my accessory protocol interface module isn't able to use the air conditioning blend door actuator. I had no heat this morning As a resul. do not buy these. Better off with a higher quality version. They looked nice at first, when parked the operated correctly, however as soon as I put my car in drive they went from white back to intermittent blinking amber. Working correctly with headlights on instead of drl, however the can bus problem is concerning.

Work absolutely perfectly, plug and play with my 2009 Chevy 1500. No hyper flash, and has a nice delay to the turn signals which make it look professional. White is nice and bright. Could almost be used as the headlights đ€Ł

Quedaron increĂble... No dan error de hiperflash la cual ya trae sus resistencias... El ponerlas por separado es muy difĂcil y es de peligro...estas solo se conecta directo a la base del foco y se coloca el nuevo y donde entra en la Mica y listo....blanco frĂo y al prender intermitentesse hacen ĂĄmbar...espero duren mucho

Physical Properties:Feels heavy in your hands. Connectors, wiring, and other hardware seems to be made of quality materials.LED was clean, and came in protective packaging.Brightness / Color QualitiesSUPER bright. Color matches the other LED bulbs' color (6007 I think).Switchback functions as intended, no hyperflash. The smaller bulbs shown in picture 2 had the hyperflash problem.The Amber color is in-line with most vehicle standard or OEM color, and is also very bright.Has a nice feature where when it switches back to the white light it takes approx. 1 second, made it feel like a quality product.They do NOT flicker like other LED's do.NOTICEABLY brighter than OEM. Added to headlight brightness because of the white light.Installation:A literal snap. This is a 2010 Ford F250 6.4 Powerstroke, their harness clips right into the factory harness and plug receptacle.The light fit in the OEM housing with a good fitment and nice rubber seal, I don't think it will fall out.Longevity:Can't speak to this yet, but it's tracking well enough already so I'll give it the benefit of the doubt. For $26 I really shouldn't complain.Overall: Nice product with good qualities on all aspects. Looks, feels, and performs well. Money well spent and would recommend to others.

No tienen error, no tienen hiper flash, al contar con su resistencia integrada no haces ningĂșn corte es plug&Play.No le pongo 5 estrellas porque a pesar de traer el protector en la resistencia si se calienta, debes tener cuidado de no ponerlos en plĂĄsticos.

I had these in my 2005 Tahoe for about 3 months now and to say the least am not overly impressed. First the good I love the two color style and the look of the white with the headlights. Unfortunately the seals for the headlight are not very good as it is just a rubber fitting and cause humidity to build inside my headlights. As of this week my driver side turn signal started hyper flashing. I pulled out the light to check it and found it corroded and rusted. I carefully cleaned and reconnected the headlight to find the white light no longer is glowing on the drivers side but the orange works fine when turning with no hyper flash. They look cool but arnt the best fitment for my car as they allow moisture to get into the headlight assembly.

These lights are great so far! 07 Xterra install. Super bright! Actually brighter than my upgraded headlights,so now I'm looking to upgrade those again. I read a number of reviews of these prior to purchasing them stating that they did NOT burn white unless you had your headlights on. For a Nissan Xterra anyway, this is not the case. They DO burn white with headlights on or off and switch to amber only when you signal. As advertised. I cannot speak for their longevity yet since I only have about a week in with them so far. I will update later to address that. About a twenty minute install. Easy plug and play. I did wrap the connection to the wiring harness itself with some tape because it looks a little exposed. A rubber boot to slide down over the connection would be an excellent upgrade for these lights if anyone from the company happens to be reading this. Especially so for a vehicle taken off-road and more apt to collect dust,dirt and moisture. I've also installed the same setup for the brake and turnsignals in the rear with the same satisfying results. Also from Syneticusa. I have about a months worth of use out of them so far and they've performed flawlessly.
