SYLVANIA3157 ZEVO LED White Bulb - Bright LED Bulb, Ideal for Daytime Running Lights (DRL) and Back-Up/Reverse Lights (Contains 2 Bulbs)

SYLVANIA - 3157 ZEVO LED White Bulb: This bulb is higher wattage (1.7/0.7W) than the red version (1.5/0.4W) on both segments (high and low power 3157 'filaments'/LEDs). If used as a single filament 3156 bulb you get the bright filament/LED, the low wattage 'filament' is unused. LED facts: This one uses White LEDs so most of the light is absorbed by the red plastic lens that normal/OEM cars use for break/stop/running. I tried the red ZEVO LED bulb version behind the same lens and IT IS BRIGHTER than the white even though it is lower wattage. THIS IS CORRECT. The white LEDs emit a low percentage of light in the red spectrum so most of the white LED light is absorbed which makes for a dimmer light after passing through a red lens. Most of the red LEDs light (high percentage) passes through a red lens. The white one is good for the backup light only and also, perhaps, a amber lens. An issue, there are two sides to this LED and a large center heatsink. This makes for a no-light center spot. Since the light is so bright this is a minor issue (for me). Regular bulbs have a center bright/hot spot so this LED design is the opposite. Also, since the LED is two sided they will emit most light either up/down or left/right. In my 1997-2000 Caravan design tail lights I get both up/down and left/right. This is not a big issue since the lenses are a good design and the light both bounces around well and is captured by the Fresnel lens facets and reemitted in a good pattern. Matter of fact the lenses emit is a nice full bright glow instead of having the usual hot spot in the center. Different but nice. [from my red ZEVO review, use the red one behind your red lenses] Remember, if used for the turn signal light you'll have the usual fast blink issue. You'll have to install a 6/4/3 ohm resistor to stop the fast blink.

Fit and worked perfectly. These lights light up really well on the road. I am sure they will last for a while.

ZEVO 3157 works well for DRL application in 2011 Chevrolet Avalanche. These vehicles, in addition to other GM trucks, are constantly burning out DRL bulbs. I don't know why GM used a dual filament bulb for this application, since only 1 filament is used. Probably just to save a couple pennies. Maybe these will last longer.The color is bright white LED for great visibility. Much more noticeable than the standard 3157 bulbs. The color temperature is intense but they seem to have less light output (less lumens) than a standard filament bulb. Perfect for DRL but maybe not good for lamps that are used for illumination, such as back up lights.

These bulbs would not fit in my housings, 21 F150, without removing the fins/protrusions on each side of these bulbs. Look at the photos and you’ll clearly see them. My stock bulbs do not have them on any of the rear bulbs. I had to use a utility knife to remove them and then they fit. I strongly recommend pulling a stock bulb to see if yours have these fins or are smooth down each side as mine were. If your bulbs don’t have these fins then you’ll know it’s either cut them away or return them. Just a heads up so you know…good luck

Used to replace backup lights in an 1999 GMC truck. Excellent upgrade. The backup lights now double as rear "running lights". Much-Much easier to see during the day than the old incandescent bulbs.Looking forward to seeing how long these last, but aluminum housing design sure looks far more durable than many of the other LED bulbs I've been using.

Luz brillante y de fácil instalación

I bought a set of these 3157's for my 2020 S550+ model Mustang's reverse/back-up light to replace the incandescent bulb (only needed one fir the Mustang). It worked plug and play right away, no issues. I didn't test their claim that it worked regardless of polarity simply because I forgot. I saw that it worked first time, and just let it be. It is brighter, amd throws no codes or flickering. As far as value for the money, I would have to guage that against it's longevity, so I cannot fairly evaluate that... just installed yesterday. Of note, I bought these after trying a bulb from Diode Dynamics which claimed to be plug and play for my car.... that one did NOT work, so I got these. I will also be installing these 3157s into my 2019 Ram Cargo lights and the High Mount third Brake Light over the bed. I haven't installed those yet, but after the Mustang's success, I have no doubts.

As others have said, these are not very bright. They are going back...

Installed in a 2016 f150. Not close to as bright as the halogen which seems a bit silly for Sylvania. Hyper flashing in both turn signals can be fixed with a resistor but why is that even an issue these days. Sylvania should have made them to be a bit higher wattage or just go buy regular ones for 10 bucks. The lights when locked into their socket also have to sit at an angle to fit back into place so not locked into place fully sealing the gasket. If you’re going to go LED , you may as well get the full tail lights. This may not be the same issue for other vehicles. Just the 2016 f150. Bought them , tossed them.

Not powerful at all
