SYLVANIA 3157 ZEVO LED Red Bulb, Stop & Tail Light, 2 Bulbs

This problem with most aftermarket LED replacement bulbs is that their various designs do not emit light as efficiently as the old incandescent bulbs do. Despite what manufacturers will tell you, they are a poor mismatch with the various internal projection geometries of any given vehicle taillight. For bright light to emit efficiently, the reflector or Fresnel lens type taillights of any given vehicle have an important relationship with the bulb and must focus properly. An incandescent lamp emits light in all directions from the central filament point of the lamp. The aftermarket LED products typically emit light mostly from the broader sides of the barrel of the lamp assembly. Therein lies the issue. The LED light source cannot focus properly towards the other elements of the taillight assembly and out the rear of the vehicle. Having seen the poor visibility results of improper LED bulb choices on other's cars, I looked for a few hours to find a lamp that would work properly with my Chevrolet Tahoe tailights (internal rear reflector surrounding the bulb socket). Enter the SYLVANIA - 3157 ZEVO LED Red Bulb. Like an incandescent, it emits light from two super bright LED elements at a central focus point and towards the rear reflector surrounding the lamp socket (a common arrangement in many vehicles). Light is efficiently and brightly emitted out the lens (much brighter than the incandescent). It works perfectly on this type of taillight. Now the caveat. This particular lamp may NOT work well with the integrated fluted Fresnel lens elements on other cover assemblies. It's LEDs focus light only around and towards its socket base. However, IF there is a reflective surface there, than this lamp should work projecting the light onward through the Fresnel lens. Getting the right lamp that works well with your taillight assembly an important visibility and safety factor too.

I put these bulbs in my Nissan frontier two days ago and they are great! In tail light mode they are brighter than stock bulbs but not too bright. When you hit the brake pedal, I was really impressed! I was on a 2 lane road at night without any traffic behind me so I was tapping the brakes to see how they worked. The reflective traffic signs meant for traffic going the opposite way I was going would light up incredibly. When I got to my driveway I sat there and tapped the brakes a few times. These bulbs really lit up my street and the neighbors house across the road. I went to LED bulbs for the energy efficiency and longer life cycle than standard bulbs. I’ve been using Sylvania headlights for years and have been very pleased with them as well. I’m sure I will be very happy with these and I’m sure you will be too!! Heavy duty heat sink looks very durable. These should last a long time!

Blinking Speed was “hyper flashing” until I disabled ‘bulb out warning’ in a tool known as ForScan for my Taurus (google it). The value for the money is excellent because they are bright, use less power, and activate faster. The lights are also used for my brake lights and work perfectly. Fit and installation was perfect! A simple drop in replacement for my use. I highly recommend these to anybody who knows they will work. Simply activating faster than a normal bulb is a safety issue and can prevent an accident. If you are unable to disable your “bulb out warning” or have hyper flash issues you may need the Sylvania resistor. Else look for a CANBUS safe LED.

I bought these to replace the cheap super bright red LED brake lights I had been using in my 2005 Toyota Camry Solara. The factory tail light lenses have faded so much from the sun that the red has turned more pink over the years. That’s why I wanted red LED bulbs in the first place, and while I was replacing them I figured I might as well get something bright. The cheap LEDs I had before were extremely bright, but they only lasted about 6 months. Over two years I went through a total of 8 bulbs, so I was pretty much done with constantly replacing them. This time I decided to spend the extra money on a name brand and went with Sylvania. Under $25 for two bulbs isn’t too bad if these actually last for years. Time will tell. These use the standard 3157 base just like the original incandescent bulbs, so they went right into the factory sockets. The actual bulb is about the same size as the glass incandescent bulb, so if the original bulb fits in your housing, these should have plenty of room as well. The light output is very even and the red color is excellent. They are probably only around 10 to 20% brighter than the original bulbs, so don’t expect the huge increase in brightness you get from some of the cheaper LEDs. Personally, I’m completely fine with that. At this point I’d gladly give up some brightness for reliability. The red color looks especially good through my faded pink tail light lenses. The light is also distributed evenly instead of having really bright spots. Another nice thing is that these aren’t polarized like some older LED bulbs, so you don’t have to worry about which direction you install them. They work either way in the socket. The bulbs have a substantial metal heat sink, with two LEDs on each bulb. Hopefully that extra heat management will help them hold up much better than the cheap bulbs I was using before. One thing about my picture is that it doesn’t really show the bulb accurately. The camera automatically adjusts for the brightness, which makes the color and light distribution look different than they do in person. The Sylvania has a very clean red color in person and doesn’t look orange like it does in the picture. So far I’m very happy with the fit, color, appearance, and overall quality. The only question I can’t answer yet is longevity. After going through 8 cheap bulbs in two years, I’m hoping these live up to the Sylvania name. If they last several years, I’ll consider them well worth the extra money.

Bought them for my truck, upgraded from the halogens, super bright, only complaint is the turn signals tick really fast inside the cab

These are very very bright! The instant on and of at full brightness is much better than the slow glow from standard incandescent bulbs. I like that the bulbs actually glow red because it makes the brake lights have a nice deep red glow instead of a washed out look from the incandescent glowing white/yellow. Had them in for about a week now, no issues. But time will tell if they last long. I do expect them to last long since they are LED and I’ve always used the Sylvania brand for all my lights. I did not use these for turn signals so I can’t comment if it would work good with cars that have brake lights that also function as turn signals. Had them installed in a 1999 Pontiac Grand am, 2000 Toyota Camry, and 2001 Nissan Quest. All of them worked perfectly, fills the whole housing with light and all the running lights and brake functions work normal. When locking and unlocking the cars, the brakes still blink like normal.

SYLVANIA - 3157 ZEVO LED Red Bulb: This bulb is lower wattage (1.5/0.4W) than the white version (1.7/0.7W) 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 RED LEDs so most of the light passes through the red plastic lens that normal/OEM cars use for break/stop/running. I tried the white ZEVO LED bulb version behind the same lens and IT IS DIMMER even though it is higher 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. 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 ceter 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. 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.

I purchased these bulbs to replace the brake lights in my 2012 Tundra. Every other LED light I have used to replace an incandescent has been brighter and more noticeable than the bulb it replaced. The brightness when braking seems pretty similar, maybe a touch dimmer. The running light is dimmer and the angle of visibility is much narrower. It seems to be adequate, but only adequate. I was hoping for a little better and even went with a name brand because good brake lights are very important. I wouldn't buy them again, but they do work as advertised.

Easy to install. LED is very bright. Would recommend this product.

I ordered these for the tail and brake lights on my 1997 GmC yukon GT. The bulbs are definitely brighter and a deeper red than the clear halogen bulbs they are replacing. They do however cause hyper flashing of the turn signals. Just order the tomall 4 pin EP29 led flasher unit when you order the bulbs and the hyperflashing shouldnt be a problem. The flasher unit is located under the dash next to your e brake. If you have trouble finding it, just activate your turn signal and listen for the tick tick tick, then touch the flasher unit.. you will feel it working. Remove the old unit and plug in the new led unit. Done! Its that easy.

Product works great. Very bright.

Good
