SYLVANIA - 3157 ZEVO LED Red Bulb - Bright LED Bulb, Ideal for Stop and Tail Lights (Contains 2 Bulbs)

I didn’t do a side by side, but I’d say they’re on par or maybe slightly brighter than the incandescent they replaced. If you’re looking to go LED don’t make the mistake I did, go straight for the zevo line. I originally bought a sylvania bulb, they were round. They were ok. Decided to try the zevo and ordered one as a test, woah. Night and day difference. Much better designed for a reflector housing. They really fill in the whole housing unlike the old round bulb that just kinda made some light. Mind you the round bulb had 6 sets of 3 LED chips! Ordered a second set for the front. Was a little skeptical being these are a single LED chip each side but they have a nice beefy metal heat sink. So long they stay cool they should last no problem. To review the 1157 red bulbs, also very good bulbs. Same setup as the 1156 amber but in red and will do stop/tail. I originally bought Phillips ultinon and boy was I disappointed. They did ok but were noticeably dimmer, especially pronounced side by side to the incandescent they were replacing. Do not bother trying other brands, until they get on the level of the Zevo line by sylvania, spend the money and get the Zevo. I’ve heard the non Zevo of the same style by sylvania are essentially the same however they don’t use a metal heat sink. LED bulbs can run hot and when they do they will not last. These are nice and bright even in direct sunlight. I should have spent the money the first time, instead I spent more than double in the end buying another bulb first.

Great lights!

Compre estos LED como reemplazo para mis luces de posición/direccionales frontales; Los LED son buenos, las luces de posición no brillan mucho pero en condiciones de poca luz si se ven (Obvio porque no son luces de conducción diurna), las direccionales brillan mucho más y a plena luz de día son bastante visibles. En general son unas excelentes luces. Como detalle es que tuve que reemplazar el relevador original de las direccionales por un relé electrónico (Novita EP34) para poder eliminar el hiperflasheo con las direccionales.

These LED's are very bright. I use them on the front turn/parking lights on my 2005 Acura TL. The deep orange lens in the front turn bright yellow when these bubs are activated. Please look at the pictures. They are even brighter when the turn signals are flashing. The description on Amazon has a display showing which LED, amber or white, you should use with which lens color on the car. I tried the Amber LED with my Amber lens and the brightness was very poor...worse than the incandescent. I then bought this white LED and you can see from the pictures and the video, it's very bright. Always been happy with the reliability of Sylvania.

These bulbs are not round as indicated in the pictures. They are the flat design which, in my case did not work for my application. I got a refund however returning shipping was almost as much as the bulbs....FYI...bad seller for not having correct picture indicating product! This picture below is what you get.
