I will try to keep it quick and to the point.The Good: Fit right into the socket no problems. Looks just like the picture and lights fairly bright. There is a slight noticeable difference in brightness from factory to these. A little brighter. Good application as long as you are not replacing a dual filament bulb that requires repeated flashing - i.e. turn signal. Brake and hazard lighting works. Ordering, processing and shipping was acceptable.The Bad: I bought these to replace the rear dual filament incandescent bulbs that serve as my brake, turn signal and night time driving lights. Lights work flawlessly until you use them as turn signals and then they hyper flash. (Hyper flash meaning flash about 2-3 times faster than a normal turn signal flashes). I just don't think the technology is there yet so I don't fault the bulb. I also tried another bulb that had load resistors built in and they did not perform any better.P.S. Something I did learn if you are going to replace your OEM incandescent brake, turn signal, etc with LED, order a bulb that actually illuminates the same color as the lens. So a brake light - order a LED that illuminates red without the lens. WHY? More light passes through. I tried this on the recommendation of the manufacturer I purchased the second set of load resisted lights on and while I was skeptical, I wanted LED replacements. Indeed he was correct. There is a noticeable difference between the LEDS for this review (white light) and the 2nd set I ordered from another manufacturer (emits red light). In the end I had to return those as well for the same reasons but thoughts I'd share.

They will not work in any situation which uses a dual-filament bulb such parking-light / brake light combo, or turn signal and parking light. I installed in my parking light socket which is a single-filament that is always lit when headlights are on. They are nobrighter than the bulb they replaced.I don'tknow about longevity, so hopefully they at least last longer. The contacts which go into the socket are very flimsy and easily bent. Removing the bulbis guaranteed to bend the contacts. The Sylvania bulb anchors the contacts so you can pull them in and out. These are attached only at 1 end. I had to straighten all of them as I put them into different positions.

Not as bright as I hoped but they do work ok...just a little bit brighter than a reg/normal bulb...good thing they were low cost

highly recommend these bulbs put them in the reverse of my truckand look coolI recommend , surely not waste your money

No good

good price
