1157 Led Brake Light Bulb, 12V-24V 1157 7528 2357 2057 BAY15D LED Replacement Light Bulb for Brake Tail Running Parking Backup Light for Car RV Trailer Boat, 54SMD White light, 2PCS

Way brighter then the stock bulb that was in the back of my 03 vulcan classic feel much safer now that pepole can actually see the back of my bike when its dark

Very bright from a distance. Now to make it flash to get distracted drivers to pay attention behind me.

It’s been two years since I installed one of this in my motorcycle’s brake light. No flickering. Easy to install, make sure you get the right one for your specific socket.

These were purchased for a 2016 Hyundai Sonata, which uses 2357 bulbs for brake lights/turn signals on the rear. On the Sonata the 2357 incandescent bulbs seem to burn out pretty quickly, like once a year. So I decided to switch to LEDs and hopefully never replace them again. For the unfamiliar, 1157 and 2357 are the same physical size bulb, with the same pins. So they are somewhat interchangeable. However, as I have found out, the 2357 has a brighter 2nd filament than the 1157 - that is the main difference. This means that with the OEM 2357 in the Sonata, the brake lights are MUCH brighter compared to the marker lights. So when you hit the brakes the brake lights are much brighter than they were (as marker lights) before you hit the brake pedal. The 1157 bulb is a similar 2-filament bulb, and is used in just about every older American car, but the 2nd bright filament is not as bright as the 2357. When I swapped for these LED bulbs, they fit perfectly. They seem to work fine. However, they are clearly an 1157, and not a 2357, even though they are compatible. And since the "dim" on the LEDs is a bit brighter than the old incandescent bulbs, and the bright is only "1157" bright, there is not a very noticeable difference when you are driving at night and hit the brakes. Yes the brake light gets brighter, but only by like 30%, compared to the MUCH brighter (like 100%) it used to get with the incandescent bulbs. These work. They look good. They should last forever. They are very reasonably priced. However be aware that they are just an 1157, and will not exactly match what your old 2357 bulb bright filament looked like. There will be less difference between "dim" and "bright". Dinging one star for that, as it was not explained. Also - to note, I have not found a single 2357 LED that is actually spec for the true 2357 spec. Possibly no one makes an exact LED replacement. So pretty much you are limited to the various "compatible" 1157 LED bulbs. I would buy them again, and in fact might replace the rest of the bulbs with this brand.

I used the light bulbs in my rv. They have just the right brightness. Perfect.
