1157 Car LED Bulbs, 4PCS Super Bright LED Backup Reverse Lights, 12V Brake Stop Signal Light Lamp Bulb LED Tail Brake Signal Rear Lamp, Car Replacement for Trucks Motorcycles

The media could not be loaded.  They will either strobe or progress the LEDs, it is not what I thought I was buying. It is NOT a constant source of light, maybe useful on a some other situations, I would not use on a car or RV.

However, the packaging leaves much to be desired. Usually when I get these kinds of kits they come in a box and anti static bags for protection in transit. This pretty much just came in a little baggy and was loose in a standard shipping bag.While they work and everything else checks out, it's a little bit of a quality concern. Mostly these will be backups for my main set so as long as they work, it's fine in the end. Switching to LEDs has saved a bit of gas on my cars. Definitely worth it if you are looking to increase your mpg on your car.

These were just what I needed to replace two lights that had gone out in my Colorado truck. They were pretty easy to replace, but I really do like the brightness of these LED lights. They are much brighter than my old ones. For the price you won’t beat the quality and quantity.

Necesitaba luz constante para marcha en revesa, en la descripción del producto nuca dice que la luz es estroboscópica.

Bought the red ones to replace the 1157 bulbs in my tail lights - 2 filament bulb for lights on and braking.What I failed to notice was the last part of the description that says, "flicker modes". These lamps flash instead of maintain a solid light. This would be fine if it was only when the brake lights are supposed to illuminate, but the flash happens with only lights on too.The other negative to report, is that having the lights on OR depressing the brake pedal will illuminate these LEDs identically, that is no difference in brightness between the two. This carries over to when the brakes are applied as the lights ARE ON as well - there's NO INCREASE in brightness to warn others that you're braking!There is two contacts on the bottom of each bulb, and the twist pins are offset from each other - just like a real 1157 dual filament bulb. But no difference is seen when applying brakes with the lights switched on at the same time. This could cause an accident!I do know for sure that 1157, dual contact, LED bulbs can function like the incandescent bulbs, because I have older ones already in there that function properly. I'm not clear what you could actually use these for...It's a thumbs down from me. Since one star is the lowest score, then that IS the same as giving 0 stars!

The lights stands out in terms of polarity, being they are red. Over all a easy installation. The performance, was as expected. The brightness of the red illumination dims the visibility in my opinion unless you have clear fixture.

Super bright blue light but they only worked as a strobe. Not what I was expecting or what the description said.

I used these on my camper trailer to give the brake lights a little more visibility.
